A library inside a cafe in Chiang Mai, Thailand.

3 trips instead of 12, but I would not change a thing about that.

Here we go again. This time only with a 2 month delay, so definitely improvement. 2025 has been for me a great year, even with a small setback that felt like a huge one at a time. Looking back, I am very grateful about everything that happened last year. It challenged me. It made me ask more questions. It made me know more about what's actually important to me. And it rewarded me far more than I ever hoped for.

First and most important: I'm getting married to the love of my life and my best friend! 3/10/2026 save the date! I cannot describe in words what this means to me as I look forward into the future. Feeling lucky is a big understatement.

I am also moving to a new place, which should be done in 2026, and I look forward to having more space for us and for our hobbies, as well as more light for my plants!

Overall, I ticked a lot of goals when it comes to my role as a Software Engineer. I worked on my hobbies, my routine and, of course, my trips!

Goals for 2025​

In my 2024 year in review, I again set goals for myself. Let me review them, in order.

• Get promoted at work.

So happy to have achieved this. Even if it did not involve a title change, it gave me the confidence that I was relevant in my work, I improved Teams and learned to own features and outcomes.

• 1 course from Frontend Masters done.

Done! Angular fundamentals was indeed helpful, even though the course did not cover the latest way to use Angular, via signals. But still, it allowed me to understand some things that were completely alien at the time.

• Refactor Downshift to Typescript and release useTagList.

Almost done. Releasing useTagGroup at the beginning of 2026 and, as part of the work, commenced the migration to Typescript. Cool stuff!

• Read 6 books at the very least.

Here it's not so good, I really need to get my reading velocity back up.

• Go to Thailand.

And what a trip that was ... 25 days of pure sunshine, fantastic beaches, spectacular islands that were part of the Avatar landscape, and more coconuts that I could count.

• Travel at least 6 times.

Only 3 times, but the length of each trip was significantly larger than in any previous years.

• Keep doing sports at least 4 times per week.

Yes! And some cardio in between. Installed Freeletics and their routines fill the gaps where my previous training schedule completely missed. I dread Bulgarian splits, damn.

• Start waking up at 6 AM again.

Work in progress. Managed about 6:30 AM and I think, for now, it's fine.

• Start running again, at least once a week.

If it's not running, it's gym cardio. Still not consistent, but it's better than before.

• Decrease my phone screen time to 1 hour and 45 minutes per day.

This is so hard ... now I also get shown the Freeletics usage. But overall it's still around 2 hours and 30 minutes. I need to pursue this goal harder.

Overall I believe it's quite good, honestly.

Coding Stuff​

So, got promoted to 64 at Microsoft, which involves being a seasoned Senior Engineer. I delivered very high profile initiatives for Microsoft Teams and improved the fundamentals of the app, improved transparency and helped with the hiring effort.

In spite of this success, I decided to try something new, and I joined UIPath in September. Even though the goal sounded like something that will help me grow further, it turned out to be mistake. The work environment was not something I could thrive, and it was obvious from my first weeks that I will not succeed there. Luckily, my friend working at MUI reached out in the meantime and convinced me to apply for the MaterialUI library maintainer role, just in case things might not work out with the current role. It was divine intervention, and it saved me from piling more frustration than I already did.

This role allows me to focus on the same kind of work that I'm doing at Downshift, but with a way broader scope. Speaking about Downshift, I doubled down my effort in order to improve both the library offering (useTagGroup) and also the fundamentals. By working on these great libraries, and potentially others such BaseUI and MUI-X, I look forward to improving myself and the products, and come up with subjects that are worth presenting at tech conferences, which is something that really excites me.

Hobbies​

I stopped taking salsa classes with a heavy heart, but with at least 4 days per week in the gym, it's really hard to just stay at home and appreciate some time not doing much, or just cooking something and hanging out. I just had to do it, and I'm not sure if I will resume going again, even though I miss it very much.

Another hobby that suffered is hiking, but I plan to pick this up back in 2026. It always helped me, both physically and mentally, and I see no reason why not doing it more again. When it comes to nature, I confess that many of my plants decided to die, after they were barely surviving with not much sun exposure. Nothing I could do about it, yet.

I did not read that much last year, so the list is quite tiny:

1. Lost Illusions, Balzac. Always liked his literary style, and one of his favorite subjects: the coming up of a character that, due to their superficiality and lack of spine, ended up in a tragic downfall.
2. The Beautiful and Damned, F Scott Fitzgerald. Great book, but, again, like the first one, a very sad story.
3. The Bhagavad Gita. Interesting poem, meant to explore the feelings before making tough, but necessary choices.

Travelling​

This year, there were far fewer trips, but they were longer.

• Milano, Lago Maggiore and Cinque Terre. The Easter trip was great in spite of the weather not being the best. It did not allow us to fully explore Maggiore by bike, and when we went to Cinque Terre, it rained all day.
• Zakynthos and Bari. The Greco-Italian trip was a perfect combination between beach holiday and a city break. It involved a great cruise around the Zakynthos Island, the perfect Italian cuisine of Bari and a series of road trips to Matera and Monopoli.
• Thailand, Singapore and Kuala Lumpur. That trip that was absolutely perfect. A trip of 25 days of exploring in Southeast Asia, that took us from the temples and skyscrapers of Bangkok, to the elephant parks and nature of Chiang Mai, to the pristine beaches and incredible island landscapes of Krabi and Phuket, to finally to the city of the future, Singapore and, at the end, to the very modern city of Kuala Lumpur, which also has food to die for.

I can't wait to write about each and every trip, since they were absolutely stunning. 3 trips instead of 12, but I would not change a thing about that.

Wrapping up & Goals for 2026​

2025 for me was a great year. I achieved a lot, and received more than that in return. I am grateful for it in every single way. It's hard to top it, but I will do my best in 2026. I'm writing this on board of my flight to Geneva, my second to last stop for the MaterialUI team event in Flaine, one of France's most beautiful ski resorts. I'm happy with how everything turns up, and that only motivates me further to achieve more in 2026. If I could think of a list of goals:

• 2 courses on Frontend Masters, one to improve my fundamentals and one to learn something new.
• Improve MaterialUI suite of libraries and be recognized for my contributions.
• Remove Downshift's useMultipleSelection hook.
• Refactor all Downshift hooks to use Typescript.
• Improve the library's perf and quantify it.
• Write 2 blog posts about tech and what I've learned.
• Create a presentation and submit it to a conference to be accepted.
• Decrease my mobile screen time to 2 hours.
• Read 6 books.
• Get in better shape, target is around 78kg.
• Hike 6 times.
• Go to a concert.
• Snowboard 3 times.

I have set quite a few goals for 2026, as I feel that I want to use the momentum I have in order to improve the discipline that was partially lost along the way. I believe 2026 is going to be a great year, I look forward to fulfilling my plans and, most importantly, spend more time with the people I care about the most.

Teatro Massimo in Palermo.

If you are keeping a strict diet, avoid this place like the plague.

Sicily deserved a part 2 after the Catania trip, and Palermo was the natural next stop. It's also conveniently situated near the beach, as well as the nearby town of Cefalu, which was also on the trip list. We were so ready for a few days of Dolce Vita, andare in spiaggia, mangiare i cannoli and enjoying some ancient history combined with great scenery.

Palermo Food​

Not going to sugar-coat it: Sicily is the perfect place to fall in love with life. Palermo is simply pure romance, and has so much to offer. We were lucky to have booked an airbnb right next to the Vila Maqueda, the place to be. Every restaurant and eating place was at most 5 minutes away, and, as you probably imagine, we took advantage. If you are keeping a strict diet, avoid this place like the plague. Otherwise, well, brace yourselves. We did not eat cannoli that much until we got to Sicily, purely because there was nothing special about them in any other place. Here though, totally different story, as they were just so good, the cream was perfectly textured, the flavour just right, and the crunch exactly like in the commercials. Cannoli&Co for reference, you're welcome.

Also here we discovered something else that we did not eat before just because when we tried they were meh. Star number two: arancini. Balls of fried rice with mozzarella and proscitto? Yes, please, keep them coming. Other culinary stars were here as well, here in Hollyfood:

• gelato that is always welcome in any moment of the day.
• pizza that's handmade.
• aperol spritz to keep the vacation mood going.

