Downloading files in Remix with useFetcher hook
Handling file downloads is a common requirement in web apps, whether it’s for exporting data as CSVs or generating PDF reports. Recently, I developed a feature that enables users to download files after specific interactions, like clicking a button to generate a report. In this article, I’ll explore practical approaches to implementing file downloads in Remix.
Summer update
Its been a while since I posted some personal updates. We're in the middle of summer, so I thought it would be a good time to share some of what's been going on lately.

Highlights from a visit to Tenerife
Last year in December, I had a chance to travel to Tenerife for about a week. It's my 3rd visit to this place, and I still find this place fascinating. I had no particular plans for this trip, so I just went with the flow and explored the island.

For the last 4 years, Gatsby has been the engine behind this blog. But from today onwards, you're browsing a page built with Astro, a web framework that powers fast content sites. Here's why I decided to move away from Gatsby and what I like about Astro.
A summer trip to Windermere, Lake District
Earlier in August, I had the pleasure of spending a week-long vacation in Windermere. With group of friends we've enjoyed time off, exploring this area of Lake District. It was a relaxing break and an opportunity to visit some new places.
Peak District Highlights
While organising my photos library, I found some photos from a trip to Peak District I did some time ago last year. I realised I never published them, and since I immensely enjoyed the views there, I hope you may too.
7 things to see on The Seven Sisters Walk
The Seven Sisters Walk in Sussex is one of the most picturesque ones you can find near London. It stretches from Seaford to Eastbourne, traversing a spectacular coastal path that offers magnificent views of the chalk sea cliffs on the English Channel coast.
A Trip to Cheddar Gorge
A week ago, with a group of hiking friends, we went for a short getaway to Cheddar Gorge. This photo story is a record from a delightful weekend we spent there, visiting the gorge and some areas around.
Dorset and Devon
Earlier this month, I had the opportunity to spend a few days travelling around the southwest of England. I'd been awaiting this trip for quite some time, as it was the first getaway for this season.
Wendover Woods Hike
Last weekend, Sunday, I strolled on yet another casual hike hosted by the Outdooraholics group. Wandering through the Chiltern Hills Area of Outstanding Natural Beauty offered an experience of surrounding woodlands and some great, panoramic views from the hills.
Highlights from India
I recently had the opportunity to visit India for two weeks in October. It was my first time travelling to Asia. I didn't know what to expect, but I was excited to explore a new country, experience new things and visit new places.
Richmond Park Photowalk
Richmond Park is one of my favourite places in London. And it's funny when you think about it because when you're there, you feel like you're actually far away from the big city.
Hampta Pass Trek
Last month, in October, I visited India for the first time. One of the main highlights of this journey was a 4-day long trek in Himalayas Mountains on the trail called Hampta Pass.
Hiking Eridge and Harrisons's Rocks
Summer is not officially over yet, and I've managed to salvage last sunny weekend to again join Outdooraholics for another hike. Navigating paths at the border of East Sussex and Kent counties, I enjoyed the green and calm atmosphere of woods and stunning crags of Harrison's Rocks.
The Seven Sisters Hike
Seeing rain predictions for upcoming days, I feared of possibility that the last warm weekend of summer was just passing by! So, almost at the last minute joined the Seven Sister hike on the sunny, southern coast of Britain.
Hiking the Rolling Hills of Hertfordshire
Just a week later, after my last hike, I joined another one with the Outdooraholics group. This time the hike called for exploration of Hertfordshire: a walk through the western area of Hitchin and the North Easterly ridge of Chiltern Hill.
Hiking Sussex Weald, Ardingly Reservoir and the Ouse Valley viaduct
This weekend, on Saturday, I had a chance to enjoy another hike with the Outdooraholics group. This time explored West Sussex, walking through some woods, a few gentle hills and passing under Ouse Valley Viaduct. It was a pleasant and relaxing experience on this beautiful summer day.
Iceland Highlights - Part Five
With this tempo of updates, I will probably not finish my Iceland series soon. But I keep trying. In this part, I cover the next part of the trip around Iceland's Ring Road, driving further east, visiting beautiful beaches, a Viking village, a glacier lagoon and more stunning views.
