nuqs 2.5 - Debounce, Standard Schema, TanStack Router, Key isolation, and more
The type-safe search params state manager for React has just published a big release full of long-awaited features, bug fixes & improvements, including:
- Debounce: only send network requests once users stop typing in search inputs
- Standard Schema: connect validation & type inference to external tools (eg: tRPC)
- Key isolation: only re-render components when their part of the URL changes
- Experimental TanStack Router support with type-safe routing

React Context Selectors RFC update: Joe Savona from the React Compiler team shared an important update regarding fine-grained subscriptions in React to prevent re-renders.

They wonβt pursue the βuseContext in useMemoβ plan anymore and instead focus on React Compiler and Concurrent Stores with selectors (but this plan may change).- React Types PR - Fragment Refs: React fragments are set to become more powerful with this upcoming experimental feature, briefly mentioned in the latest React Labs post. The PR gives a sneak peek of the exposed Fragment Instance APIs. React Native should also expose dedicated APIs.
- React PR -
nameprop for<Suspense>and<Activity>: This upcoming experimental prop looks mostly useful in React DevTools to quickly identify built-in components and search for them. - Next.js PR -
export const prefetch: βstaticβ | βruntimeβ: This work-in-progress and unstable new API should let you control how path segments are prefetched. 
React docs - Custom Elements: New documentation teaching how to pass values and listen to events on custom HTML elements.
Remix v3 will explore a new JSX-based component model, not based on Preact anymore