These are always the super stars of Italy and Palermo did not come short in delivering them. Oh, to make sure I won't forget. There's another Sicilian star here, something I did not have before, and which proved to be worthy of admiration: the Sicilian gelato brioche. A. Ma. Zing.

I'll stop. I'm hungry.

Palermo Sights​

So, the action is mostly around the Via Maqueda. We mostly covered it from the Mariano Stabile intersection all to the way down to the University. It's the place where we got most of the food I've mentioned above. It's a mix of touristic hot spot and a locals get toghether place, especially during the evening, around the Fontana Pretoria, and for good reason. The place and its surroundings offer a great show of architecture, starting with the fountain itself, nicknamed the "Fountain of Shame" due to its nude statues.

Quattro Canti - Piazza Villena	Inside the Teatro Massimo

The Quattro Canti are also gorgeous, displaying the Baroque style very well. Baroque can also be found on the nearby Chiesa e Monastero di Santa Caterina d'Alessandria, where it's combined with elements from both the Gothic and Renaissance architecture styles. Finally, Church of Saint Mary 'dell'Ammiraglio' is also close to this beautiful cultural ensemnble. It's older than the others, built in the 12th century, but equally beautiful and worth a visit. Usually, when visiting Italy, churches are worth a visit, given all the effort that has been put into building and maintaining them. From my experience, Rome has the best, but the ones in Palermo are also truly special.

What we also liked was the inside of Teatro Massimo, where we enjoyed a guided tour of the place. It's where the Godfather III opera scene was shot, so we could not miss it. I'm making it a personal objective to return to Palermo and enjoy a performance there. Adding it to my list, along Teatro alla Scala in Milano.

In our city walks we also went by the Palermo Cathedral, Villa Bonanno and Palazzo dei Normanni, when we decided to leave the Maqueda and take a right on the Vittorio Emanuele. On our way back we took a slightly different route and briefly went in the Chiesa del Gesù di Casa Professa. By going off the beaten track, and on the more back streets of Palermo, we did feel the Sicilian vibe a bit better, and it reminded me of those places in Catania and some parts of Naples. The buildings are not very well maintained, and I would probably avoid those kinds of places during the night. Towards the evening, we withdrew to the "safe space" of the main street. I'm probably overreacting, as the streets were actually not that far off the city center.

Another trip we did was to the Villa Giulia park, where apparently we stumbled upon some photo shoots of very young people dressed formally. Apart from that it was a beautiful stroll along the alleys with palm trees and flowers. Palermo is a beautiful place to enjoy life and relax, where the only stressful thought is how much you eat.

Cefalu and Mondello​

Road trip part! Since we were going to be in Palermo for quite a few days, we decided to try some nearby sights. First on the list, the town of Cefalu. It's the King's Landing kind of place, with narrow streets and packed houses, all on the shore. It has a couple of landmarks as well, like the Duomo di Cefalù, a Norman cathedral built in the 12th century, back when Sicility was ruled by Normans after being liberated from the Arabs. Towering Cefalu is Ruderi del Castello di Cefalù, the ruins of a castle alsop built by the Normans to defend the place. Conveniently situated on top of a rocky hill, we managed to climb on top, with quite some difficulty I might add (I was wearing jeans), but we eventually made it to the top and enjoyed breathtaking visuals over Cefalu and the surrounding area. Porta Pescara was also a great view, as well as the Bastione di Capo Marchiafava and the nearby beach.

Cefalu View	Palermo Cathedral

As for Mondello, it was our option of spending a day on the beach, and it's a very short ride from Palermo. The town is very cute, and it's famous for it's fine sand beach, which we enjoyed very much. However, apart from the beach, we did not find much else to do there, as the food and drink offerings are quite poor, really. Next to the beach, the area is filled with pretty houses, and it gave a relaxing place kind of vibe, where you just go and chill for a few days.

Wrapping up​

Given it was my second time in Sicily, I must say I enjoyed it more than the first, and I would still considering coming back (now that I've watched White Lotus). There's also Mount Etna to see, as well as Syracuse, Corleone maybe? Oh, and definitely the Teatro Massimo show. Definitely there are enough reasons to go back there, on top of the cannoli, obviously.

View over Lago di Garda from Riva.

(...) it's the place I will remember for the rest of my life.

I've been meaning to write a yearly review, and I aim to stick to the plan. It's already June 2025 and 2024 came to a close quite a while ago. What can I say? I've been a bit busy, and maybe a bit uninspired. However, 2025 has been for me one of the best years in my life, and I've wanted to share a bit about it. There were some good parts, some not so good, and some that were actually amazing. I've met the love of my life, and for the first time ever, things have beginning to feel as they should have. I feel I'm in the right place and I'm excited for whatever comes next. I'm happy.

Goals for 2024​

In my 2023 year in review, I also set some goals for myself, and there were some successes.

Let's see.

• Finish the A11y course and do 2 more courses on Frontend Masters. Same as last year, but I'll actually do it.

  Did it, it's done. It was a good course, but not as useful as others to be honest. I would recommend it for accessibility beginners, not so much for experienced.

• Read at least 10 books. Again, same as last year.

  Fell short, unfortunately. How short? Keep on reading.

• Go on a trip to Asia. Anything really, Japan, China, Thailand. All three. I don't care, but I want to go there.

  Nope. But I feel 2025 has something in the works.

• Bump Downshift to v9. We do have in plan some API changes, apart from the fixes we want to implement.

  Yep, we're at v9, and we improved the API and Typescript.

• Cook 3 new recipes.

  I didn't. But I "helped".

• Hike at least 6 times. Once every couple of months. Should not be too difficult.

  Exceeded it, by one, and most of the trails were in Tenerife!

• Make a big move. It has been quite some time since I did not do anything radical, ever since I came back from Prague in 2020. I feel that it's time I changed something dramatically about myself.

  Unfortunately nothing to share here.

• Start doing yoga.

  I'm still struggling to do things at home, whether it's yoga, reading, dancing.

It's a mix of things, no doubt. I believe my morning routine suffered a bit, and, as a consequence so did some of my goals.

Coding Stuff​

I became more confident in my role as a Senior Engineer in Microsoft, and led a few critical initiatives, which are now in production by the way. It feels great to see your work used and useful, and I would like this to continue in the future. I am lucky to be able to choose what I would like to work on, and even though these are becoming quite uncertain times for software engineers, I'm confident that my dedication to deliver a great experience for users, build things the right way and learn continously will help me be successful in the future as well.

My Downshift continued, and now I plan to refactor it to Typescript, while also improving its API offerings. The refactor is not a trivial one, given all the generic functions we use, but it's a great challence and I enjoy working on it so far. As part of the developer experience I was able to write an article about how we inform our cosumers about calling the API correctly.

And Downshift was not my only OSS contribution. I'm happy to say I successfully pushed a change in jest-dom and also wrote an article based on this contribution.

Hobbies​

I continued taking salsa classes and feel that I improved quite a lot. I'm not going out as much as I used to, but still joined a couple of dance festivals, in Sunny Beach and Brasov. However, I miss bachata to be honest, but there is literally so much we can do. I am going to the gym 3 times per week, with an extra day which is either basketball or body bump. Working out became a priority since I fell it's becoming more difficult to stay in shape. Maybe it's because I'm not running as much as I used to, and I believe that cardio helped me significantly to lose fat and just feel better.

Land of Legends Antalya	Palermo Architecture

I'm happy that my girlfriend supports my hiking hobby directly, and we went on a few trails both in Romania and in Tenerife. When I went to Tenerife by myself I also included some trails in the itinerary, and they were so spectacular. I will always remember the Mount Guajara trail where I kind of had a heat-stroke, or the trails around Punta del Hidalgo in the Anaga natural park. It always feels great to climb stuff, it helps clear the mind and the sights are always incredible.

Books​

Same as before, 10 books at least, but this year, wow, it has been quite bad. I'm not proud of it, and 2025 feels the same unfortunately. In any case, the books I managed to read were not bad at all.

1. The Great Expectations, Charles Dickens. It was a great tale, a bildungsroman, of Pip, and how he perceived family, friends, love, and society in 19th century England. I might re-read David Copperfield after this, since I remember nothing since I've read it in childhood.
2. The Intelligent Investor, Benjamin Graham. Filled with a lot of terminology and graphics and studies, it actually proved to be quite useful to my amateur investor mindset. Or should I say passive?
3. Animal Farm, George Orwell. Probably my favorite out of the whole list, it opens up a lot of doors of thinking about politics, work and the world in general.
4. The Da Vinci Code, Dan Brown. I had little expectations from it, given that I'm not really a fan of the genre, but it impressed me by the pace of the story, as well as the plot itself. Really good!
5. The Grapes of Wrath, John Steinbeck. A story about a family that confronts the devastating effects of the Great Depression over the Mid West. It was really hard for me to keep up with their story filled with unfortunate events, but I was impressed by their willingness to keep on going in their search of a better life.

