We did the same and never looked back.

coffee count: 3. bugs fixed: 1. bugs created: 2. net progress: vibes.

Hot take: the best accessibility fix is almost always "use the right HTML element". #heliostack

Reminder: you probably don’t need that state management library. URL + server state covers a lot. #opensource

reviewed a PR where the AI wrote the tests first. Honestly it was great.

optimistic UI is a UX feature, rollback handling is the engineering feature. #서울

Thread: I love when the database enforces the invariant so the app code doesn’t have to.

Reminder: finally moved our realtime updates to SSE. Simpler than websockets for 90% of cases. #nextjs

Small win today: server components finally clicked for me once I stopped thinking of them as "SSR".

Thread: I love when the database enforces the invariant so the app code doesn’t have to. #ai

Hot take: OKLCH makes building colour palettes feel like cheating. #webdev
