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
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
Goal: Achieve deterministic layout animations in Framer Motion (v10+) when components are conditionally rendered, ensuring repeatable behavior across renders in a development environment with hot module replacement (React 18). Uncertainty arises because the layout prop depends on synchronous DOM measurements that may be delayed by React 18's automatic batchi
Goal is to use Framer Motion layout animations and Presence mount and unmount handling in a React 18 application that server renders pages and hydrates on the client. The intent is to keep declarative animation props on motion components while relying on React 18 concurrent mode for rendering. Constraints involve the integration boundary between Framer Motio
Scenario I have a React 18 app (concurrent renderer) where a single user action applies a "schema change" to local UI state: several components update their shape at once, driven by multiple setState calls, and a companion async fetch validates the new schema. If that fetch rejects, I want the UI to return to the previous consistent state rather than showing
