}
```
We're also including a codemod for the most common replacements. See [TypeScript changes](#typescript-changes) below.
+## Codemods {/*codemods*/}
+
+To help with the upgrade, we've worked with the team at [codemod.com](https://codemod.com) to publish codemods that will automatically update your code to many of the new APIs and patterns in React 19.
+
+All codemods are available in the [`react-codemod` repo](https://github.com/reactjs/react-codemod) and the Codemod team have joined in helping maintain the codemods. To run these codemods, we recommend using the `codemod` command instead of the `react-codemod` because it runs faster, handles more complex code migrations, and provides better support for TypeScript.
+
+
+
+
+#### Run all React 19 codemods {/*run-all-react-19-codemods*/}
+
+Run all codemods listed in this guide with the React 19 `codemod` recipe:
+
+```bash
+npx codemod@latest react/19/migration-recipe
+```
+
+This will run the following codemods from `react-codemod`:
+- [`replace-reactdom-render`](https://github.com/reactjs/react-codemod?tab=readme-ov-file#replace-reactdom-render)
+- [`replace-string-ref`](https://github.com/reactjs/react-codemod?tab=readme-ov-file#replace-string-ref)

+title: "React Compiler Beta Release"
+author: Lauren Tan
+date: 2024/10/21
+description: At React Conf 2024, we announced the experimental release of React Compiler, a build-time tool that optimizes your React app through automatic memoization. In this post, we want to share what's next for open source, and our progress on the compiler.
+
+---
+
+October 21, 2024 by [Lauren Tan](https://twitter.com/potetotes).
+
+---
+
+
+
+The React team is excited to share new updates:
+
+
+
+1. We're publishing React Compiler Beta today, so that early adopters and library maintainers can try it and provide feedback.
+2. We're officially supporting React Compiler for apps on React 17+, through an optional `react-compiler-runtime` package.
+3. We're opening up public membership of the [React Compiler Working Group](https://github.com/reactwg/react-compiler) to prepare the community for gradual adoption of the compiler.
+
+---
+
+At [React Conf 2024](/blog/2024/05/22/react-conf-2024-recap), we announced the experimental release of React Compiler, a build-time tool that optimizes your React app through automatic memoization. [You can find an introduction to React Compiler here](/learn/react-compiler).
+
+Since the first release, we've fixed numerous bugs reported by the React community, received several high quality bug fixes and contributions[^1] to the compiler, made the compiler more resilient to the broad diversity of JavaScript patterns, and have continued to roll out the compiler more widely at Meta.
+
+In this post, we want to share what's next for React Compiler.
+
+## Try React Compiler Beta today {/*try-react-compiler-beta-today*/}
+
+At [React India 2024](https://www.youtube.com/watch?v=qd5yk2gxbtg), we shared an update on React Compiler. Today, we are excited to announce a new Beta release of React Compiler and ESLint plugin. New betas are published to npm using the `@beta` tag.
+
+To install React Compiler Beta:
+
+
+npm install -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta
+
+
+Or, if you're using Yarn:
+
+
+yarn add -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta
+
+
+You can watch [Sathya Gunasekaran's](https://twitter.com/_gsathya) talk at React India here:
+
+
+
+## We recommend everyone use the React Compiler linter today {/*we-recommend-everyone-use-the-react-compiler-linter-today*/}
+
+React Compiler’s ESLint plugin helps developers proactively identify and correct [Rules of React](/reference/rules) violations. **We strongly recommend everyone use the linter today**. The linter does not require that you have the compiler installed, so you can use it independently, even if you are not ready to try out the compiler.
+
+To install the linter only:
+
+
+npm install -D eslint-plugin-react-compiler@beta
+
+
+Or, if you're using Yarn:
+
+
+yarn add -D eslint-plugin-react-compiler@beta
+
+
+After installation you can enable the linter by [adding it to your ESLint config](/learn/react-compiler#installing-eslint-plugin-react-compiler). Using the linter helps identify Rules of React breakages, making it easier to adopt the compiler when it's fully released.
