I’ve been offline on most socials for a while. X became too toxic and drained all the joy out of it. Opened Bluesky again and this still feels so much nicer ❤️ How’s everyone doing here? Anyone working on something cool?

Very close to wrapping up a BIG new release for the FrontendFYI Playgrounds — Juuuust need to do some responsive fixes 🫠

When did they add the ability to advance time with Stripe Subscriptions in test mode? This is gold! 🔥

Let's see if Codex is capable of doing something a bit more challenging. Touching quite some files, involving quite a few lines of code.

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 05/06/2025

Exploring OpenAI's Codex a bit. First thing it complains about is me leaving in a placeholder readme and fixing that for me. I like it. It's super accurate too.

Now @gsap-greensock.bsky.social is free, that also means their amazing and versatile Split Text plugin is free too 🔥 Just experimented with it to see how well it integrates with @motion.dev – and I gotta say, this works GREAT! Check the link to the playground below.

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 24/04/2025

The Frontend FYI playgrounds got a visual refresh — better spacing, clearer UI, and just a smoother place to build. No feature changes, just thoughtful tweaks that make it feel right.

Help. Second day of not being productive, fighting Prisma 😭

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 10/04/2025

What a day 🤯 This morning suddenly Prisma couldn't find my env vars anymore, nothing would fix it. Eventually got it fixed by upgrading Prisma. That was a major upgrade though, having some breaking changes. Now that's fixed Turbo is running out of memory during build 😭

Just updated the playgrounds' console to also show logs, instead of only errors. What was I thinking when first building this, showing only errors. Of course you need all these 'here' 'here' 'here' logs 😉 What else would you like to see added?

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 04/04/2025

🔥 Wrapping up the latest Motion course module, and I just couldn't wait to share this! We’re diving deep into the animate() function to build advanced, multi-element animations. This example? Just the beginning of what you'll create! Can't wait to see how you'll use this!

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 19/03/2025

Just fixed quite an important bug in my playgrounds 🤯 What do you think happens here when the user is not logged in (user = undefined)?

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 11/03/2025

I like these big carousels on pages. But what I don't get is why the engineers took the lazy route here and just added a scrollbar there? On windows this will look even uglier 🤯

Tried to add a simple credits system. Realized the whole account page was trash. Here's the diff from my "quick fix." Ever started with a small feature, only to end up rewriting half the app? 😅

110

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 07/03/2025

The old account page? Definitely an MVP — and it's been bugging me ever since. With more courses and recipes on the way, it’s time for a real dashboard at Frontend FYI. Oh — and those credits? Soon you’ll be able to unlock content without PRO 👀

Lol, thank you Warp. One notification apparently wasn't enough to get me to upgrade

Last weekend YouTube suggested this great video by Kevin Leneway Happened to play with MCP last week too, his setup was therefore extra intriguing. Definitely watch this video and others on his channel! My experience in the next post. youtu.be/gXmakVsIbF0

Now we've finally ended up at the more complex animations chapter, it is time to start diving into animation sequences. I took inspiration for this lesson from from the Dropbox Brand Guidelines you find here; brand.dropbox.com/logo Beautiful animations on that page!

Today I learned about the Model Context Protocol. As I understand it, a standardised way to make LLMs interact with anything, we write the MCP middle layer (in for example TypeScript), to talk to a Database, Google Maps, your bookkeeping etc. EXCITING 🤯 modelcontextprotocol.io/quickstart/...

Finally got around to adding a Github Login / Signup. Isn't it a must for a developer focussed platform? I guess so.

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 07/02/2025

I love to get comments like these🔥 They are what keep me going! I KNOW my content is awesome, yet it's also so hard to make (enough) money out of content creation as a small creator, as I try to explain to Samir in my comment. Would love to hear you thoughts about this too 🥰

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 06/02/2025

Just gave my PRO page a much-needed update! 🚀 I realized it never fully captured my vision — PRO isn’t just a single course, it’s a growing resource packed with value. This update finally shows that. Check it out, and if you’re on the fence, now’s the time to join PRO! 🔥

Moments like these make me really surprised by today's capabilities of AI. Its able to take a very basic instruction and ugly code from a screenshot (!!), and turn it into something that works perfectly🤯 Sure it's not a 1-1 representation, but that also wasn't what I asked for

020

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 01/02/2025

Version two. Muuuuch more professional 😏 Only need to create a logo which I can add onto the coffee bag as well.

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 31/01/2025

First steps towards experimenting with a different type of content😏 Making frontend content is such a serious business. This is gonna be fun on a different level Not sure when I'll be able to create a first video. This was just a fun first experiment. Have a great weekend!

110

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 31/01/2025

Alright, gonna press the button 🤞 Quite the journey.. Still not entirely sure I didn't miss anything, but this needs to be done now. Took me far more time than I hoped. Let me know if you spot anything that looks off please. Playgrounds are still on V3 for now.

040

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 31/01/2025

Using Tailwind V4 with Astro? Be aware that if you have any unique classes inside a `client:only` component, these won't get bundled into your CSS file. Thus you might end up with some broken styles. The team is aware and working hard on getting a fix for this asap ❤️

030

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 31/01/2025

Considering my life choices for choosing Tailwind for my Motion course: Dilemma: Should I update my playgrounds to V4, meaning I need to prompt for all these breaking changes in old save states of users – or should exercises stay on V3 (bad idea too) Plus videos show V3 too!😫

250

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 31/01/2025

Possible UI direction for my next course. All about CSS — with AND without Tailwind. We’ll be building a beautiful page from A-Z.

140

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 30/01/2025

Tailwind V4 MIGHT break (Framer) Motion animations 🚨 V4 uses individual transform properties. Meaning if you set a initial state on a transform via a Tailwind class, TW uses `translate`, and Motion uses `transform`. Ending up in having the translation applied twice! 🤯👇

040

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 30/01/2025

Today I learned that CSS Individual Transform Properties actually get ADDED UP with regular `transform` 🤯 Causing my upgrade to TailwindV4 to break many of my Motion animations. I'm still not sure if this is intended or not.. Watch the video here: youtu.be/tdip011nNGk

I'm so much looking forward to use more 'normal css' with TailwindV4. Been trying to upgrade since the early alphas – sadly I ran into multiple issues. After lots of trial and error I feel I'm really close now, just need to build my own alternative for the typography plugin😅🤞

Who said css isn’t a real programming language?! 🤓 Google is working on a first test implementation of if-statements in CSS. What do you think about it? Google’s progress: groups.google.com/a/chromium.... CSSWG Discussion: github.com/w3c/csswg-d...

A while back, I added the ‘by Jeroen’ suffix to my YouTube channel. Today, I took it a step further and replaced the logo with a picture of myself. I’ve realized I’m much more drawn to people than brands—and I want my work to reflect that too. What do you think?

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 21/01/2025

Swapped my 'latest videos' section with a neat scrolling carousel showing the vastness of my content 🤯 Perhaps not the easiest to find the latest content, but it does show how much great content is already out there – which is what the intention of the homepage is imo 🔥
