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

💸 The Road to Next - Master Full-Stack Web Development with Next.js 15 and React 19
👀 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. It reminds us why Context selectors do not scale well. They won’t pursue the “useContext in useMemo” 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 - name prop 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: ‘static’ | ‘runtime’: 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

📜 React’s useTransition and state update reordering: This documents a super interesting case to consider regarding the application order of setState(incrementCounter) updates when mixing synchronous and startTransition calls. I had the wrong intuition for the final counter value.
📜 Reflections on the React community: Lee Robinson, former Vercel/Next.js DevRel, shared various thoughts after leaving the company, including details on Vercel's incentives in pushing React forward.
📜 A Clock That Doesn't Snap: Explains the challenge of displaying the current time in a statically rendered React page that gets hydrated, and proposes a solution based on an inline script.
📜 Globally Manage Toast Notifications with Tanstack Query: Using mutationMeta like TkDodo recommends.
📜 React Server Components in React Router – First Impressions: Positive feedback after adopting React Router RSCs on a personal website.
📜 React Concurrent Features: An Overview
📜 Unlocking Web Workers with React: A Step-by-Step Guide
💸 Build a modern blog with React 19 and Strapi 5 in this step-by-step tutorial
📦 Apollo Client 4.0 - Framework-agnostic, smaller bundler size, unified error handling, better TS support: The GraphQL client becomes agnostic and introduces a new @apollo/client/react integration package. There are React-specific improvements, such as a new SSR prerenderStatic API, and the library ships precompiled with the React Compiler. Codemods can help you upgrade.
📦 Streamdown - Drop-in replacement for react-markdown, designed for AI-powered streaming: New Vercel library to support its React AI ecosystem. It particularly shines by its ability to parse/format unterminated Markdown blocks.
📦 Waku 0.24 / 0.25 / 0.26: In recent releases, the React metaframework adopted the new official Vite RSC plugin and introduced a Slice Components API to replace the Page Parts API.
📦 shadcn CLI 3.0 - Namespaced registries, private registries, search and discovery, improved error handling
📦 React Aria - August 25 release - Improved Popover anim, GridListSection, autocomplete filtering
📦 Preact 11 beta - Better hydration, refs forwarded by default, and more