+
+## Backwards Compatibility {/*backwards-compatibility*/}
+
+React Compiler produces code that depends on runtime APIs added in React 19, but we've since added support for the compiler to also work with React 17 and 18. If you are not on React 19 yet, in the Beta release you can now try out React Compiler by specifying a minimum `target` in your compiler config, and adding `react-compiler-runtime` as a dependency. [You can find docs on this here](/learn/react-compiler#using-react-compiler-with-react-17-or-18).
+
+## Using React Compiler in libraries {/*using-react-compiler-in-libraries*/}
+
+Our initial release was focused on identifying major issues with using the compiler in applications. We've gotten great feedback and have substantially improved the compiler since then. We're now ready for broad feedback from the community, and for library authors to try out the compiler to improve performance and the developer experience of maintaining your library.
+
+React Compiler can also be used to compile libraries. Because React Compiler needs to run on the original source code prior to any code transformations, it is not possible for an application's build pipeline to compile the libraries they use. Hence, our recommendation is for library maintainers to independently compile and test their libraries with the compiler, and ship compiled code to npm.
+
+Because your code is pre-compiled, users of your library will not need to have the compiler enabled in order to benefit from the automatic memoization applied to your library. If your library targets apps not yet on React 19, specify a minimum `target` and add `react-compiler-runtime` as a direct dependency. The runtime package will use the correct implementation of APIs depending on the application's version, and polyfill the missing APIs if necessary.
+
+[You can find more docs on this here.](/learn/react-compiler#using-the-compiler-on-libraries)
+
+## Opening up React Compiler Working Group to everyone {/*opening-up-react-compiler-working-group-to-everyone*/}
+
+We previously announced the invite-only [React Compiler Working Group](https://github.com/reactwg/react-compiler) at React Conf to provide feedback, ask questions, and collaborate on the compiler's experimental release.
+
+From today, together with the Beta release of React Compiler, we are opening up Working Group membership to everyone. The goal of the React Compiler Working Group is to prepare the ecosystem for a smooth, gradual adoption of React Compiler by existing applications and libraries. Please continue to file bug reports in the [React repo](https://github.com/facebook/react), but please leave feedback, ask questions, or share ideas in the [Working Group discussion forum](https://github.com/reactwg/react-compiler/discussions).
+
+The core team will also use the discussions repo to share our research findings. As the Stable Release gets closer, any important information will also be posted on this forum.
+
+## React Compiler at Meta {/*react-compiler-at-meta*/}
+
+At [React Conf](/blog/2024/05/22/react-conf-2024-recap), we shared that our rollout of the compiler on Quest Store and Instagram were successful. Since then, we've deployed React Compiler across several more major web apps at Meta, including [Facebook](https://www.facebook.com) and [Threads](https://www.threads.net). That means if you've used any of these apps recently, you may have had your experience powered by the compiler. We were able to onboard these apps onto the compiler with few code changes required, in a monorepo with more than 100,000 React components.
+
+We've seen notable performance improvements across all of these apps. As we've rolled out, we're continuing to see results on the order of [the wins we shared previously at ReactConf](https://youtu.be/lyEKhv8-3n0?t=3223). These apps have already been heavily hand tuned and optimized by Meta engineers and React experts over the years, so even improvements on the order of a few percent are a huge win for us.
+
+We also expected developer productivity wins from React Compiler. To measure this, we collaborated with our data science partners at Meta[^2] to conduct a thorough statistical analysis of the impact of manual memoization on productivity. Before rolling out the compiler at Meta, we discovered that only about 8% of React pull requests used manual memoization and that these pull requests took 31-46% longer to author[^3]. This confirmed our intuition that manual memoization introduces cognitive overhead, and we anticipate that React Compiler will lead to more efficient code authoring and review. Notably, React Compiler also ensures that *all* code is memoized by default, not just the (in our case) 8% where developers explicitly apply memoization.
+
+## Roadmap to Stable {/*roadmap-to-stable*/}
+
+*This is not a final roadmap, and is subject to change.*
+
+We intend to ship a Release Candidate of the compiler in the near future following the Beta release, when the majority of apps and libraries that follow the Rules of React have been proven to work well with the compiler. After a period of final feedback from the community, we plan on a Stable Release for the compiler. The Stable Release will mark the beginning of a new foundation for React, and all apps and libraries will be strongly recommended to use the compiler and ESLint plugin.