That's it, that's the list. I need to do better next year, damn.

Travelling​

I thought 2023 was crazy. 2024 was incredible. Take a deep breath, here they are:

• Madrid, January. A great start. A great city, simply beautiful, everything about it was great. I fell in love with it, would definitely return for a Real match.
• Athens, February. A great continuation. A trip about coffee, food, long walks, and the Greek architecture.
• Bellagio, March. Biking around Lake Como is always a good idea!
• Tenerife, April. This is paradise. So much to see, so much to do, 2 weeks is simply just not enough. It needs at least one more trip. Oh wait ...
• Palermo, May. It was a great follow up to the Catania trip, and it's the place I will remember for the rest of my life. Will come back for an opera show.
• Prague, June. Working trip, but always great to be back over there.
• Lago di Garda, July. Biking around the Garda lake is always a good idea. It was refreshing to see the lake again, this time on 2 wheels, after a previous cruise we did a few years ago (also a biking trip). Definitely a place to visit again and again.
• Vienna, August. Despite the hot temperatures, the city is a gem, and we enjoyed both the Schonbrunn and mami im vierten brun place.
• Stockholm, September. Interesting city, a great follow up to Oslo from the year before. The cruise around the city canals was really cool, and the pizza was not bad either.
• Antalya, September. Shifting gears, enjoying the beach vibes one last time for 2024. Or not. Anyway, it's great to grab a pumpkin cream cold brew and then go to the beach bar. Antalya probably impressed me the most, apart from Tenerife. Definitely a place I will return soon, and not for the all inclusive.
• Budapest, October. It's one of the best cities to eat in, period. And the sights, wow. The Parliament, Buda Castle, Fisherman's Bastion, and of course, Gellert, the legendary place from Hitman.
• Seville-Tenerife-Valencia, December/January. Because Wizz Air direct flights are expensive. Anyway, one of the best trips in my life. So far.

12 trips in total. I will take that, thank you very much.

Us hiking in Tenerife

Goals for 2025​

Let's see.

• Get promoted at work.
• 1 course from Frontend Masters done.
• Refactor Downshift to Typescript and release useTagList.
• Read 6 books at the very least.
• Go to Thailand.
• Travel at least 6 times.
• Keep doing sports at least 4 times per week.
• Start waking up at 6 AM again.
• Start running again, at least once a week.
• Decrease my phone screen time to 1 hour and 45 minutes per day.

Until next review folks! I hope you also had an amazing 2024, and 2025 will be better!

There's also a Starbies on the promenade, perfect to sip on a Cold Brew while watching surfers just getting destroyed by the waves. Oh, bliss.

Surf's up! It was time for a much more longer trip, and the place we chose was Paradise. Tenerife does have a reputation. It's a go-to place for many Europeans, as it's not very far from home, it's warm, it's beautiful, and there's so much to do, from lying on the beach to hiking next to a volcano. Our hopes were higher than the volcano, honestly, and we were not prepared to be disappointed.

Las Americas & Los Cristianos​

We initially decided to book an airbnb in the Las Americas surfing and slow lifing part of Adeje, but unfortunately, the place turned out to be quite bad, and we moved out the next day. Not a very good start, but we eventually were over it, as we moved to a better apartment in the town next to Adeje, Los Cristianos. As a rule of thumb, make sure the accomodation has great and many reviews, otherwise there may be surprises, and, frankly, you don't want to stay in a dump while in Paradise.

Buenavista del Norte	Pine Forest on the road to Teide

Los Cristianos is a nice place to stay while in Tenerife. The weather is great, it has a few beaches, albeit quite standard city beaches. The more exotic ones are further away, we'll get to those in a minute. We found a nice Romanian owned coffee shop in town, Norio, which was great, even though there was no speciality coffee option. Too bad. However, for food options, well, oh my Lord. Just a few: Palmera for brunch, El Cine for fish and Sal Fina for Italian. What I liked a lot was the promenade along the beach, that stretches from Los Cristianos all the way to Las Americas. It's a great place to have a run during the morning, or a relaxing walk at dusk. There's also a Starbies on the promenade, perfect to sip a on Cold Brew while watching surfers just getting destroyed by the waves. Oh, bliss. Oh, probably important. Rent a car.

Now, I get it. The place is 100% for tourists, no doubt. Half of the UK was there, especially in the Las Americas part. But for good reason. When you just sit on the beach, or on the balcony, and just look into the distance at the landscape filled with picturesque mountains and cliffs, you realise that the place is really special, and you're suddenly happy you're there. I was for sure, and was terribly excited to discover some nature, which brings me to ...

Mount Guajara​

Was it a great idea to choose the Mount Guajara trail for a hiking session? Definitely. Was it so poorly planned that everything turned out to be on the edge? Also yes. At the end of the trip, I was exhausted, sunburned, out of water, the sun was setting and it became quite windy and cold. All worth it, and lessons were learned.

The Teide National Park is probably the number one spot in Tenerife, with a scenery so incredible you'd probably mistake it for Mars. It's really special. Right across the famous Teide volcano, there's another peak, not as high as the former, but definitely imposing: Mount Guajara. And, surprise, surprise, it has a hiking trail that starts from the Cañada Blanca, just off the main road. The trail itself is not easy. There's a lot of walking at the start, then the climbing begins steadily. The difficulty itself is not the climbing itself, but the steady pace you need to have in order to reach the peak in time, as well as come down the other part of the trail, that's more abrupt. It may be a better idea to do it the other way around, climb like hell and then steadily come down to the summit.

Mount Guajara Trail landscape	Teide Volcano

And there's the sun. Look, the landscape does look like you're on Mars, and there are no trees on Mars. No shade. Zero. Consequently, it would have been a great idea to pack enough sunspray, more water, and a cap. Apart from these minor inconveniences, the trail offers incredible views and it's enough challenging such that, when coming back to the car, you're filled with a refreshing sense of accomplishment and happiness. AllTrails was my hero and helped me not get lost, even though the trail itself is quite well marked physically.

And there's the main view, at the top. There are a couple of reasons to climb on top of Mount Guajara. Firstly, you can see Mount Teide very well from the top, and, well, everything else around you. It helped me trully appreciate the beauty of the Teide National Park. And secondly, Mount Guajara served as an astronomical observatory. I would assume that it's a great place to spend the evening and see the stars. All in all, even though the trail really makes you work for the views, I would say it's a must do if you're a hiking fan and plan to go to Tenerife. Just, pack accordingly, please.

Mirador Aguaide​

Chaning gears, but not the car, I chose as my next hike to be in the Anaga Natural Park, also a must see if you're spending time in Tenerife. It's on the opposite side of the island, and it takes a bit more than an hour to get there from Los Cristianos. Once I got there, the scenery changed abruptly yet again. No more Los Cristianos beach vibes, or mountain volcanoes on Mars. This time, I was deep into the Jumanji jungle, and it was just staggering! We parked the car at the Cruz del Carmen, a parking spot that served as the start of the trail, which was supposed to be a downhill hike all the way to Punta del Hidalgo. The parking place is convenient, although it lacks any security cameras, so don't forget to lock your car.

Since the trail was supposed to be quite long all the way to the end, I've decided to cut it short, at least to the Mirado Aguaide, especially because getting back was supposed to be much harder. Starting the trail, your usual vine forest trails, all dark, humid and full of mud. However, after about half an hour downhill into the forest, the trail cleared up, and the really beautiful scenery started to show itself. We were walking on the edge of the cliffs, with a deep valley to our left, and the cliffs were filled with trees, aloe vera as tall as trees and some picturesque houses scattered around. This view, combined with the gorgeous sun rays we cought, made the view so good that it was nothing short of perfection.

