It can be a value of any type, but there is a special behavior for functions. This argument is ignored after the initial render. + * If you pass a function as `initialState`, it will be treated as an _initializer function_. It should be pure, should take no arguments, and should return a value of any type. +``` + +**Callback parameter with sub-parameters:** +```md +* `subscribe`: A function that takes a single `callback` argument and subscribes it to the store. When the store changes, it should invoke the provided `callback`. The `subscribe` function should return a function that cleans up the subscription. +``` + +**Nested options object:** +```md +* **optional** `options`: An object with options for this React root. + * **optional** `onCaughtError`: Callback called when React catches an error in an Error Boundary. + * **optional** `onUncaughtError`: Callback called when an error is thrown and not caught. + * **optional** `identifierPrefix`: A string prefix React uses for IDs generated by `useId`. +``` + +--- + +### Return Value Patterns + +**Single value return:** +```md +`hookName` returns the current value. The value will be the same as `initialValue` during the first render. +``` + +**Array return (numbered list):** +```md +`useState` returns an array with exactly two values: + +1. The current state. During the first render, it will match the `initialState` you have passed. +2. The [`set` function](#setstate) that lets you update the state to a different value and trigger a re-render. +``` + +**Object return (bulleted list):** +```md +`createElement` returns a React element object with a few properties: + +* `type`: The `type` you have passed. +* `props`: The `props` you have passed except for `ref` and `key`. +* `ref`: The `ref` you have passed. If missing, `null`. +* `key`: The `key` you have passed, coerced to a string. If missing, `null`. +``` + +**Promise return:** +```md +`prerender` returns a Promise: +- If rendering is successful, the Promise will resolve to an object containing: + - `prelude`: a [Web Stream](MDN-link) of HTML. + - `postponed`: a JSON-serializable object for resumption. +- If rendering fails, the Promise will be rejected. +``` + +**Wrapped function return:** +```md +`cache` returns a cached version of `fn` with the same type signature. It does not call `fn` in the process. + +When calling `cachedFn` with given arguments, it first checks if a cached result exists. If cached, it returns the result. If not, it calls `fn`, stores the result, and returns it. +``` + +--- + +### Caveats Patterns + +**Standard Hook caveat (almost always first for Hooks):** +```md +* `useXxx` is a Hook, so you can only call it **at the top level of your component** or your own Hooks. You can't call it inside loops or conditions. If you need that, extract a new component and move the state into it. +``` + +**Stable identity caveat (for returned functions):** +```md +* The `set` function has a stable identity, so you will often see it omitted from Effect dependencies, but including it will not cause the Effect to fire. +``` + +**Strict Mode caveat:** +```md +* In Strict Mode, React will **call your render function twice** in order to help you find accidental impurities. This is development-only behavior and does not affect production. +``` + +**Caveat with code example:** +```md +* It's not recommended to _suspend_ a render based on a store value returned by `useSyncExternalStore`. For example, the following is discouraged: + + ```js + const selectedProductId = useSyncExternalStore(...); + const data = use(fetchItem(selectedProductId)) // X Don't suspend based on store value + ``` +``` + +**Canary caveat:** +```md +* If you want to pass `ref` to a Fragment, you can't use the `<>...` syntax. +``` + +--- + +### Troubleshooting Patterns + +**Heading format (first person problem statements):** +```md +### I've updated the state, but logging gives me the old value {/*old-value*/} + +### My initializer or updater function runs twice {/*runs-twice*/} + +### I want to read the latest state from a callback {/*read-latest-state*/} +``` + +**Error message format:** +```md +### I'm getting an error: "Too many re-renders" {/*too-many-rerenders*/} + +### I'm getting an error: "Rendered more hooks than during the previous render" {/*more-hooks*/} +``` + +**Lint error format:** +```md +### I'm getting a lint error: "[exact error message]" {/*lint-error-slug*/} +``` + +**Problem-solution structure:** +1.

Actions all The `action` function can operate synchronously or asynchronously. You can define them on the client side using standard JavaScript or on the server with the [`'use server'`](/reference/rsc/use-server) directive. When using an action, React will manage the life cycle of the data submission for you, providing hooks like [`useFormStatus`](/reference/react-dom/hooks/useFormStatus), and [`useActionState`](/reference/react/useActionState) to access the current state and response of the form action. -By default, Actions are submitted within a [transition](/reference/react/useTransition), keeping the current page interactive while the action is processing.

This allows you to show pending UI with the `isPending` state of a transition when an async request like `fetch` starts, and show the pending UI all the way through the update being applied. Alongside Actions, we're introducing a feature named [`useOptimistic`](/reference/react/useOptimistic) for managing optimistic state updates. With this hook, you can apply temporary updates that are automatically reverted once the final state commits. For Actions, this allows you to optimistically set the final state of the data on the client, assuming the submission is successful, and revert to the value for data received from the server. It works using regular `async`/`await`, so it works the same whether you're using `fetch` on the client, or a Server Action from the server. Library authors can implement custom `action={fn}` props in their own components with `useTransition`. Our intent is for libraries to adopt the Actions pattern when designing their component APIs, to provide a consistent experience for React developers. For example, if your library provides a `` component, consider also exposing a `` API, too. -While we initially focused on Server Actions for client-server data transfer, our philosophy for React is to provide the same programming model across all platforms and environments.

You can't call it inside loops or conditions. If you need that, extract a new component and move the state into it. +* React queues and executes multiple calls to `dispatchAction` sequentially. Each call to `reducerAction` receives the result of the previous call. +* The `dispatchAction` function has a stable identity, so you will often see it omitted from Effect dependencies, but including it will not cause the Effect to fire.

