Hey, I never properly introduced myself, so let's start: I'm Melvyn, 23, and I've built a French developer community of 50K+ subs on YouTube. Looking to connect with more international people, so I'm switching to English-only posts here! I build a lot of projects: → saveit.now - bookmark tool → lumail.io - email newsletter → thumbfa.st - YouTube thumbnail generator Let's connect. Don't hesitate to DM me!

Real take : I want to move all my nextjs to full client side, vite and tanstack it geek so mich faster

Felix Rieseberg@felixrieseberg

A small ship I love: We made Claude.ai and our desktop apps meaningful faster this week. We moved our architecture from SSR to a static @vite_js & @tan_stack router setup that we can serve straight from workers at the edge. Time to first byte is down 65% at p75, prompts show up 50% sooner, navigation is snappier. We're not done (not even close!) but we care and we'll keep chipping away. Aiming to make Claude a little better every day.

@trevorlasn Sometime nextjs fail for no reason, I get it a lot of time. Timeout, loading that you need to refresh to have the page working this kind of stuff

Trevor I. Lasn@trevorlasn·4h

@melvynx Have you looked at the test setup? 34% failure rate is extremely unusual for Next.js in production. I've been shipping with 16 for months and my bottlenecks have always been database and external APIs, never the framework

This graph is quite insane. TanStack Start is: • 1.5 to 2 times faster than Next.js • Next.js actually fails 34% of requests for... nothing What is this? Wtf?

let's be honest: Yes, GPT-5.4 is smarter. Yes, it actually is; it's okay. But it's a boring model. It is limiting, lazy, and doesn't want to output my env when I explicitly ask for it. What is the purpose of this?

André Prado@andrehfp·4h

@melvynx so 99% of your day is coding or is it asking to show you env? because this will tell you which model to use

@wesbos I didn't "steal the chart from the thread" but actually searched it because I didn't remember who made it.

@melvynx This is a chart and you should link up Matteo’s thread

Matteo Collina@matteocollina

We benchmarked TanStack Start, React Router, and Next.js running the exact same eCommerce app at 1,000 req/s on AWS EKS. The results were eye-opening.

@melvynx In 2026, worrying about which platform to use is a waste of time IMO. There's so much more important work to do and things to build. Switching platforms and the whole stack is a weekend job. TRIVIAL.

Opus 4.6 for thinking, brainstorming, and planning. Composer 2 for implementation, code really fast. GPT 5.4 in the trash.

Cursor@cursor_ai

Composer 2 is now available in Cursor.

Want to create a Tanstack Start boilerplate with Convex for all my projects, this can be absolutely insane.

If your company doesn’t have a CLI, you should have failed at this point. Any agent can one-shot this in less than 10 minutes.

Just try Composer 2: → for new apps, it makes WAY cleaner and smarter code than Opus and Codex → makes reducers, respects clean code → respects the UI and features I ask for perfectly It's a good model. Really.