Cruz del Carmen Trail Landscape	Masca Landscape

We walked next to ravines, then some people's homes, then through a sheepfold, and eventually we reached the village of Chinamada. There, we took a 2 minutes break, before doing the last part of the hike, a 10 minute uphilll to the scenic spot, Mirador Aguaide, our destination. From here, we could just admire the jagged peaks of the Anaga, like a fortress against the vastness of the ocean. It was quite late and we had to get back, but the view was just intoxicating, and it made me feel so happy to be alive and be part of this beautfiul world. I'm lost for words, but really, if you're in Tenerife, I would definitely recommend going there, either from Carmen, or from Hidalgo, or just by car all the way to Chinamada, although I do believe the feeling is more potent after a few hours of breaking a sweat and enjoying the Anaga hilly landscape.

Life's a Beach​

Enough hiking (for now), let me tell you a thing or two about the beaches in Tenerife. Yes, the ones in the South are quite good to just relax, grab a coffee from Starbies, or two, go for surfing and whatnot. Los Cristianos or Duque ar really good, but it's not setting them apart in any way. Just your regular golden sand beach, close to the shopping center, a few palm trees here and there. Las Teresitas is probably more impressive, due to its size, so if you're planning to stay or take a trip to Santa Cruz, definitely check that out. I especially liked the fact that the water was quite warm, warm enough to go for a quick swim.

Bollullo Santa Ursula Trail Landscape	Benijo Black Sand Beach

On the other hand, I believe that Tenerife is actually more about natural beaches, and there are quite a few of them, especially those with black sand. Those are, indeed, quite special. We went to Bollullo, right next to Puerto de la Cruz, and it was a blast! Great scenery, perfect sand, beach bar up the coast, and a great sunset mix of colors that were perfect for taking pictures. Other great beaches we went to were Playa del Roque de las Bodegas and Playa de Benijo, but these are more up to the north, in the Anaga Park region. However, picture this. You just came back fron a hiking trip in Anaga, it's the afternoon, and you just throw your hiking shoes, crash on a beach with black sand and enjoy the calming sound of the waves.

More Trips and Hikes​

One nice hike we did was around the Plaja del Bollullo, in the Santa Ursula area, which was more like a walk overlooking the beaches. Until the walking stopped, and a full climbing session started, until we reached the Mirador a Santa Ana, with a great view over the area. Afterwards, it was time to enjoy the rest of the day on the Bollullo beach, which you probably guessed by now, it's my favorite. Another good hike we did is in Anaga, starting from Benijo and climbing to the Mirador Cabezo del Tejo. The landscape on that part of the Anaga is not as impressive as the one around Aguaide, but it was still worth to enjoy the Anaga cliffs embracing the ocean. All from an altitude of 900m.

Last hike I will mention, which is more of a walk, is on the road to the Teide national park, as you're going from the South. This area is covered with pine trees, which, again is different from other areas of the island. And this is probably the most incredible part of Tenerife. It's not a big island, but there are so many different areas in terms of vegetaion and landscape, that you can easily forget that you're on the same island. Anyway, this walk is through a pine forest, which is split into 2 by a swathe of basalt, a kind reminder that the volcano is still active.

You probably think that all I did during the trip was hiking, but that's not really the case. We also went for day trips to different areas of the island, all of which I really recommend. Some worth mentioning are:

• Mount Teide by cable cart, it's really cool to be on top of the volcano.
• Masca Village, just make sure the driver is not the emotional kind, as the road is really challenging.
• El Rayo Buenavista Del Norte, perfect for a walk close to the ocean and taking pictures with unique landscapes.
• Garachico, which has a great restaurant, Silogia.
• Puerto de la Cruz, where I was introduced to the Zaperoco.

That's a Wrap​

Tenerife is probably one of my favorite places so far, along with the Algarve in Portugal, or New York. There's so much to do, and so much to see, and the weather is almost always great. Consequently, I've went there a second time last year, during the Christmas break, and I would still go there tomorrow if possible. I love it, it deserves the hype, I can't find much against it. As long as you rent a car, book an accomodation that has many good reviews and a great rating, and you make sure to keep your bags secure, the place is really nothing short of Paradise on Earth.

Just reading a book and enjoing a coffee. Niiice.

I've been contemplating of booking a cheap flight to Milan, only with a backpack, rent a car, drive all the way to Como to a hotel near the lake and stay for a couple of nights. And, while there, rent a bike, pack a sandwich and a San Benedetto, pick a couple of trails and don't look back. Maybe you should, too.

Found a nice hotel in Bellagio that had breakfast included, Seta. There was also a bike renting shop nearby, Bike It! Bellagio, and the best thing about it was that they had a website which contained a few bike trail suggestions, so it was easy to start the trip with minimum preparation. Bellagio, as a town is quite nice, but there was a lot of construction going around and there weren't many places to eat or have a coffee, at least I did not find any. That was not on the convenient side, but the main topic of the trip was biking, so I forgave the shortcoming.

Bellagio - Como and back​

A quite classic trip to start with, not very hard, but not very easy, as it involved a few ups and downs along the way. The first checkpoint was the town of Nesso, as it was almost half way to Como and had a couple of highlights: a waterfall and a small bridge, Orrido di Nesso. It's worth a visit, don't mind the reviews on Google, you don't need to be a pro climber to take the stairs. There is also a small bar nearby, Bar la Cascata, to recharge the batteries with a authentic Italian espresso and croissant.

View of the Alps on Como	Boat on the Como Lake

Back on the road and Como was not that far away, and the ride was pleasant. Legend says that George Clooney owns a villa somewhere in the area, but I was not lucky enough to find it. Dropping by and enjoing one cup of his Nespresso was totally planned for the trip. Shame. Anyway, arrived in Como, beautiful as ever, and quite crowded for March. The weather was nice, though, so I guess that was the reason for such a large audience. But there was not enough time to loiter, as daylight was not going to last forever in order to bike back to Bellagio. There was a ferry to catch in Griante in order to make it back to Bellagio. This second part of this trip was not that pleasant, since it involved picking up the pace and avoid being on the road at night.

That being said, even with the faster pace, I did manage to enjoy the splendid scenery Como has to offer. Every corner of water, every boat, every villa on the shore, every bird in the sky. Everything was just perfectly part of the scenery and it makes sense why owning a property on the lake is such a good idea. Just reading a book and enjoing a coffee. Niiice.

Overall it was 65km ride and someone deserved some rest.

Griante - Villa del Balbianello - Porlezza and back​

Day 2, and surprisingly, not everything was hurting that much. For the second part of the trip, I chose a route that involved going north all the way to Lake Lugano. It started by taking the ferry from Bellagio to Griante, and a short visit to Villa del Balbianello, in order to start things slow. After enjoying the very well trimmed courtyard, it was time to hit the road again, and the route went north to Menaggio but before entering the city, the route would diverge from the main road, and it was uphill time baby. After this challenging part, the route went west.

Lago di Piano	Villa del Balbianello

The route was actually not that scenic to be honest, but it had a special bike lane all the way, which was much appreciated. However, there was nothing that special about the countryside, just farms, villages and a few cows here and there. Lago de Piano was actually beautiful, with it being next to the mountains, and it proved to be a good place to take a break. After taking a few pics of this gorgeous mountain lake, it was time to finish the first half of the route, in Porlezza. This very cozy town, just next to Lake Lugano, has a very nice boardwalk to enjoy the lake from, and right next to it, a gelato place. How thoughtful!

After a very needed break with coffee and icecream to lift the spirits back up, it was time to head back home. The route back was different until Menaggio, and this time, it was pure torture. It was a lot, and a lot, and a lot of uphill. I died at least 5 times until reaching Naggio, the place where the route would change from uphill to full speed downhill. Which was supposed to be good, right? Wrong, as the downhill part was so steep, and it involved so many turns, it proved that all the torture involved for reaching it proved to be not such a good investment. Ideally, folks, do this one the other way around.

Anyway, the route was shorter than the first one, only 47km, but I believe it was quite more challenging, due to all that uphill part. But eating icecream next to the Lake Lugano? Priceless.

Lecco​

Day 3, time to go back home. Since the flight was scheduled for the evening, Lecco was decided to become the third and last stop of the trip. The weather was a mix of sun and rain, which was not all bad, given the really great pictures I managed to take as a result of the shifting light. The town itself is quite nice to stop for half a day, but the best bits involve the scenery. The view towards Corni di Canzo is simply breathtaking, and I highly recommend going for a walk along the Como promenade and enjoy the views. Quite impressive, and, again, the sunlight really made it even better.

