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/react/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 [`useFormState`](/reference/react-dom/hooks/useFormState) 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. Since Actions support async functions, we've also added the ability to use `async/await` in transitions. 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. +By default, Actions are submitted within a [transition](/reference/react/useTransition), keeping the current page interactive while the action is processing. Since Actions support async functions, we've also added the ability to use `async/await` in transitions. 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. @@ -76,7 +76,7 @@ React Server Components, Asset Loading, Document Metadata, and Actions have all - **Document Metadata**: we added built-in support for rendering [``](/reference/react-dom/components/title), [`<meta>`](/reference/react-dom/components/meta), and metadata [`<link>`](/reference/react-dom/components/link) tags anywhere in your component tree. These work the same way in all environments, including fully client-side code, SSR, and RSC. This provides built-in support for features pioneered by libraries like [React Helmet](https://github.com/nfl/react-helmet). -- **Asset Loading**: we integrated Suspense with the loading lifecycle of resources such as stylesheets, fonts, and scripts so that React takes them into account to determine whether the content in elements like [`<style>`](/reference/react-dom/components/style), [`<link>`](/reference/react-dom/components/link), and [`<script>`](/reference/react-dom/components/script) are ready to be displayed. We’ve also added new [Resource Loading APIs](/reference/react-dom#resource-preloading-apis) like `preload` and `preinit` give greater control for when a resource should load and initialize. +- **Asset Loading**: we integrated Suspense with the loading lifecycle of resources such as stylesheets, fonts, and scripts so that React takes them into account to determine whether the content in elements like [`<style>`](/reference/react-dom/components/style), [`<link>`](/reference/react-dom/components/link), and [`<script>`](/reference/react-dom/components/script) are ready to be displayed.
