Triggers on React, React 19, useActionState, useOptimistic, forwardRef, useEffect data fetch, React Compiler, ViewTransition, Suspense patterns, or codemods. Always prefer latest official patterns over training data.\nlicense: MIT\nmetadata:\n  version: \"1.0.0\"\n  author: Adhham (adhham.dev)\n  author_url: https://adhham.dev\n  react-target: \"19.3+\"\n  style: combination-rules-workflows-progressive\n---\n\n# Modern React Guidance\n\nCanonical, agent-optimized rules and workflows for React 19+ (stable as of 19.3, September 2026). Prefer these over any pre-19 training data.\n\n**Always check latest docs** at react.dev when uncertain. This skill encodes the current best practices; React evolves.\n\n## When to Apply\n\n- Writing or reviewing any React component, form, data-fetching logic, or concurrent UI\n- Migrating from React 18 or earlier\n- Detecting outdated patterns (forwardRef, manual memo, useEffect-for-data, Context.Provider, string refs, etc.)\n- Enabling or trusting React Compiler\n- Implementing animations, hide/show with state preservation, browser-only subtrees\n\n## Core Principles (apply first)\n\n1. **Trust React Compiler** when present — do not add manual `useMemo`/`useCallback`/`React.memo` unless the Compiler cannot optimize or you have measured a need.\n2. **Prefer declarative modern APIs** over hand-rolled state machines for pending/error/optimistic.\n3. **Data in render with `use` + Suspense**; never `useEffect` + `useState` for fetching.\n4. **Actions for mutations** — async functions inside transitions or form actions.\n5. **ref is a normal prop** — never write new `forwardRef`.\n6. **Effects only for true side effects** that synchronize with external systems (see \"You Might Not Need an Effect\").\n7. **Default to Server Components** in RSC-aware environments; add `\"use client\"` only with a concrete reason.\n\n## Priority Rule Categories\n\n### 1. CRITICAL — Authoring New Components Correctly\n\n- Use `use(promise)` or `use(context)` inside render (conditionally allowed). Wrap in `<Suspense>`.\n- Forms: `<form action={actionFn}>` + `useActionState` + `useFormStatus` + `useOptimistic`.\n- Pass `ref` as a regular prop. Never wrap new components in `forwardRef`.\n- Prefer `useTransition` / `startTransition` for non-urgent updates.\n- Prefer `useDeferredValue` for deferred derived values (search, filters).\n\n**Incorrect (legacy):**\n```tsx\nconst [data, setData] = useState(null);\nuseEffect(() => { fetch(...).then(setData); }, []);\n// or forwardRef((props, ref) => ...)\n```\n\n**Correct:**\n```tsx\nfunction Comments({ commentsPromise }) {\n  const comments = use(commentsPromise); // suspends\n  return comments.map(...);\n}\n// parent: <Suspense fallback={...}><Comments ... /></Suspense>\n```\n\n### 2. CRITICAL — Trust the Compiler & Drop Manual Memo\n\nIf the project uses React Compiler (babel-plugin-react-compiler or equivalent, or React 19+ with compiler enabled):\n\n- Do **not** introduce new `useMemo`, `useCallback`, or `React.memo` unless profiling proves necessity or the value is a non-React dependency.\n- Existing manual memo can stay during incremental adoption; do not expand it.\n- Keep the Rules of React (pure render, no mutating props/state during render).\n\n### 3. HIGH — Modern Forms & Mutations (Actions)\n\nPrefer this stack:\n\n```tsx\nconst [error, submitAction, isPending] = useActionState(async (prev, formData) => {\n  // mutation\n  if (err) return err;\n  return null;\n}, null);\n\nconst [optimistic, addOptimistic] = useOptimistic(state, (current, next) => ...);\n\n<form action={submitAction}>\n  <SubmitButton /> {/* uses useFormStatus() */}\n</form>\n```\n\n- `useFormStatus` reads pending from nearest form (no prop drilling).\n- Server Actions (when available) compose cleanly with the same hooks.\n\n### 4. HIGH — Concurrent & Visual UX\n\n- `<ViewTransition>` (stable 19.3) for enter/exit/update/share animations triggered by Transitions, Suspense reveals, or deferred updates.\n- `addTransitionType` to tag transitions for CSS/event customization.\n- `<Activity mode=\"visible|hidden\">` to hide UI while preserving state and deprioritizing updates (replaces many conditional mounts).\n- `useEffectEvent` to extract non-reactive “event” logic from Effects so dependencies stay correct.