After going for a pizza (duuuh) at Pizzeria la Rosa and for a coffee (double duuh) at Coffee&Coffee, it was time to take the rental to the car lot, enjoy the airport van ride and the short trip back home. Biking on the Como proved to be an excellent choice for a weekend getaway, and there would be more such trips in the future for sure.

All stages in the software development lifecycle are important, but some stages are more important than others.

There are many important parts of the software development lifecycle. It's important to understand a business need, otherwise your feature won't be useful. It's important is to devise its requirements, create the designs, split the work and estimate it. Then comes the implementation, testing, delivering it to production and measuring its performance and usage through telemetry.

All stages in the software development lifecycle are important, but some some stages are more important than others. Is it true? Hard to say, maybe it depenends case by case. Are you a startup? A big tech company? Is there a similar product already on the market? There are many aspects to consider when you're prioritising.

We're not going to debate that here. Instead, I would like to advocate the importance of delivering the feature. If it's not being used by costumers, nothing else matters.

The Problem​

I was fixing an issue in Microsoft Teams related to a selection inside a search box. After fixing and testing it manually, my next step was to write a unit test using Jest and React Testing Library to make sure the issue won't surface again as a regression. The issue itself is not important, but the test looked, more or less, something like this:

test('should render the search box with the value selected', () => {
  const defaultValue = 'good morning'
  const {getByRole} = render(<SearchBox defaultValue={defaultValue} />)
  const searchBox = getByRole('textbox', {name: 'search for gifs'})

  expect(searchBox).toHaveFocus()
  expect(searchBox.selectionStart).toEqual(0)
  expect(searchBox.selectionEnd).toEqual(defaultValue.length)
})

The test is rendering our search box component, which we expect to be already focused and, if it has default text passed to it, to have it already selected, so the user can overwrite it in one go. The test looks fine, it's easy to understand, it covers the scenario, so we should be all done. In order to take it one step further, I asked myself if jest dom could have a convenience function to test this in one go, and also improve the readability. Something like this:

expect(searchBox).toHaveSelection(defaultValue)

Now, there's nothing wrong with the fist approach, but we can agree that the second one conveys the message better. After checking the functions available in VSCode, and noticing there's no helper expect function, I went to their repo with the thought of submitting a feature request, as I believe it could be a useful addition. Not only did the library already have a feature request, but it also had an open PR to add the function.

The feature request is, at the time of writing this article, almost 4 years old, and the PR is 3 years old. At first guess, I would expect that the changes introduced in the PR were not correct, or did not solve the problem one way or another. However, after checking the discussion and the code itself, the PR was actually in a very good state. It introduced the correct function, which covered all the required scenarios. It was able to check both input elements and their selection, and also random elements that could contain text, from paragraphs to divs. And for this second use case, the checks were mostly done by using the range and selection native JS objects, and covered the following:

1. whole elemenent was part of the selection.
2. the element containing the whole selection.
3. element contains part of the selection.

So, why wasn't this PR merged already? There was quite a lot of effort put into the changes, and users of jest-dom were not reaping the benefits. It made me curious enough to dive deeper.

The Solution​

It turned out that the code coverage target of 100% was not met, there was no documentation and no TypeScript support for the changes. Considering all the work that was done until that point, the rest seemed to be a piece of cake. What I did first was to fully understand requirements and the implementation.

We basically need to get the selection for the element we are asserting and return it. If our element is an input (not a checkout or a radio) or a textarea, we basically just return the selected text with element.value.toString().substring(element.selectionStart, element.selectionEnd).

The more challenging part is to get the selection of an element that's not an input. It could be a paragraph, a div, a span, doesn't matter, it should work in all cases. For this second case, there are actually 3 scenarios we need to consider. These scenarios need to account for one action: when user drags a selection by mouse, trackpad or keyboard (holding Shift). Our function has the element passed to it, so we get the document selection using element.ownerDocument.getSelection(). Afterwards, we need to check how much of that selection is included in element. We have 3 cases.

1. Whole element is inside the selection.

   • condition is selection.containsNode(element, false)
   • for example, our element is <span> that's contained in a <p> which got a partial or full selection, including the span.
   • we get the selection of the element with selectNodeContents(element) and return it.

2. Element contains the selection.

   • condition is element.contains(selection.anchorNode) && element.contains(selection.focusNode)
   • here we do nothing, since element fully contains selection, no need to change anything in the initial selection.

3. Element contains a partial selection

   • this means the selection either starts in the element, or ends in the element.
   • you can check in the source code from the link above the API used to get that partial selection that's relevant to the element, based on the 2 cases.

With the selection relative to the element received, we will use the already established template to build toHaveSelection and it's job done. However, as I ran the tests, there were a couple of Else branches that were not reached by the unit tests. I realised that with a bit of refactoring getSelection, it would be actually easier to test the changes, so I submitted a slightly different version for the partial selection condition.

Moreover, even though there was a complete coverage on the tests, I added a few more actions to the test cases, which were missing. 100% test coverage does not mean that you are testig your changes fully. However, less than 100% test coverage means most likely you are not fully testing. Consequently, aim for 100% coverage, but stay skeptical even with that percentage, since it's not a guarantee that your feature is fully tested.

OK, so we've written the tests, we refactored the code, we got full coverage. Since the repo is written in JS, we need to provide separate TS support, but luckily that was easy to do, given the templated previous functions alread written. Finally, I've written a README entry to serve as documentation, and this was actually based on the unit tests, given our function was actually going to be used as a unit test assertion.

Changes done, commited on my forked repo, and submitted a PR to jest-dom, asking the primary maintainer to review. I provided all the context, given the situation, so it would help speed up the process. A few days later, the PR was approved, merged, and included in jest-dom@6.6.0.

The Conclusion​

There is a lot of effort which involved so much hard work that is wasted if it's not delivered to your users. We see it all the time, in open source, in a small company that did not finish the product it aimed to deliver, in big tech where there are so many initiatives, hackathon projects and experimental features that do not reach their intended audience. It's probably why I chose to write this article. I want to emphasize that even if your work is not 100% ready to be delivered, that doesn't mean it shouldn't. It's better to aim to finish it 80% feature wise, deliver it and do the 20% later, than implement it 100% and shift focus at 97%. Deliver it at 80%. Hell, maybe even less. Who knows, maybe after reaching the costumers, you may realise that you don't need to do that 20%. Or that the rest of 20% after costumer feedback is now completely different from the initial 20% you initially imagined.

This does not mean that testing, accessibility, telemetry, performance monitoring and all other steps of the software development lifecycle are not important. Far from it. I'm not going to de-emphasize their importance. Just to point out that your effort is only useful when it's used by people, if it makes their life easier or their job less annoying.

Until next time, good luck in delivering great value to the world!

The Odeon of Herodes Atticus.

But anyway, here I was, Syntagma square, baby.

Ever had that urge to just go some place, do nothing but eat, chill, have a few walks with some coffee in between. Well, folks, how about some Athens in February? After enjoying Madrid and Malaga in January and December, I developed quite a passion for Mediterranean destinations during winter. All I wanted was some place that was still warm, not that crowded but still offering relevant stuff to do. And Athens really hit the nail in the head on this one.

Also, as a side note, notice that I'm writing about my February trip at the end of September. I'm quite behind on this little travel blog I have going on, and I decided to cut my articles short. I'll focus only on the good stuff, throw some of the best pictures and I'll wrap it up sooner than expected. I'm not going aiming to turn this blog into the Song of Ice and Fire.

Athens Food & Walks​

So, Athens. A very short flight from Bucharest. The train from the airport to the city center takes longer than the flight, and it's even less enjoyable. That says a lot considering I travelled low cost. But anyway, here I was, Syntagma square, baby. I took my bags and went by bus to Koukaki, this popular neighbourhood right next to old town, with more restaurants, bars and cats than you can count. So, what's so special about the place? Well, it's the chill place full of stuff to eat and drink that I was looking for. Found the local coffee shop, Caffeine Dealer, and realised that Espresso Freddo and Iced Flat Whites are a thing. Completely changed my life, this. As for eating, hmm, I would probably say Karimino, Neratzia and Bite Box are quite nice, with both brunchy things but also late meals.

