Develops React and Next.js App Router web applications, components and server rendering. Use when editing .jsx or .tsx components, hooks, Server Components or app/ routes, fixing a hydration mismatch, slow re-renders or bundle size, or adding a shadcn/ui component, including a small useEffect fix.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## Scope

React 19+ application engineering and Next.js App Router (15/16+): component
boundaries, composition and state, the performance rule set, App Router
semantics, Cache Components, and shadcn/ui usage.

Not covered — do not answer from this skill:

- Visual and UX design decisions (palette, type scale, spacing, motion,
  accessibility audits). Those belong to the `frontend-design` skill.
- Vue, Svelte, Solid, Astro islands. Use the `vue`, `svelte` or `astro` skill.
- The React Native and Expo runtime — Hermes, the New Architecture, FlashList,
  navigation, EAS. Use the `react-native` skill.
- Pages Router feature work. Only the v16 `middleware.ts` → `proxy.ts` rename
  is covered, because it breaks App Router projects too.
- Test-runner mechanics, CI, container and cloud configuration beyond the three
  self-hosting facts in `references/nextjs-ops-and-debug.md`.
- Server-side Node frameworks — Fastify, NestJS, Hono, and the process,
  logging, shutdown and streams concerns around them. Use the
  `nodejs-backend` skill.
- Component API details of shadcn/ui. Those are fetched at task time from the

How to install

The exact contents, by fingerprint

mdr add lynricsy/hyperskills/react@sha256:a96e7089afcce046

The line at the top of this page pins the label v2026.11.04, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