+
+* ✅ Experimental: Released at React Conf 2024, primarily for feedback from early adopters.
+* ✅ Public Beta: Available today, for feedback from the wider community.
+* 🚧 Release Candidate (RC): React Compiler works for the majority of rule-following apps and libraries without issue.
+* 🚧 General Availability: After final feedback period from the community.
+
+These releases also include the compiler's ESLint plugin, which surfaces diagnostics statically analyzed by the compiler. We plan to combine the existing eslint-plugin-react-hooks plugin with the compiler's ESLint plugin, so only one plugin needs to be installed.
+
+Post-Stable, we plan to add more compiler optimizations and improvements. This includes both continual improvements to automatic memoization, and new optimizations altogether, with minimal to no change of product code. Upgrading to each new release of the compiler is aimed to be straightforward, and each upgrade will continue to improve performance and add better handling of diverse JavaScript and React patterns.
+
+Throughout this process, we also plan to prototype an IDE extension for React. It is still very early in research, so we expect to be able to share more of our findings with you in a future React Labs blog post.

+title: React Compiler
+---
+
+
+This page will give you an introduction to React Compiler and how to try it out successfully.
+
+
+
+These docs are still a work in progress. More documentation is available in the [React Compiler Working Group repo](https://github.com/reactwg/react-compiler/discussions), and will be upstreamed into these docs when they are more stable.
+

+
+
+* Getting started with the compiler
+* Installing the compiler and ESLint plugin
+* Troubleshooting
+
+
+
+
+React Compiler is a new compiler currently in Beta, that we've open sourced to get early feedback from the community. While it has been used in production at companies like Meta, rolling out the compiler to production for your app will depend on the health of your codebase and how well you’ve followed the [Rules of React](/reference/rules).
+
+The latest Beta release can be found with the `@beta` tag, and daily experimental releases with `@experimental`.

It is a build-time only tool that automatically optimizes your React app. It works with plain JavaScript, and understands the [Rules of React](/reference/rules), so you don't need to rewrite any code to use it.
+
+The compiler also includes an [ESLint plugin](#installing-eslint-plugin-react-compiler) that surfaces the analysis from the compiler right in your editor. **We strongly recommend everyone use the linter today.** The linter does not require that you have the compiler installed, so you can use it even if you are not ready to try out the compiler.
+
+The compiler is currently released as `beta`, and is available to try out on React 17+ apps and libraries. To install the Beta:
+
+
+npm install -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta
+
+
+Or, if you're using Yarn:
+
+
+yarn add -D babel-plugin-react-compiler@beta eslint-plugin-react-compiler@beta
+
+
+If you are not using React 19 yet, please see [the section below](#using-react-compiler-with-react-17-or-18) for further instructions.
+
+### What does the compiler do? {/*what-does-the-compiler-do*/}
+
+In order to optimize applications, React Compiler automatically memoizes your code. You may be familiar today with memoization through APIs such as `useMemo`, `useCallback`, and `React.memo`. With these APIs you can tell React that certain parts of your application don't need to recompute if their inputs haven't changed, reducing work on updates. While powerful, it's easy to forget to apply memoization or apply them incorrectly. This can lead to inefficient updates as React has to check parts of your UI that don't have any _meaningful_ changes.
+
+The compiler uses its knowledge of JavaScript and React's rules to automatically memoize values or groups of values within your components and hooks. If it detects breakages of the rules, it will automatically skip over just those components or hooks, and continue safely compiling other code.
+
+
+React Compiler can statically detect when Rules of React are broken, and safely opt-out of optimizing just the affected components or hooks. It is not necessary for the compiler to optimize 100% of your codebase.
+
+
+If your codebase is already very well-memoized, you might not expect to see major performance improvements with the compiler. However, in practice memoizing the correct dependencies that cause performance issues is tricky to get right by hand.