Sunset and sunrise at the Beacons Horseshoe
Only a few weeks later, after my long hike in Brecon Beacons Mountains, I returned to the same mountains visiting the most spectacular parts, known as the Beacons Horseshoe.
Hiking in Brecon Beacons Mountains
At the beginning of June (the long weekend of Queen's Platinum Jubilee), I left London for a 4-day hiking excursion at Brecon Beacons Mountains in Wales. I planned to hike parts of The Beacons Way - a long-distance walking path running the length of the Brecon Beacons National Park. I didn't have enough time to cover the entire distance, but it was still an exciting journey.
Spring training update
I can finally feel that I'm breaking free from the misery mixture of being unmotivated, lazy and just feeling low. It is still early, only roughly two months of training, but I can already feel some changes.
Iceland Highlights - Part Four
Continuing my Iceland series, I'm ready to share the next part of the journey from my travel. We continue east along Ring Road, visiting some cliffs where Puffins are nesting and then some more mountains and glaciers views.
Iceland Highlights - Part Three
Welcome to the third part of my Iceland highlights. This blogpost series is a recap of my trip from the summer of 2021. We continue along the south coast road visiting more beautiful waterfalls, some glaciers, and a crashed plane in this particular part.
Iceland Highlights - Part Two
I started last month with a review of my photos from the previous year's Iceland trip, and I've shared some bits from the first days of the travel highlighting the famous Golden Circle route. But Iceland is so much more. Our journey was planned often on the go, driven by the exciting spots along the Ring Road and the booked accommodation.
My Iceland Highlights - Part One
I wrote and published earlier two photo stories from my trip to Iceland in 2021. Still, they were only about Fagradalsfjall volcano, and I have so much more to share from that travel.
The Long Man of Wilmington hike
Going for a countryside walk on weekend is a great way to spend time. This Saturday I went for another group hike, this time from Berwick to Eastbourne, with the highlight of visiting The Long Man of Wilmington a human figure carved on the slopes of Windover Hill near Wilmington, East Sussex, England.
Leith Hill hike
On Easter Sunday, I spent some quality time enjoying a bit challenging yet very rewarding hike in the area of Leith Hill in Surrey. The weather was fantastic, and I had some opportunities to take some photos along the way.
How to access Remix route data in other routes
Nested routes are a neat concept of Remix framework. The idea is that segments of the URL path of the applications define the layouts and the data dependency of those layouts. In many use cases, your view could be a composition of multiple route levels, and you may end up with the need to access the data that was fetched in one of your parent (or child) routes.
Work from home
The erosion of the current working model was already happening slowly over the last decade. Still, the previous years of COVID-related lockdowns strongly accelerated the process. I'd argue this was a positive change!
Updates, updates
It has been almost six months since the last update. That's quite a long time. Especially for someone who claims to tell stories! I won't seek excuses to explain that. I was definitely lacking some engagement, creativity and inspiration. Some ongoing personal changes also contributed to this.
Clarity
I went for a run today, dragging my ass from sofa, out through the door on the evening streets of Hamburg. My motivation was low, my energy was low and I struggled to complete simple and familiar 5km loop route I often used to do here.
Return to the Fagradalsfjall volcano
If you've read my previous story about the Fagradalsfjall volcano you know that I didn't have much luck witnessing actual eruption. But the hike was a great experience anyway, so two weeks later, I've returned to the same place, took a slightly different path and went on planning to see the eruption.
Fagradalsfjall volcano and the lava fields of Geldingadalir
The Fagradalsfjall volcano was one of the key points of my trip to Iceland. I've visited the site twice, in the beginning, and towards the end of my journey. While I almost didn't see the eruption, I enjoyed the surreal landscape quite a lot. This photo story is a record of the hike.
Wake up!
It has been a long (winter) hibernation season. Way too long for me. My blog was stagnant for eight months, and I was stuck too. Not much happened, not much changed.
Moin, moin Hamburg!
It was a bit spontaneous decision, it happened quickly, it took almost 3 months of efforts, but here we are. We've finally completed our move to Hamburg, Germany!