Building on the Acropolis	View of Athens from the Acropolis

There's also a nice Turkish place just next to Koukaki, Cappadocia Grill Cafe, where you can enjoy a good old Adana Kebab or some chicken if you prefer lighter meat. However, probably the best place to get something to eat is the city center. There's Usurum Brunch & Cocktails, with one of the best pancakes in the world. There's Choureal, with, well, you can figure this one out. And Dope Roasting, with coffee and some quick bites that are also healthy. This place is also quite popular to work remotely. Right next to old town there's also Coffee Joint, where you can eat the most civilized omelette, have an orange juice and be on your way, no fuss included.

But, Silviu, Athens is a great cultural spot, one of the most relevant cities of the Antiquity, with so much to offer in terms of culture and history and much much more. Yeah, I've been to the Acropolis, it was nice, quite well preserved. Oh well, visiting sights and museums was not the point, so I did not bother that much. Anyway, there was another sight, sort of, that I visited as a recommendation from a friend, and that was the Stavros Niarchos Foundation Cultural Center. Apparently, some naval shipping tycoon built this place and, when I first saw it, I was not sure if I was still in Athens. It seemed like a building you would find more likely in Oslo. It's quite huge, with huge glass windows, and with greenery on top of it. Really fancy, I loved it. I also loved the walk from Koukaki to this place, all (ALL) the way throguh all (ALL) of Kallithea. It was refreshing to walk through a neighbourhood that does not probably make the top list of visiting.

View of the Acropolis from a nearby hill	The garden and a view of Stavros Niarchos

I had some other nice walks as well, like the ones in the Athens National Garden, next to the Syntagma square. Or the ones around Kallimármaro and Kolonaki. Overall, the city has that special something, you can feel it has personality and that it has been around for a while. And that brings me to the part where it's falling apart in many places, with so many ruined buildings, unkept streets and sidewalks. You can feel that, from the economical point of view, it's still struggling.

Even with the last downside, I loved my trip to Athens, it was exactly what I needed at the time, and I'm actually looking forward to return soon.

Hilly Landscape in the Village of Şimon.

...there's a lot going on with the attributes and the handlers and the ref and the other properties...

Let's assume that we have the following scenario. We have a custom hook that returns getter props, and we want to make sure that those getter props are called correctly. But, first things first:

What is a getter prop?

It's a function that gets returned from the custom hook, which is supposed to be called and its result used for some reason. Let's take the getInputProps getter prop from downshift:

import * as React from 'react'
import {useCombobox} from 'downshift'

const items = ['red', 'green', 'blue']

const {getInputProps} = useCombobox({
  items,
})

return (
  <div>
    <input {...getInputProps()} />
  </div>
)

The getInputProps result is an object with properties such as: aria-labelledby, aria-expanded, role, onChange, onClick etc. These properties are going to make our input more or less acting like a combobox. The combobox logic is kept inside the custom hook, the inputs are retrieved through the event handler functions (onClick, onChange) and the combobox related information is passed through the other attributes (aria-labelledby, aria-expanded). Of course, there are many more handlers and properties, but we are keeping it simple for now.

There's also the ref property that is going to be returned from getInputProps, and this is needed in order to allow useCombobox to access the input element and perform some custom .focus() actions when needed.

The Problem​

Given that there's a lot going on with the attributes and the handlers and the ref and the other properties, we want to make sure that the getInputProps getter function is called correctly.

• First of all, we want to make sure that it is called.
• Secondly, that is called on an <input> element, or in such a way that it has access to an <input> element.
• Thirdly, in case it is not called correctly, we want to inform the user through a console error and give them enough information to fix the getter function call.
• Moreover, we also want to show the console error in the development environment, not production. -In addition, we would like to show this error only on the first render, as we believe it's enough in terms of checks and informations.
• Last, but not least, we will also provide an escape hatch to avoid getting this error if the consumer just cannot call getInputProps properly on the first render.
  • We are going to document this escape hatch and make sure the consumer knows why we are adding it. Ideally, if a consumer will use the escape hatch, they are aware how getInputProps works, how it should be called, and if they, for some reason, cannot call it on first render (using a Portal for example), they will use the escape hatch to avoid the error, but they will test their implementation to make sure that it works as it would by calling getInputProps normally.

The Solution​

Inside the getInputProps function we return, we would like to have a mechanism that checks whether the function is called withing the right conditions. We can do so with a function to which we supply the call parameters. This function will be called at render time, since getInputProps is called on render time. The actual check happens after the first render, so we will involve a React.useEffect hook. After a bit of thinking, the solution is actually simple: a custom React hook that will keep call information inside a React ref. This call information will be supplied by a function which we will return from the hook. The returned function will store the call information inside that ref. And inside the effect function, we will perform the check and show the errors if needed.

The Tests​

We actually have a good and simple solution in mind, so let's see what do we actually expect from this solution.

• we want an error displayed when getInputProps is not called.
• we want an error displayed if getInputProps is not called with a ref pointing to an element.
• we don't want an error displayed if getInputProps is not called on subsequent renders.
• we don't want an error displayed if getInputProps is called correctly.
• we don't want an error displayed if we use the escape hatch provided and getInputProps is not called with a ref pointing to an element.

We will use React Testing Library renderHook and together with Jest, we will set up our tests suite.

describe('non production errors', () => {
  beforeAll(() => {
    jest.spyOn(console, 'error').mockImplementation(() => {})
  })

  afterAll(() => {
    jest.restoreAllMocks()
  })

  test('will be displayed if getInputProps is not called', () => {
    renderHook(() => {
      // we just render the hook, we don't call getInputProps.
      useCombobox({items})
    })

    expect(console.error.mock.calls[0][0]).toMatchInlineSnapshot(
      `downshift: You forgot to call the getInputProps getter function on your component / element.`,
    )
  })

  test('will be displayed if element ref is not set and suppressRefError is false', () => {
    renderHook(() => {
      const {getInputProps} = useCombobox({
        items,
      })

      getInputProps()
    })

    expect(console.error.mock.calls[0][0]).toMatchInlineSnapshot(
      `downshift: The ref prop "ref" from getInputProps was not applied correctly on your element.`,
    )
  })

  test('will not be displayed if getInputProps is not called on subsequent renders', () => {
    let firstRender = true
    const {rerender} = renderHook(() => {
      const {getInputProps} = useCombobox({
        items,
      })

      if (firstRender) {
        firstRender = false
        getInputProps({}, {suppressRefError: true})
      }
    })

    rerender()

    expect(console.error).not.toHaveBeenCalled()
  })

  test('will not be displayed if called with a correct ref', () => {
    // we supply a mock ref function to getInputProps.
    const refFn = jest.fn()
    const inputNode = {}

    renderHook(() => {
      const {getInputProps} = useCombobox({
        items,
      })

      // getInputProps returns a ref function which will make the element
      // usable both outside and inside useCombobox.
      const {ref} = getInputProps({
        ref: refFn,
      })

      // we call the final ref function received with a dummy node.
      ref(inputNode)
    })

    expect(console.error).not.toHaveBeenCalled()
  })

  test('will not be displayed if element ref is not set and suppressRefError is true', () => {
    renderHook(() => {
      const {getInputProps} = useCombobox({
        items,
      })

      getInputProps({}, {suppressRefError: true})
    })

    expect(console.error).not.toHaveBeenCalled()
  })
})

The tests are quite self explanatory given our 5 expected use cases. For now, they will obviously fail, and we will consider our job done once we write the implementation and the tests are green.

The Implementation​

To recap, the getter prop is called on render, so we would like our check to be performed after the render. We will store the call information inside a React ref, and we will check it using a React useEffect. Since we need our check to be performed in development mode, not production, we will define the custom hook like this:

let useGetterPropsCalledChecker = () => {}

if (process.env.NODE_ENV !== 'production') {
  useGetterPropsCalledChecker = () => {
    // the actual implementation.
  }
}

First and foremost, we would like to set up our ref object that we will use for the check.

if (process.env.NODE_ENV !== 'production') {
  useGetterPropsCalledChecker = (...propKeys) => {
    const getterPropsCalledRef = useRef(
      propKeys.reduce((acc, propKey) => {
        acc[propKey] = {}

        return acc
      }, {}),
    )
  }
}

And we will call this hook inside useCombobox like this:

useGetterPropsCalledChecker(
  'getInputProps',
  'getToggleButtonProps',
  'getMenuProps',
)

Notice that we will most definitely want the hook to check that other getter props are called correctly as well. We are going to stick to getInputProps here purely for explanatory purposes. Anyway, for each prop key we pass to the hook, we will create an empty object container inside the ref. We add this empty object as we want, during our checking phase, to be able to tell if the getter prop with that prop name was not called. We cannot perform this check if we do not store any initial information about the getter props. What prop keys should we actually check, right?

