React 18 lets you mark state updates as interruptible instead of debouncing them. This post explains when to use useTransition versus useDeferredValue, with a DevTools workflow to verify the split on a throttled CPU profile.
Use React 18's useId hook to generate stable, hydration-safe IDs for labels and form controls without Math.random() or counters.
Learn how React 18's automatic batching and the useTransition hook can keep your UI smooth when filtering thousands of items, with a concrete code example and trade‑offs to consider.
React 18 automatically batches state updates from timers, promises, and native events into one render when using createRoot. Learn the mechanism, limits, and how to verify it with the Profiler.
React 18's automatic batching merges state updates from timeouts, promises, and handlers into one render — but only with createRoot. Here's how to enable it, verify it with the Profiler, and handle the exceptions.
Framer Motion's layout prop automates FLIP animations for position and size changes. This post explains how it works, shows a reorderable list example, and covers performance traps in React 18 concurrent mode.
Integrating Mapbox GL JS v2+ within a React 18 environment introduces a conflict between React's declarative state management and Mapbox's imperative API. While wrappers like react-map-gl provide a useMap hook, maintaining a single source of truth for the viewport (center, zoom, and bearing) becomes complex when using external state managers such as Redux or
Automatic Batching Divergence In React 17 development, state updates inside event handlers are automatically batched while updates in asynchronous callbacks remain unbatched. React 18 production enables automatic batching for all updates inside event handlers, which can combine multiple setState calls into a single render and affect side‑effect ordering. Sho
Integration boundary Remix v2 loaders execute on the server and pass data to route components via useLoaderData , while React 18's concurrent renderer introduces use() for reading promises inside components and reorders work across suspense boundaries. The two systems have different assumptions about when data becomes available and how component trees suspen
