This makes the allowed component return values consistent with values that are allowed in the middle of a component tree. We suggest to use a linter to prevent mistakes like forgetting a `return` statement before JSX. +* **In tests, `act` warnings are now opt-in:** If you're running end-to-end tests, the `act` warnings are unnecessary. We've introduced an [opt-in](https://github.com/reactwg/react-18/discussions/102) mechanism so you can enable them only for unit tests where they are useful and beneficial. +* **No warning about `setState` on unmounted components:** Previously, React warned about memory leaks when you call `setState` on an unmounted component. This warning was added for subscriptions, but people primarily run into it in scenarios where setting state is fine, and workarounds make the code worse. We've [removed](https://github.com/react/react/pull/22114) this warning. +* **No suppression of console logs:** When you use Strict Mode, React renders each component twice to help you find unexpected side effects. In React 17, we've suppressed console logs for one of the two renders to make the logs easier to read. In response to [community feedback](https://github.com/react/react/issues/21783) about this being confusing, we've removed the suppression. Instead, if you have React DevTools installed, the second log's renders will be displayed in grey, and there will be an option (off by default) to suppress them completely. +* **Improved memory usage:** React now cleans up more internal fields on unmount, making the impact from unfixed memory leaks that may exist in your application code less severe. +>>>>>>> 12d692da47e77cdc558b928fcfbaf4e71c6d0cec ### React DOM Server {/*react-dom-server*/} @@ -328,4 +340,8 @@ Internet Explorer のサポートが必要な場合は、React 17 を使い続 ## Changelog {/*changelog*/} +<<<<<<< HEAD [変更履歴の全リストはこちら](https://github.com/facebook/react/blob/main/CHANGELOG.md)を参照してください。 +======= +You can view the [full changelog here](https://github.com/react/react/blob/main/CHANGELOG.md). +>>>>>>> 12d692da47e77cdc558b928fcfbaf4e71c6d0cec diff --git a/src/content/blog/2022/03/29/react-v18.md b/src/content/blog/2022/03/29/react-v18.md index b93e2208e..69c169368 100644 --- a/src/content/blog/2022/03/29/react-v18.md +++ b/src/content/blog/2022/03/29/react-v18.md @@ -270,75 +270,75 @@ React 18 の strict モードでは、開発時にコンポーネントがマウ ### React {/*react*/} -* Add `useTransition` and `useDeferredValue` to separate urgent updates from transitions.

If your framework uses Server Components by default, add the [`'use client'`](/reference/rsc/use-client) directive to that file or move the call to a child Client Component: + +```js {1} +'use client'; + +import { use, useState } from 'react'; +import { browser } from 'react-dom'; + +export default function SavedDraft() { + use(browser('The saved draft is stored in localStorage.')); + const [draft] = useState(() => localStorage.getItem('draft') ?? ''); + return ; +} +``` + + + +--- + +### Conditionally rendering in the browser {/*conditionally-rendering-in-the-browser*/} + +Like other calls to [`use`](/reference/react/use), you can call `use(browser())` conditionally or inside a custom Hook. For example, you can wrap a Suspense-enabled data-fetching library's `useQuery` and skip server rendering when initial data is missing: + +```js {3} +function useBrowserQuery(query, options) { + if (options.initialData === undefined) { + use(browser('useBrowserQuery: No initial data was provided.')); + } + + return useQuery(query, options); +} + +function ProductDetails({ productId, initialData }) { + const product = useBrowserQuery(`/api/products/${productId}`, { + initialData, + }); + + return

{product.name}

; +} +``` + +On the server, `useBrowserQuery` calls `useQuery` only when `initialData` is available. Otherwise, the closest Suspense boundary's fallback remains in the HTML.

When React leaves a Suspense fallback for the browser, it does not call the server renderer's `onError` callback or [`hydrateRoot`'s `onRecoverableError`](/reference/react-dom/client/hydrateRoot#error-logging-in-production) callback. This example also passes a reason, which is available as the reported error's `cause`: + +```js +import { Suspense, use, useState } from 'react'; +import { browser } from 'react-dom'; +import { renderToPipeableStream } from 'react-dom/server'; + +function SavedDraft() { + use(browser(() => new Error('The saved draft is stored in localStorage.'))); + const [draft] = useState(() => localStorage.getItem('draft') ??

}> + + , + { + onShellReady() { + pipe(response); + }, + onBrowserBailout(error, errorInfo) { + logBrowserBailout(error, errorInfo); + } + } +); +``` + +`onBrowserBailout` receives two arguments: + +1. An `Error` describing the browser-only render. If you passed a reason to `browser`, it is available as the error's `cause`. +2. An `errorInfo` object with a `componentStack` showing where browser-only rendering occurred. + +The reason function can return any value. Return a new `Error` to give the cause its own stack without creating the `Error` in the browser. React does not serialize the reason into the HTML. + +If there is no Suspense boundary to provide a fallback, the server render fails. React reports the failure through the renderer's usual error callbacks instead of `onBrowserBailout`. + +--- + +### Aborting pending server rendering for the browser {/*aborting-pending-server-rendering-for-the-browser*/} + +If you call a server rendering API directly, you can stop waiting for pending content and let the browser finish rendering it. Pass the value returned by `browser` as the reason when aborting the server render. React then leaves pending Suspense boundaries in their fallback state and renders their content in the browser: + +```js {1,8} +import { browser } from 'react-dom'; +import { renderToPipeableStream } from 'react-dom/server'; + +const { pipe, abort } = renderToPipeableStream(, { + onShellReady() { + pipe(response); + setTimeout(() => { + abort(browser('The server render timed out.')); + }, 10000); + } +}); +``` + +A `browser` abort reason does not trigger the server renderer's `onError` callback or `hydrateRoot`'s `onRecoverableError` callback.