Next, we want to give the consumer, which is the getter prop function, to be able to store the call information. For that, we will return a function from the hook, which stores this information within the ref.

if (process.env.NODE_ENV !== 'production') {
  useGetterPropsCalledChecker = (...propKeys) => {
    const getterPropsCalledRef = useRef(
      propKeys.reduce((acc, propKey) => {
        acc[propKey] = {}

        return acc
      }, {}),
    )
  }

  const setGetterPropCallInfo = useCallback(
    (propKey, suppressRefError, refKey, elementRef) => {
      getterPropsCalledRef.current[propKey] = {
        suppressRefError,
        refKey,
        elementRef,
      }
    },
    [],
  )

  return setGetterPropCallInfo
}

And the usage within getInputProps is going to be something like this:

// this is going to end up on the input element via getInputProps
const inputRef = React.useRef(null)

const getInputProps = useCallback(
  ({refKey = 'ref', ref, ...rest} = {}, {suppressRefError = false} = {}) => {
    setGetterPropCallInfo('getInputProps', suppressRefError, refKey, inputRef)

    // rest of the logic

    return {
      [refKey]: mergeRefsUtil(ref, inputNode => {
        inputRef.current = inputNode
      }),
      // the rest of the attributes and handlers that will end on the input
    }
  },
)

In case the above ref logic is not clear, it ensures that all ref objects have access to the same input element. We need the input ref in useCombobox. The consumer might also need the input ref for some additional logic, hence the merge of these ref objects and passing the merged object to the <input> element. Also, suppressRefError is the escape hatch we talked about previously.

Now the checking part. We have the initial object created for each getter prop on render phase, when useGetterPropsCalledChecker is called. We have the call information stored when getInputProps is called, also on render phase. Now we have to check if the function is called correctly, on first render only, so we add a React useEffect hook inside our custom hook:

useEffect(() => {
  Object.keys(getterPropsCalledRef.current).forEach(propKey => {
    const propCallInfo = getterPropsCalledRef.current[propKey]

    if (!Object.keys(propCallInfo).length) {
      // eslint-disable-next-line no-console
      console.error(
        `downshift: You forgot to call the ${propKey} getter function on your component / element.`,
      )
      return
    }
  })
})

Our first test should pass. If the object is empty, then it means that we did not call the getter prop at all, so we show an error. If the getter prop is actually called, then we need to check if the element exists, which means that the getter prop is called correctly on an element.

useEffect(() => {
  Object.keys(getterPropsCalledRef.current).forEach(propKey => {
    const propCallInfo = getterPropsCalledRef.current[propKey]

    if (!Object.keys(propCallInfo).length) {
      // eslint-disable-next-line no-console
      console.error(
        `downshift: You forgot to call the ${propKey} getter function on your component / element.`,
      )
      return
    }

    const {refKey, elementRef} = propCallInfo

    if (!elementRef?.current) {
      // eslint-disable-next-line no-console
      console.error(
        `downshift: The ref prop "${refKey}" from ${propKey} was not applied correctly on your element.`,
      )
    }
  })
})

Our second test should now pass. The element check is, sure, not ideal, since we're not checking for an actual HTML input element, but let's say it suffices for now. The fourth test which checks that there is no error logged was passing already, but now with the actual element check, we make sure that, when it's passing, it does so for the right reason.

To fix the second test, we need our hook to be called only once, on first render, so we add [] as the second parameter to useEffect.

And to fix the fifth test, which checks the escape hatch, we will also involve the suppressRefError parameter from the call information. Our final implementation will look like this.

if (process.env.NODE_ENV !== 'production') {
  useGetterPropsCalledChecker = (...propKeys) => {
    const getterPropsCalledRef = useRef(
      propKeys.reduce((acc, propKey) => {
        acc[propKey] = {}

        return acc
      }, {}),
    )

    useEffect(() => {
      Object.keys(getterPropsCalledRef.current).forEach(propKey => {
        const propCallInfo = getterPropsCalledRef.current[propKey]

        if (!Object.keys(propCallInfo).length) {
          // eslint-disable-next-line no-console
          console.error(
            `downshift: You forgot to call the ${propKey} getter function on your component / element.`,
          )
          return
        }

        const {suppressRefError, refKey, elementRef} = propCallInfo

        if (suppressRefError) {
          return
        }

        if (!elementRef?.current) {
          // eslint-disable-next-line no-console
          console.error(
            `downshift: The ref prop "${refKey}" from ${propKey} was not applied correctly on your element.`,
          )
        }
      })
    }, [])

    const setGetterPropCallInfo = useCallback(
      (propKey, suppressRefError, refKey, elementRef) => {
        getterPropsCalledRef.current[propKey] = {
          suppressRefError,
          refKey,
          elementRef,
        }
      },
      [],
    )

    return setGetterPropCallInfo
  }
}

Recap​

Basically, we initialize an empty object for each getter prop we want to check, using the getterPropsCalledRef React ref object. Then we return the setGetterPropCallInfo function that will store information for each getter function when called. Finally, inside the useEffect function, for each getter prop, we get the call info from the ref, we check for an empty object and show the getter function not getting called error. In case we our object in not empty, we get the call information, and do nothing if suppressRefError is true. Otherwise, we check the actual element ref and show an error if it's falsy.

We may go even further with the tests and check if the hook is actually an empty object on production environments, but at this point I'm not sure if it's possible to implement such a test, or if it's even worth it. Bottom line is that, using this custom hook, we are able to perform the function getting called check, or other checks as well, in order to make sure our consumers are doing the right thing and the solution we ship works for them.

If you think you know already the meaning of tasteful luxury, visit this place and reset your standards.

Today, damas y caballeros, we stay in beautiful Spain, but this time we leave the sunny South for Mardrid, the capital of football, culture and, well, Spain. It was a long time coming, and I was super excited to start 2024 travelling season with this one. I had high expectations, given the reviews I received from my friends, and, honestly, I was still amazed by what the city had to offer.

Royal Palace and Surroundings​

If you like your trips cultural, you're in the right place. We started the trip with the Royal Palace of Madrid, and, Dios mio, what a start. I've seen palaces and museum, and quite plenty, until that point, but the Royal Palace of Madrid exceeded my expectation by far. If you think you know already the meaning of tasteful luxury, visit this place and reset your standards. Every single piece of furniture, tapestry, design and artwork was exactly where it was supposed to be, and the level of detail for every single one of them was incredible, from engravings to finishing touches. They don't let you take pictures inside, and it's really a shame, as it's probably one of the most exquisite places you could feast your eyes upon.

Catedral de la Almueda	Room inside Royal Palace of Madrid

We left the palace exactly when it was closing time, so there was no more time left to visit the Almueda Cathedral unfortunately, but we did enjoy a very nice walk around Plaza de la Almeria, and took some pictures with Campo del Moro in the background. Quite close to the palace there's the Mercado de San Miguel, which is quite a great place to stop by for an hour or two and enjoy some empanadas and cervejas. Back to the hotel and ready for another day. We stayed at the Room Mate Alba Hotel, which is located in the city center, but in a very quiet area, and the hotel itself is quite nice. Between the Mercado and the hotel we passed through Plaza Mayor, which is another landmark worth checking out, given its surrounding buildings, coffee shops and vibrant atmosphere.

Prado Museum, El Rotiro Park, Food and Coffee​

Prado Museum is probably a must go if you're going to Madrid, and for good reason, since it boasts such a vast collection of art pieces from artists such as Francisco Goya and Diego Velazquez. You could spend a few days here without a doubt, but we also had some other places in mind so we were happy to be done in just a few hours. Outside, there's the beautiful park El Retiro, with its signature pond decorated with the colonnades of the Alfonso XII monument. It was a great walk to bask in the sun and forget that it's the middle of January for a few hours. Right next to the park there's also the botanical garden, which would have been a better pick in any other season, but we still enjoyed the impressive collection of bonsai trees.

