5.0.1 (2022-04-12)

Create React App 5.0.1 is a maintenance release that improves compatibility with React 18. We've also updated our templates to use createRoot and relaxed our check for older versions of Create React App.

Migrating from 5.0.0 to 5.0.1

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

npm install --save --save-exact react-scripts@5.0.1

or

yarn add --exact react-scripts@5.0.1

5.0.0 (2021-12-14)

Create React App 5.0 is a major release with several new features and the latest version of all major dependencies.

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

Highlights

• webpack 5 (#11201)
• Jest 27 (#11338)
• ESLint 8 (#11375)
• PostCSS 8 (#11121)
• Fast Refresh improvements and bug fixes (#11105)
• Support for Tailwind (#11717)
• Improved package manager detection (#11322)
• Unpinned all dependencies for better compatibility with other tools (#11474)
• Dropped support for Node 10 and 12

Migrating from 4.0.x to 5.0.0

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

npm install --save --save-exact react-scripts@5.0.0

or

yarn add --exact react-scripts@5.0.0

NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running npm install (or yarn) 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@5.0.0` 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.

Dropped support for Node 10 and 12 Node 10 reached End-of-Life in April 2021 and Node 12 will be End-of-Life in April 2022. Going forward we will only support the latest LTS release of Node.js.