+
+
+#### What kind of memoization does React Compiler add? {/*what-kind-of-memoization-does-react-compiler-add*/}
+
+The initial release of React Compiler is primarily focused on **improving update performance** (re-rendering existing components), so it focuses on these two use cases:
+
+1. **Skipping cascading re-rendering of components**
+ * Re-rendering `` causes many components in its component tree to re-render, even though only `` has changed
+1. **Skipping expensive calculations from outside of React**
+ * For example, calling `expensivelyProcessAReallyLargeArrayOfObjects()` inside of your component or hook that needs that data
+
+#### Optimizing Re-renders {/*optimizing-re-renders*/}
+
+React lets you express your UI as a function of their current state (more concretely: their props, state, and context). In its current implementation, when a component's state changes, React will re-render that component _and all of its children_ — unless you have applied some form of manual memoization with `useMemo()`, `useCallback()`, or `React.memo()`. For example, in the following example, `` will re-render whenever ``'s state changes:
+
+```javascript
+function FriendList({ friends }) {
+ const onlineCount = useFriendOnlineCount();
+ if (friends.length === 0) {
+ return ;
+ }
+ return (
+
+ {onlineCount} online
+ {friends.map((friend) => (
+
+ ))}
+
+
+ );
+}
+```
+[_See this example in the React Compiler Playground_](https://playground.react.dev/#N4Igzg9grgTgxgUxALhAMygOzgFwJYSYAEAYjHgpgCYAyeYOAFMEWuZVWEQL4CURwADrEicQgyKEANnkwIAwtEw4iAXiJQwCMhWoB5TDLmKsTXgG5hRInjRFGbXZwB0UygHMcACzWr1ABn4hEWsYBBxYYgAeADkIHQ4uAHoAPksRbisiMIiYYkYs6yiqPAA3FMLrIiiwAAcAQ0wU4GlZBSUcbklDNqikusaKkKrgR0TnAFt62sYHdmp+VRT7SqrqhOo6Bnl6mCoiAGsEAE9VUfmqZzwqLrHqM7ubolTVol5eTOGigFkEMDB6u4EAAhKA4HCEZ5DNZ9ErlLIWYTcEDcIA)
+
+React Compiler automatically applies the equivalent of manual memoization, ensuring that only the relevant parts of an app re-render as state changes, which is sometimes referred to as "fine-grained reactivity". In the above example, React Compiler determines that the return value of `` can be reused even as `friends` changes, and can avoid recreating this JSX _and_ avoid re-rendering `` as the count changes.
+
+#### Expensive calculations also get memoized {/*expensive-calculations-also-get-memoized*/}
+
+The compiler can also automatically memoize for expensive calculations used during rendering:
+
+```js
+// **Not** memoized by React Compiler, since this is not a component or hook
+function expensivelyProcessAReallyLargeArrayOfObjects() { /* ... */ }
+
+// Memoized by React Compiler since this is a component
+function TableContainer({ items }) {
+ // This function call would be memoized:
+ const data = expensivelyProcessAReallyLargeArrayOfObjects(items);
+ // ...
+}
+```
+[_See this example in the React Compiler Playground_](https://playground.react.dev/#N4Igzg9grgTgxgUxALhAejQAgFTYHIQAuumAtgqRAJYBeCAJpgEYCemASggIZyGYDCEUgAcqAGwQwANJjBUAdokyEAFlTCZ1meUUxdMcIcIjyE8vhBiYVECAGsAOvIBmURYSonMCAB7CzcgBuCGIsAAowEIhgYACCnFxioQAyXDAA5gixMDBcLADyzvlMAFYIvGAAFACUmMCYaNiYAHStOFgAvk5OGJgAshTUdIysHNy8AkbikrIKSqpaWvqGIiZmhE6u7p7ymAAqXEwSguZcCpKV9VSEFBodtcBOmAYmYHz0XIT6ALzefgFUYKhCJRBAxeLcJIsVIZLI5PKFYplCqVa63aoAbm6u0wMAQhFguwAPPRAQA+YAfL4dIloUmBMlODogDpAA)
+
+However, if `expensivelyProcessAReallyLargeArrayOfObjects` is truly an expensive function, you may want to consider implementing its own memoization outside of React, because:
+
+- React Compiler only memoizes React components and hooks, not every function
+- React Compiler's memoization is not shared across multiple components or hooks
+
+So if `expensivelyProcessAReallyLargeArrayOfObjects` was used in many different components, even if the same exact items were passed down, that expensive calculation would be run repeatedly. We recommend [profiling](https://react.dev/reference/react/useMemo#how-to-tell-if-a-calculation-is-expensive) first to see if it really is that expensive before making code more complicated.
