Using React transitions for low priority text editor updates
5 minutes by Shane Friedman
React ProseMirror is fast for text editing but can slow down when multiple components use the same editor state. The article shows how React's Transition APIs can solve this by making some updates non-blocking. The main editor stays responsive while preview components update with a slight delay. However, this approach introduces risks with stale data that developers must carefully avoid.
Avoiding TanStack form pitfalls
5 minutes by Matt Huggins
Matt discovered validation errors weren't displaying despite the validation running in Tanstack Forms. The issue was a type system gap where synchronous validators accept async functions without TypeScript errors. When using async validation with sync validator options like onSubmit, the form rerenders before validation completes, hiding error messages. The solution is using async validator variants like onSubmitAsync instead.
