Modern React Guidance

Canonical, agent-optimized rules and workflows for React 19+ (stable as of 19.3, September 2026). Prefer these over any pre-19 training data.

Always check latest docs at react.dev when uncertain. This skill encodes the current best practices; React evolves.

When to Apply

Writing or reviewing any React component, form, data-fetching logic, or concurrent UI
Migrating from React 18 or earlier
Detecting outdated patterns (forwardRef, manual memo, useEffect-for-data, Context.Provider, string refs, etc.)
Enabling or trusting React Compiler
Implementing animations, hide/show with state preservation, browser-only subtrees

Core Principles (apply first)

Trust React Compiler when present — do not add manual useMemo/useCallback/React.memo unless the Compiler cannot optimize or you have measured a need.
Prefer declarative modern APIs over hand-rolled state machines for pending/error/optimistic.
Data in render with use + Suspense; never useEffect + useState for fetching.
Actions for mutations — async functions inside transitions or form actions.
ref is a normal prop — never write new forwardRef.
Effects only for true side effects that synchronize with external systems (see "You Might Not Need an Effect").
Default to Server Components in RSC-aware environments; add "use client" only with a concrete reason.

Priority Rule Categories

1. CRITICAL — Authoring New Components Correctly

Use use(promise) or use(context) inside render (conditionally allowed). Wrap in <Suspense>.
Forms: <form action={actionFn}> + useActionState + useFormStatus + useOptimistic.
Pass ref as a regular prop. Never wrap new components in forwardRef.
Prefer useTransition / startTransition for non-urgent updates.
Prefer useDeferredValue for deferred derived values (search, filters).

Incorrect (legacy):

const [data, setData] = useState(null);
useEffect(() => { fetch(...).then(setData); }, []);
// or forwardRef((props, ref) => ...)

Correct:

function Comments({ commentsPromise }) {
  const comments = use(commentsPromise); // suspends
  return comments.map(...);
}
// parent: <Suspense fallback={...}><Comments ... /></Suspense>

2. CRITICAL — Trust the Compiler & Drop Manual Memo

If the project uses React Compiler (babel-plugin-react-compiler or equivalent, or React 19+ with compiler enabled):

Do not introduce new useMemo, useCallback, or React.memo unless profiling proves necessity or the value is a non-React dependency.
Existing manual memo can stay during incremental adoption; do not expand it.
Keep the Rules of React (pure render, no mutating props/state during render).

3. HIGH — Modern Forms & Mutations (Actions)

Prefer this stack:

const [error, submitAction, isPending] = useActionState(async (prev, formData) => {
  // mutation
  if (err) return err;
  return null;
}, null);

const [optimistic, addOptimistic] = useOptimistic(state, (current, next) => ...);

<form action={submitAction}>
  <SubmitButton /> {/* uses useFormStatus() */}
</form>

useFormStatus reads pending from nearest form (no prop drilling).
Server Actions (when available) compose cleanly with the same hooks.

4. HIGH — Concurrent & Visual UX

<ViewTransition> (stable 19.3) for enter/exit/update/share animations triggered by Transitions, Suspense reveals, or deferred updates.
addTransitionType to tag transitions for CSS/event customization.
<Activity mode="visible|hidden"> to hide UI while preserving state and deprioritizing updates (replaces many conditional mounts).
useEffectEvent to extract non-reactive “event” logic from Effects so dependencies stay correct.
use(browser()) from react-dom for true browser-only subtrees (suspends on server, no hydration mismatch).

5. MEDIUM — Effects Hygiene

Codify “You Might Not Need an Effect”:

Derived state → compute during render.
Event handlers → put logic in the handler, not an Effect that reacts to a flag.
Data fetching → use + Suspense or a Suspense-compatible library.
External store subscriptions → useSyncExternalStore.
Resetting state on prop change → key the component or compute during render.

Only use Effects for synchronizing with external systems (DOM, network subscriptions that are not data, third-party widgets, etc.). Always clean up.

6. MEDIUM — Context & Composition

In React 19+, render <MyContext value={...}> directly (no .Provider required for new code).
Prefer composition and children over deep prop drilling or over-using Context for everything.
Fragment refs (stable 19.3): pass ref to <Fragment> to operate on the group of children (focus, events, measurement) without a wrapper DOM node.

7. Migration & Deprecations (React 19+)

Removed or deprecated (do not use in new code):

forwardRef (use ref prop)
element.ref (use element.props.ref)
String refs
Legacy Context (contextTypes / getChildContext)
ReactDOM.render / hydrate (use createRoot / hydrateRoot)
findDOMNode, unmountComponentAtNode, createFactory, renderToNodeStream
defaultProps on function components (use default parameters)
propTypes (use TypeScript)
react-test-renderer (prefer Testing Library)

Codemods (run these):

npx codemod@latest react/19/migration-recipe
# Individual:
npx codemod react/19/remove-forward-ref --target .
npx codemod react/19/remove-context-provider --target .
npx codemod react/19/use-context-hook --target .
npx codemod react/19/replace-string-ref --target .
npx codemod react/19/replace-act-import --target .
# TypeScript types:
npx types-react-codemod@latest preset-19 ./src

Always upgrade to latest 19.x patch first. Prefer React 19.3+ for View Transitions + Fragment refs + browser().