+
+
+### Should I try out the compiler? {/*should-i-try-out-the-compiler*/}
+
+Please note that the compiler is still in Beta and has many rough edges. While it has been used in production at companies like Meta, rolling out the compiler to production for your app will depend on the health of your codebase and how well you've followed the [Rules of React](/reference/rules).
+
+**You don't have to rush into using the compiler now. It's okay to wait until it reaches a stable release before adopting it.** However, we do appreciate trying it out in small experiments in your apps so that you can [provide feedback](#reporting-issues) to us to help make the compiler better.
+
+## Getting Started {/*getting-started*/}
+
+In addition to these docs, we recommend checking the [React Compiler Working Group](https://github.com/reactwg/react-compiler) for additional information and discussion about the compiler.
+
+### Installing eslint-plugin-react-compiler {/*installing-eslint-plugin-react-compiler*/}
+
+React Compiler also powers an ESLint plugin. The ESLint plugin can be used **independently** of the compiler, meaning you can use the ESLint plugin even if you don't use the compiler.
+
+
+npm install -D eslint-plugin-react-compiler@beta
+
+
+Then, add it to your ESLint config:
+
+```js
+import reactCompiler from 'eslint-plugin-react-compiler'
+
+export default [
+ {
+ plugins: {
+ 'react-compiler': reactCompiler,
+ },
+ rules: {
+ 'react-compiler/react-compiler': 'error',
+ },
+ },
+]
+```
+
+Or, in the deprecated eslintrc config format:
+
+```js
+module.exports = {
+ plugins: [
+ 'eslint-plugin-react-compiler',
+ ],
+ rules: {
+ 'react-compiler/react-compiler': 'error',
+ },
+}
+```
+
+The ESLint plugin will display any violations of the rules of React in your editor. When it does this, it means that the compiler has skipped over optimizing that component or hook. This is perfectly okay, and the compiler can recover and continue optimizing other components in your codebase.
+
+
+**You don't have to fix all ESLint violations straight away.** You can address them at your own pace to increase the amount of components and hooks being optimized, but it is not required to fix everything before you can use the compiler.
+
+
+### Rolling out the compiler to your codebase {/*using-the-compiler-effectively*/}
+
+#### Existing projects {/*existing-projects*/}
+The compiler is designed to compile functional components and hooks that follow the [Rules of React](/reference/rules). It can also handle code that breaks those rules by bailing out (skipping over) those components or hooks. However, due to the flexible nature of JavaScript, the compiler cannot catch every possible violation and may compile with false negatives: that is, the compiler may accidentally compile a component/hook that breaks the Rules of React which can lead to undefined behavior.
+
+For this reason, to adopt the compiler successfully on existing projects, we recommend running it on a small directory in your product code first. You can do this by configuring the compiler to only run on a specific set of directories:
+
+```js {3}
+const ReactCompilerConfig = {
+ sources: (filename) => {
+ return filename.indexOf('src/path/to/dir') !== -1;
+ },
+};
+```
+
+When you have more confidence with rolling out the compiler, you can expand coverage to other directories as well and slowly roll it out to your whole app.
+
+#### New projects {/*new-projects*/}
+
+If you're starting a new project, you can enable the compiler on your entire codebase, which is the default behavior.
+
+### Using React Compiler with React 17 or 18 {/*using-react-compiler-with-react-17-or-18*/}
+
+React Compiler works best with React 19 RC. If you are unable to upgrade, you can install the extra `react-compiler-runtime` package which will allow the compiled code to run on versions prior to 19. However, note that the minimum supported version is 17.
+
+
+npm install react-compiler-runtime@beta
+
+
+You should also add the correct `target` to your compiler config, where `target` is the major version of React you are targeting:
+
+```js {3}
+// babel.config.js
+const ReactCompilerConfig = {
+ target: '18' // '17' | '18' | '19'
+};
+
+module.exports = function () {
+ return {
+ plugins: [
+ ['babel-plugin-react-compiler', ReactCompilerConfig],
+ ],
+ };
+};
+```
+
+### Using the compiler on libraries {/*using-the-compiler-on-libraries*/}
+
+React Compiler can also be used to compile libraries. Because React Compiler needs to run on the original source code prior to any code transformations, it is not possible for an application's build pipeline to compile the libraries they use. Hence, our recommendation is for library maintainers to independently compile and test their libraries with the compiler, and ship compiled code to npm.