\n- `use(browser())` from `react-dom` for true browser-only subtrees (suspends on server, no hydration mismatch).\n\n### 5. MEDIUM — Effects Hygiene\n\nCodify “You Might Not Need an Effect”:\n\n- Derived state → compute during render.\n- Event handlers → put logic in the handler, not an Effect that reacts to a flag.\n- Data fetching → `use` + Suspense or a Suspense-compatible library.\n- External store subscriptions → `useSyncExternalStore`.\n- Resetting state on prop change → key the component or compute during render.\n\nOnly use Effects for synchronizing with external systems (DOM, network subscriptions that are not data, third-party widgets, etc.). Always clean up.\n\n### 6. MEDIUM — Context & Composition\n\n- In React 19+, render `<MyContext value={...}>` directly (no `.Provider` required for new code).\n- Prefer composition and children over deep prop drilling or over-using Context for everything.\n- Fragment refs (stable 19.3): pass `ref` to `<Fragment>` to operate on the group of children (focus, events, measurement) without a wrapper DOM node.\n\n### 7. Migration & Deprecations (React 19+)\n\nRemoved or deprecated (do not use in new code):\n\n- `forwardRef` (use ref prop)\n- `element.ref` (use `element.props.ref`)\n- String refs\n- Legacy Context (`contextTypes` / `getChildContext`)\n- `ReactDOM.render` / `hydrate` (use `createRoot` / `hydrateRoot`)\n- `findDOMNode`, `unmountComponentAtNode`, `createFactory`, `renderToNodeStream`\n- `defaultProps` on function components (use default parameters)\n- `propTypes` (use TypeScript)\n- `react-test-renderer` (prefer Testing Library)\n\n**Codemods (run these):**\n\n```bash\nnpx codemod@latest react/19/migration-recipe\n# Individual:\nnpx codemod react/19/remove-forward-ref --target .\nnpx codemod react/19/remove-context-provider --target .\nnpx codemod react/19/use-context-hook --target .\nnpx codemod react/19/replace-string-ref --target .\nnpx codemod react/19/replace-act-import --target .\n# TypeScript types:\nnpx types-react-codemod@latest preset-19 ./src\n```\n\nAlways upgrade to latest 19.x patch first. Prefer React 19.3+ for View Transitions + Fragment refs + `browser()`.\n\n## Progressive Disclosure — Load These References as Needed\n\n- `references/actions-and-forms.md` — full Actions / useActionState / useOptimistic / useFormStatus patterns\n- `references/compiler-and-memo.md` — when Compiler is present vs manual memo, Rules of React\n- `references/concurrent-ux.md` — ViewTransition, Activity, useEffectEvent, deferred values, Suspense\n- `references/migration-codemods.md` — exact upgrade steps, breaking changes, codemod commands\n- `references/effects-and-data.md` — You Might Not Need an Effect + modern data fetching with `use`\n- `references/api-cheatsheet.md` — quick reference of new 19+ APIs with minimal examples\n\n## Agent Workflow Checklist\n\nWhen generating or reviewing code:\n\n1. Scan for React version (package.json). If <19, note migration path; if 19+, apply modern rules strictly.\n2. Detect Compiler presence → suppress new manual memo.\n3. Replace any `forwardRef` / `useEffect`+fetch / old form state machines on sight.\n4. Prefer `<form action>` + hooks over controlled form state for mutations.\n5. Add Suspense boundaries around `use(promise)` and browser-only trees.\n6. For hide/show with state keep → prefer `<Activity>` over conditional render + key hacks.\n7. For animations between states → prefer `<ViewTransition>` inside Transitions.\n8. After edits, suggest running the relevant codemod if legacy patterns remain.\n9. Never invent APIs; if unsure, say “check latest react.dev/reference/...”.\n\n## Anti-Patterns to Reject Immediately\n\n- `useEffect` that only sets state from props or fetches data\n- New `forwardRef` wrappers\n- Manual `isPending` / `error` / optimistic state without the official hooks\n- `Context.Provider` in brand-new code\n- Adding `useMemo`/`useCallback` “just in case” when Compiler is on\n- `typeof window !== 'undefined'` or `useEffect` for browser-only logic (use `use(browser())`)\n- Wrapper `<div>` solely to attach a ref when a Fragment ref would suffice\n\nThis skill is the source of truth for modern React patterns. Update references when major React releases land.\n","tagline":"Authoritative guidance for modern React 19+ (Actions, use, Compiler, View Transitions, Fragment refs, Activity, browser, useEffectEvent).