After leaving the botanical garden we went for a stroll through the upscale Goya neighbourhood. It's nice over here. All buildings are very, very well maintained, and they are simply beautiful and elegant. The city is just amazing, I don't think I encountered anything that was either bad or at least "could be better". Maybe the coffee was not as great as in other places, but there were some coffee shops that were quite good, for instance the Norah Coffee & Brunch in Goya. Don't forget to try the sweets. Another great option is Pascal Specialty Coffee & Brunch, which was closer to the hotel, and features a brunch selection more on the healthy side. If the coffee could have been better, the food was actually amazing. Spain has great food, without a doubt, and other places we could recommend in Madrid are Los Porfiados, for a cozy dinner, or Fiaschetteria La Saletta, if you crave Italian. Other coffee options worth mentioning are Alchemy and Dale.

Santiago Bernabeu, Sorolla Museum and Gran Via​

I'm not much into football, but when I watch it's most probably a Real Madrid game, either in La Liga or Champions League. Visiting the Santiago Bernabeu was something I really wanted to do, especially now with the updates it received. From the outside it's quite a piece of art, I love the facade with its gray shiny blades. On the inside, well, it's huge there are lots of big screens everywhere and a retractable roof, letting you know that it's proudly representing the 21st century. We could not enter the locker rooms, which was quite a shame, but at least we saw the hall of trophies, and there are a lot of them. This team knows what winning is about.

Santiago Bernabeu Stadium	Gran Via

After we left the stadium we went back towards the city center by foot and we stopped at the Sorolla Museum on the way. It's actually the former house and studio of Joaquin Sorolla, who travelled throughout Spain in order to create a considerable collection of paintings. The art pieces inside the museum are organised in a timeline manner, so we could follow along his interests and favorite places as he aged, from his home city of Valencia, to the Spanish countryside and the capital of Madrid, where he was very passionate about his garden. The garden itself is a great place to relax on a bench, looking at the pond and enjoying the shade of the trees.

The last but not least landmark I would like to mention is the Gran Via, and I would not miss it especially during the night, when I believe it really shines. Both the buildings, the landmarks and the street itself are spoiled by huge amount of light and it's a great way to end the day with a stroll to the shops and just enjyoing the vibrant heart of this otherwise amazing city. It's trully a great city, and probably one of my favorites so far. It's amazingly beautiful, it does not seem to be that crowded, the people are friendly, the food is great, the weather is pleasant and there are so many things to do. I would definitely come back here one day, definitely on a Real Madrid match day. Looking forward, hasta luego!

View of Malaga from the Mirador de Gibralfaro.

Truth be told, I don't mind palm trees with Christmas lights. I could live with that.

Finally, the South of Spain. It took a while to get here, but here we are. It's December, sure, but not in Malaga though. Good thing I brought a couple of T-shirts, otherwise it would have been a tough time. Christmas decorations while the weather's so good is just out of this world. Truth be told, I don't mind palm trees with Christmas lights. I could live with that.

So far so good. It turned out that going to Malaga at the beginning of December is a great idea. That was the good part. The bad part was that also half of Spain thought it was a good idea, and the place was packed with visitors. I believe they also had a day off during the week we chose to visit, and everyone took advantage of it. Our apartment was in the center (Be Mate Malaga Centro, great place, check it out) and we had to park somewhere, but, really, there was absolutely no place to park a bicycle, yet alone a car. We finally found a payed multi level car park nearby, barely. Inside it, we found an empty spot on the last floor. Lucky us.

Malaga by Day​

I believed that using a rental car was the way to go, since we planned to visit at least some other town besides Malaga, but we did not leave the city eventually. However, the car was cheap to hire, and since I used it only to drive from the airport and back, I did not even bother to refuel. Anyway, we got to our apartment, super nice, way above what we got in Naples or Catania. Yes, it was a touch more expensive, but we got a lot for our money. Totally recommend the place, it was spacious, modernly furnished, right in the city center, but in a very quiet area.

Now the city itself. The historical city center is, I would say, a pretty standard Spanish city, and that's a very good thing. It's clean, it's very well maintained, the buildings are superb, and the amount of restaurants and coffee shops is insane. Spain does not offer the best coffee in the world, not even in the specialty coffee shops. It's not bad, by any means, but certainly not the best. On the other hand, the food, well, that's something else. From the standard brunch toasts, Benedicts and avocados to the seafood, meats and deserts, the food in Spain is just glorious. I think Portugal still tops it up, but Spain is definitely top 3 in my book. Definitely check out Next Level Specialty coffee, and you must, absolutely must, get the French Toast: toasted bread with cream, bananas, strawberries, blueberries and honey. Combined: magic.

Walkway to Alcazaba	Catedral de la Encarnacion

Obviously, there are some sights to absolutely deserve a visit. But just walking through the city center is pleasant enough, while going to the stores, getting ice cream, the usual stuff. As we strolled around, we got to the Catedral de la Encarnacion, which is Malaga's main church, and it's imposing both on the outside and on the inside. Definitely worth paying for the entrance. From there, the Alcazaba is just at "a stick throw" distance, and it's the main atraction of the city. For good reason, to be sure. The castle itself is very well preserved, and they are obviously very proud of their monument. And walking through the courtyards is a great experience, especially because of the many beautiful gardens and beautiful architecture. And, of course, the views over Malaga are simply gorgeous.

Right next to the Alcazaba there's the Gibralfaro Castle, and since we visited Alcazaba, we might as well do both simultaneously. Gibralfaro is not as special as the Alcazaba, but it has better views, especially from the Mirador de Gibralfaro. We could not see the Malagueta from there, due to the buildings around the Plaza de Toros. But we did, of course, enjoyed a great view over the stadium for the bullfighting shows.

Another point of interest is the Malaga Museum, which definitely has a lot to offer. I found the painints from Moreno Villa particularly interesting, and there should be enough art for everybody. Actually, I think the Spanish museums are the best I visited so far, so if art is your thing, make Spain your priority. I enjoyed museums not only in Malaga, but also Barcelona, Madrid and Zaragoza. One thing that's actually a bit not so great is the fact that, when it's 15 minutes to closing time, they smiply kick you out, without any sign of politeness. It happened to us in Malaga and also in Madrid, and the fact that they insist for you to leave is just, well, not great. On the bright side though, once you exit the Malaga museum, there's a very nice terrace with palm trees that screams Instagram and Vice City, so we definitely took a few pics with the palm trees at dusk.

Malaga by night​

Remember the part when I mentioned half of Spain was in Malaga for the weekend? That was not immediately obvious by day, save for the parking situation. However, by night, it was a completely different story. The whole city center, from the Plaza del Constitution, all the way down the Marques de Larios and towards Malaga park, including it, was so crowded it was just impossible to move. It was quite scary at times since I was not used to these kinds of crowds, but apparently, in Spain, it's completely normal. Nobody was even remotely mad about the whole thing.

Every person in the crowd was happy, everyone was singing, there was a smile on each and everybody's face, and I realised just how happy people are over there. In lived in Bucharest and Prague all my life, and I am mostly used to seeing gloomy faces that were quick to snap and constantly one small second away from getting angry. And it felt good to see happiness, just randomly manifesting itself on the street.

Probably the holiday also helped to create all this joie de vivre, and we were lucky enough to be in the city center when they blasted music through the speakers, along with a light show using the Christmas decorations. Everyone, obviously, knew the songs, so they were singing along. It was absolutely amazing, probably one of the best feelings I had for a moment, and I will always remember Malaga for that show and for how it made me feel.

One evening we also met with a couple of friends who happened to be around Malaga at that time, and we went for a walk towards the Malagueta and then back to the city center, where we went to a ramen place. I'm not a fan of the soup, but luckily they also served sushi, so it worked out well for me as well.

Since I am also watching games in La Liga from time to time, I know that Malaga has a very famous football team. Consequently, I could not leave before going for a walk to the La Rosaleda stadium. Sadly, it was already dark outside, and could not see much of the stadium, and since it was already evening, visiting it on the outside was not possible either. It did not seem to be as grand as the Bernabeu or the New Camp, but I was happy to see it anyway, as I'm also a fan of its name, La Rosaleda.

Wrapping up​

It was a very short trip, and I'm quite OK with the fact that we did not go other places we planned to, like the Caminito del Rey or Granada, but this leaves us with the opportunity to go back and make up for it. And, most probably, I will be back in Spain multiple times from now on, given its rich history, great Western architecture and Moorish influences, incredible museums, incredible food and good enough coffee. Next on the list was, obviously, Madrid, for a strong 2024 start in the travelling department.