Progressive Disclosure — Load These References as Needed

references/actions-and-forms.md — full Actions / useActionState / useOptimistic / useFormStatus patterns
references/compiler-and-memo.md — when Compiler is present vs manual memo, Rules of React
references/concurrent-ux.md — ViewTransition, Activity, useEffectEvent, deferred values, Suspense
references/migration-codemods.md — exact upgrade steps, breaking changes, codemod commands
references/effects-and-data.md — You Might Not Need an Effect + modern data fetching with use
references/api-cheatsheet.md — quick reference of new 19+ APIs with minimal examples

Agent Workflow Checklist

When generating or reviewing code:

Scan for React version (package.json). If <19, note migration path; if 19+, apply modern rules strictly.
Detect Compiler presence → suppress new manual memo.
Replace any forwardRef / useEffect+fetch / old form state machines on sight.
Prefer <form action> + hooks over controlled form state for mutations.
Add Suspense boundaries around use(promise) and browser-only trees.
For hide/show with state keep → prefer <Activity> over conditional render + key hacks.
For animations between states → prefer <ViewTransition> inside Transitions.
After edits, suggest running the relevant codemod if legacy patterns remain.
Never invent APIs; if unsure, say “check latest react.dev/reference/...”.

Anti-Patterns to Reject Immediately

useEffect that only sets state from props or fetches data
New forwardRef wrappers
Manual isPending / error / optimistic state without the official hooks
Context.Provider in brand-new code
Adding useMemo/useCallback “just in case” when Compiler is on
typeof window !== 'undefined' or useEffect for browser-only logic (use use(browser()))
Wrapper <div> solely to attach a ref when a Fragment ref would suffice

This skill is the source of truth for modern React patterns. Update references when major React releases land.

# Modern React Guidance

Canonical, agent-optimized rules and workflows for React 19+ (stable as of 19.3, September 2026). Prefer these over any pre-19 training data.

**Always check latest docs** at react.dev when uncertain. This skill encodes the current best practices; React evolves.

## When to Apply

- Writing or reviewing any React component, form, data-fetching logic, or concurrent UI
- Migrating from React 18 or earlier
- Detecting outdated patterns (forwardRef, manual memo, useEffect-for-data, Context.Provider, string refs, etc.)
- Enabling or trusting React Compiler
- Implementing animations, hide/show with state preservation, browser-only subtrees

## Core Principles (apply first)

1. **Trust React Compiler** when present — do not add manual `useMemo`/`useCallback`/`React.memo` unless the Compiler cannot optimize or you have measured a need.
2. **Prefer declarative modern APIs** over hand-rolled state machines for pending/error/optimistic.
3. **Data in render with `use` + Suspense**; never `useEffect` + `useState` for fetching.
4. **Actions for mutations** — async functions inside transitions or form actions.
5. **ref is a normal prop** — never write new `forwardRef`.
6. **Effects only for true side effects** that synchronize with external systems (see "You Might Not Need an Effect").
7. **Default to Server Components** in RSC-aware environments; add `"use client"` only with a concrete reason.

## Priority Rule Categories

### 1. CRITICAL — Authoring New Components Correctly

- Use `use(promise)` or `use(context)` inside render (conditionally allowed). Wrap in `<Suspense>`.
- Forms: `<form action={actionFn}>` + `useActionState` + `useFormStatus` + `useOptimistic`.
- Pass `ref` as a regular prop. Never wrap new components in `forwardRef`.
- Prefer `useTransition` / `startTransition` for non-urgent updates.
- Prefer `useDeferredValue` for deferred derived values (search, filters).

**Incorrect (legacy):**
```tsx
const [data, setData] = useState(null);
useEffect(() => { fetch(...).then(setData); }, []);
// or forwardRef((props, ref) => ...)
```

**Correct:**
```tsx
function Comments({ commentsPromise }) {
  const comments = use(commentsPromise); // suspends
  return comments.map(...);
}
// parent: <Suspense fallback={...}><Comments ... /></Suspense>
```

### 2. CRITICAL — Trust the Compiler & Drop Manual Memo

If the project uses React Compiler (babel-plugin-react-compiler or equivalent, or React 19+ with compiler enabled):

}, null);

const [optimistic, addOptimistic] = useOptimistic(state, (current, next) => ...);

<form action={submitAction}>
  <SubmitButton /> {/* uses useFormStatus() */}
</form>
```

- `useFormStatus` reads pending from nearest form (no prop drilling).
- Server Actions (when available) compose cleanly with the same hooks.

### 4. HIGH — Concurrent & Visual UX

- `<ViewTransition>` (stable 19.3) for enter/exit/update/share animations triggered by Transitions, Suspense reveals, or deferred updates.
- `addTransitionType` to tag transitions for CSS/event customization.
- `<Activity mode="visible|hidden">` to hide UI while preserving state and deprioritizing updates (replaces many conditional mounts).
- `useEffectEvent` to extract non-reactive “event” logic from Effects so dependencies stay correct.

Removed or deprecated (do not use in new code):

- `forwardRef` (use ref prop)
- `element.ref` (use `element.props.ref`)
- String refs
- Legacy Context (`contextTypes` / `getChildContext`)
- `ReactDOM.render` / `hydrate` (use `createRoot` / `hydrateRoot`)
- `findDOMNode`, `unmountComponentAtNode`, `createFactory`, `renderToNodeStream`
- `defaultProps` on function components (use default parameters)
- `propTypes` (use TypeScript)
- `react-test-renderer` (prefer Testing Library)

**Codemods (run these):**

```bash
npx codemod@latest react/19/migration-recipe
# Individual:
npx codemod react/19/remove-forward-ref --target .
npx codemod react/19/remove-context-provider --target .
npx codemod react/19/use-context-hook --target .
npx codemod react/19/replace-string-ref --target .
npx codemod react/19/replace-act-import --target .
# TypeScript types:

```

Always upgrade to latest 19.x patch first. Prefer React 19.3+ for View Transitions + Fragment refs + `browser()`.