+
+Because your code is pre-compiled, users of your library will not need to have the compiler enabled in order to benefit from the automatic memoization applied to your library. If your library targets apps not yet on React 19, specify a minimum [`target` and add `react-compiler-runtime` as a direct dependency](#using-react-compiler-with-react-17-or-18). The runtime package will use the correct implementation of APIs depending on the application's version, and polyfill the missing APIs if necessary.
+
+Library code can often require more complex patterns and usage of escape hatches. For this reason, we recommend ensuring that you have sufficient testing in order to identify any issues that might arise from using the compiler on your library. If you identify any issues, you can always opt-out the specific components or hooks with the [`'use no memo'` directive](#something-is-not-working-after-compilation).
+
+Similarly to apps, it is not necessary to fully compile 100% of your components or hooks to see benefits in your library. A good starting point might be to identify the most performance sensitive parts of your library and ensuring that they don't break the [Rules of React](/reference/rules), which you can use `eslint-plugin-react-compiler` to identify.
+
+## Usage {/*installation*/}
+
+### Babel {/*usage-with-babel*/}
+
+
+npm install babel-plugin-react-compiler@beta
+
+
+The compiler includes a Babel plugin which you can use in your build pipeline to run the compiler.
+
+After installing, add it to your Babel config. Please note that it's critical that the compiler run **first** in the pipeline:
+
+```js {7}
+// babel.config.js
+const ReactCompilerConfig = { /* ... */ };
+
+module.exports = function () {
+ return {
+ plugins: [
+ ['babel-plugin-react-compiler', ReactCompilerConfig], // must run first!
+ // ...
+ ],
+ };
+};
+```
+
+`babel-plugin-react-compiler` should run first before other Babel plugins as the compiler requires the input source information for sound analysis.
+
+### Vite {/*usage-with-vite*/}
+
+If you use Vite, you can add the plugin to vite-plugin-react:
+
+```js {10}
+// vite.config.js
+const ReactCompilerConfig = { /* ... */ };
+
+export default defineConfig(() => {
+ return {
+ plugins: [
+ react({
+ babel: {
+ plugins: [
+ ["babel-plugin-react-compiler", ReactCompilerConfig],
+ ],
+ },
+ }),
+ ],
+ // ...
+ };
+});
+```
+
+### Next.js {/*usage-with-nextjs*/}
+
+Please refer to the [Next.js docs](https://nextjs.org/docs/canary/app/api-reference/next-config-js/reactCompiler) for more information.
+
+### Remix {/*usage-with-remix*/}
+Install `vite-plugin-babel`, and add the compiler's Babel plugin to it:
+
+
+npm install vite-plugin-babel
+
+
+```js {2,14}
+// vite.config.js
+import babel from "vite-plugin-babel";
+
+const ReactCompilerConfig = { /* ... */ };
+
+export default defineConfig({
+ plugins: [
+ remix({ /* ... */}),
+ babel({
+ filter: /\.[jt]sx?$/,
+ babelConfig: {
+ presets: ["@babel/preset-typescript"], // if you use TypeScript
+ plugins: [
+ ["babel-plugin-react-compiler", ReactCompilerConfig],
+ ],
+ },
+ }),
+ ],
+});
+```
+
+### Webpack {/*usage-with-webpack*/}
+
+A community Webpack loader is [now available here](https://github.com/SukkaW/react-compiler-webpack).
+
+### Expo {/*usage-with-expo*/}
+
+Please refer to [Expo's docs](https://docs.expo.dev/preview/react-compiler/) to enable and use the React Compiler in Expo apps.
+
+### Metro (React Native) {/*usage-with-react-native-metro*/}
+
+React Native uses Babel via Metro, so refer to the [Usage with Babel](#usage-with-babel) section for installation instructions.
+
+### Rspack {/*usage-with-rspack*/}
+
+Please refer to [Rspack's docs](https://rspack.dev/guide/tech/react#react-compiler) to enable and use the React Compiler in Rspack apps.