The reducer will perform side effects such as posting data, and return the new state. If `dispatchAction` is called multiple times, React queues and executes them in order so the result of the previous call is passed as `previousState` for the current call. + +#### Parameters {/*reduceraction-parameters*/} + +* `previousState`: The last state. Initially this is equal to the `initialState`. After the first call to `dispatchAction`, it's equal to the last state returned. + +* **optional** `actionPayload`: The argument passed to `dispatchAction`. It can be a value of any type. Similar to `useReducer` conventions, it is usually an object with a `type` property identifying it and, optionally, other properties with additional information. + +#### Returns {/*reduceraction-returns*/} + +`reducerAction` returns the new state, and triggers a Transition to re-render with that state. + +#### Caveats {/*reduceraction-caveats*/} + +* `reducerAction` can be sync or async. It can perform sync actions like showing a notification, or async actions like posting updates to a server. +* `reducerAction` is not invoked twice in `<StrictMode>` since `reducerAction` is designed to allow side effects. +* The return type of `reducerAction` must match the type of `initialState`. If TypeScript infers a mismatch, you may need to explicitly annotate your state type. +* If you set state after `await` in the `reducerAction` you currently need to wrap the state update in an additional `startTransition`.

The optimistic and real state converge in the same render when the Transition completes. + +<Note> + +#### Optimistic state is temporary {/*optimistic-state-is-temporary*/} + +Optimistic state only renders while an Action is in progress, otherwise `value` is rendered. + +If `saveChanges` returned `'c'`, then both `value` and `optimistic` will be `'c'`, not `'b'`. + +</Note> + +**How the final state is determined** + +The `value` argument to `useOptimistic` determines what displays after the Action finishes. How this works depends on the pattern you use: + +- **Hardcoded values** like `useOptimistic(false)`: After the Action, `state` is still `false`, so the UI shows `false`. This is useful for pending states where you always start from `false`. + +- **Props or state passed in** like `useOptimistic(isLiked)`: If the parent updates `isLiked` during the Action, the new value is used after the Action completes. This is how the UI reflects the result of the Action. + +- **Reducer pattern** like `useOptimistic(items, fn)`: If `items` changes while the Action is pending, React re-runs your `reducer` with the new `items` to recalculate the state. This keeps your optimistic additions on top of the latest data. + +**What happens when the Action fails** + +If the Action throws an error, the Transition still ends, and React renders with whatever `value` currently is. Since the parent typically only updates `value` on success, a failure means `value` hasn't changed, so the UI shows what it showed before the optimistic update. You can catch the error to show a message to the user. + +</DeepDive> --- ## Usage {/*usage*/} -### Optimistically updating forms {/*optimistically-updating-with-forms*/} +### Adding optimistic state to a component {/*adding-optimistic-state-to-a-component*/} + +Call `useOptimistic` at the top level of your component to declare one or more optimistic states. + +```js [[1, 4, "age"], [1, 5, "name"], [1, 6, "todos"], [2, 4, "optimisticAge"], [2, 5, "optimisticName"], [2, 6, "optimisticTodos"], [3, 4, "setOptimisticAge"], [3, 5, "setOptimisticName"], [3, 6, "setOptimisticTodos"], [4, 6, "reducer"]] +import { useOptimistic } from 'react'; + +function MyComponent({age, name, todos}) { + const [optimisticAge, setOptimisticAge] = useOptimistic(age); + const [optimisticName, setOptimisticName] = useOptimistic(name); + const [optimisticTodos, setOptimisticTodos] = useOptimistic(todos, reducer); + // ... +``` + +`useOptimistic` returns an array with exactly two items: + +1.

In the context of forms, this technique helps to make apps feel more responsive. When a user submits a form, instead of waiting for the server's response to reflect the changes, the interface is immediately updated with the expected outcome. +By convention, props called inside `startTransition` are named with "Action". -For example, when a user types a message into the form and hits the "Send" button, the `useOptimistic` Hook allows the message to immediately appear in the list with a "Sending..." label, even before the message is actually sent to a server. This "optimistic" approach gives the impression of speed and responsiveness. The form then attempts to truly send the message in the background. Once the server confirms the message has been received, the "Sending..." label is removed. +Since `submitAction` is named with "Action", you know it's already called inside `startTransition`. + +See [Exposing `action` prop from components](/reference/react/useTransition#exposing-action-props-from-components) for the Action prop pattern. + +</DeepDive> + +--- + +### Adding optimistic state to Action props {/*adding-optimistic-state-to-action-props*/} + +When creating an [Action prop](/reference/react/useTransition#exposing-action-props-from-components), you can add `useOptimistic` to show immediate feedback. + +Here's a button that shows "Submitting..." while the `action` is pending: <Sandpack> +```js src/App.js +import { useState, startTransition } from 'react'; +import Button from './Button'; +import { submitForm } from './actions.js'; + +export default function App() { + const [count, setCount] = useState(0); + return ( + <div> + <Button action={async () => { + await submitForm(); + startTransition(() => { + setCount(c => c + 1); + }); + }}>Increment</Button> + {count > 0 && <p>Submitted {count}!</p>} + </div> + ); +} +``` + +```js src/Button.js active +import { useOptimistic, startTransition } from 'react'; + +export default function Button({ action, children }) { + const [isPending, setIsPending] = useOptimistic(false); + + return ( + <button + disabled={isPending} + onClick={() => { + startTransition(async () => { + setIsPending(true); + await action(); + }); + }} + > + {isPending ?
