## 4.0.0 (2020-10-23)

Create React App 4.0 is a major release with several new features, including support for Fast Refresh!

Thanks to all the maintainers and contributors who worked so hard on this release! :raised_hands:

# Highlights

- Fast Refresh [#8582](https://github.com/facebook/create-react-app/pull/8582)
- React 17 support
  - New JSX transform [#9645](https://github.com/facebook/create-react-app/pull/9645)
- TypeScript 4 support [#9734](https://github.com/facebook/create-react-app/pull/9734)
- ESLint 7 [#8978](https://github.com/facebook/create-react-app/pull/8978)
  - New Jest and React Testing Library rules [#8963](https://github.com/facebook/create-react-app/pull/8963)
- Jest 26 [#8955](https://github.com/facebook/create-react-app/pull/8955)
- PWA/workbox improvements
  - Switch to the Workbox InjectManifest plugin [#9205](https://github.com/facebook/create-react-app/pull/9205)
  - Now its own template so it can be released independently
- Web Vitals support [#9116](https://github.com/facebook/create-react-app/pull/9116)

# Migrating from 3.4.x to 4.0.0

Inside any created project that has not been ejected, run:

```bash
npm install --save --save-exact react-scripts@4.0.0
```

or

```
yarn add --exact react-scripts@4.0.0
```

**NOTE: You may need to delete your `node_modules` folder and reinstall your dependencies by running `yarn` (or `npm install`) if you encounter errors after upgrading.**

If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.

## Breaking Changes

Like any major release, `react-scripts@4.0.0` contains a number of breaking changes. We expect that they won't affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.

### ESLint

We've upgraded to ESLint 7 and added many new rules including some for Jest and React Testing Library as well as the `import/no-anonymous-default-export` rule. We've also upgraded `eslint-plugin-hooks` to version 4.0.0 and removed the `EXTEND_ESLINT` flag as it is no longer required to customize the ESLint config.

### Jest

We've upgraded to Jest 26 and now set `resetMocks` to `true` by default in the Jest config.

### Service workers

We've switched to the Workbox InjectManifest plugin and moved the PWA templates into their own [repository](https://github.com/cra-template/pwa).

### Removed `typescript` flag and `NODE_PATH` support

We've removed the deprecated `typescript` flag when creating a new app. Use `--template typescript` instead. We've also dropped deprecated `NODE_PATH` flag as this has been replaced by setting the base path in `jsconfig.json`.

### Fix dotenv file loading order

We've changed the loading order of env files to match the `dotenv` specification. See #9037 for more details.

### Dropped Node 8 support

Node 8 reached End-of-Life at the end of 2019 and is no longer supported.