+
+### Rsbuild {/*usage-with-rsbuild*/}
+
+Please refer to [Rsbuild's docs](https://rsbuild.dev/guide/framework/react#react-compiler) to enable and use the React Compiler in Rsbuild apps.
+
+## Troubleshooting {/*troubleshooting*/}
+
+To report issues, please first create a minimal repro on the [React Compiler Playground](https://playground.react.dev/) and include it in your bug report. You can open issues in the [facebook/react](https://github.com/facebook/react/issues) repo.
+
+You can also provide feedback in the React Compiler Working Group by applying to be a member. Please see [the README for more details on joining](https://github.com/reactwg/react-compiler).
+
+### What does the compiler assume? {/*what-does-the-compiler-assume*/}
+
+React Compiler assumes that your code:
+
+1. Is valid, semantic JavaScript.
+2. Tests that nullable/optional values and properties are defined before accessing them (for example, by enabling [`strictNullChecks`](https://www.typescriptlang.org/tsconfig/#strictNullChecks) if using TypeScript), i.e., `if (object.nullableProperty) { object.nullableProperty.foo }` or with optional-chaining `object.nullableProperty?.foo`.
+3. Follows the [Rules of React](https://react.dev/reference/rules).
+
+React Compiler can verify many of the Rules of React statically, and will safely skip compilation when it detects an error. To see the errors we recommend also installing [eslint-plugin-react-compiler](https://www.npmjs.com/package/eslint-plugin-react-compiler).
+
+### How do I know my components have been optimized? {/*how-do-i-know-my-components-have-been-optimized*/}
+
+[React Devtools](/learn/react-developer-tools) (v5.0+) has built-in support for React Compiler and will display a "Memo ✨" badge next to components that have been optimized by the compiler.
+
+### Something is not working after compilation {/*something-is-not-working-after-compilation*/}
+If you have eslint-plugin-react-compiler installed, the compiler will display any violations of the rules of React in your editor. When it does this, it means that the compiler has skipped over optimizing that component or hook. This is perfectly okay, and the compiler can recover and continue optimizing other components in your codebase. **You don't have to fix all ESLint violations straight away.** You can address them at your own pace to increase the amount of components and hooks being optimized.
+
+Due to the flexible and dynamic nature of JavaScript however, it's not possible to comprehensively detect all cases. Bugs and undefined behavior such as infinite loops may occur in those cases.
+
+If your app doesn't work properly after compilation and you aren't seeing any ESLint errors, the compiler may be incorrectly compiling your code. To confirm this, try to make the issue go away by aggressively opting out any component or hook you think might be related via the [`"use no memo"` directive](#opt-out-of-the-compiler-for-a-component).
+
+```js {2}
+function SuspiciousComponent() {
+ "use no memo"; // opts out this component from being compiled by React Compiler
+ // ...
+}
+```
+
+
+#### `"use no memo"` {/*use-no-memo*/}
+
+`"use no memo"` is a _temporary_ escape hatch that lets you opt-out components and hooks from being compiled by the React Compiler. This directive is not meant to be long lived the same way as eg [`"use client"`](/reference/rsc/use-client) is.
+
+It is not recommended to reach for this directive unless it's strictly necessary. Once you opt-out a component or hook, it is opted-out forever until the directive is removed. This means that even if you fix the code, the compiler will still skip over compiling it unless you remove the directive.
+
+
+When you make the error go away, confirm that removing the opt out directive makes the issue come back. Then share a bug report with us (you can try to reduce it to a small repro, or if it's open source code you can also just paste the entire source) using the [React Compiler Playground](https://playground.react.dev) so we can identify and help fix the issue.

In the example above, in the worst case (`setCard` → render → `setGoldCardCount` → render → `setRound` → render → `setIsGameOver` → render) there are three unnecessary re-renders of the tree below.
-Even if it weren't slow, as your code evolves, you will run into cases where the "chain" you wrote doesn't fit the new requirements. Imagine you are adding a way to step through the history of the game moves. You'd do it by updating each state variable to a value from the past. However, setting the `card` state to a value from the past would trigger the Effect chain again and change the data you're showing. Such code is often rigid and fragile.

In this case, it's better to calculate what you can during rendering, and adjust the state in the event handler:
