React 19

[!NOTE] 🔐 As of January 26 2026, none of the React 19 security vulnerabilities affect Gatsby.

🚀 React 19 is here!

React 19 is now officially supported by Gatsby and all gatsby- packages maintained by the Gatsby team.

This is not a breaking change. You can safely upgrade to this release while staying on React 18.

All packages' peer dependencies on react and react-dom have been extended from ^18.0.0 to ^18.0.0 || ^19.0.0.

All existing stable Gatsby functionality is intended to now work with React 19.

PR: gatsbyjs/gatsby#39306

Upgrade Guide

[!WARNING] Community plugins may not have been updated yet to support React 19, so please check their repository for the current status. All plugins managed by the Gatsby team (in the gatsbyjs/gatsby repository) have been updated.

To upgrade to React 19, first upgrade gatsby and all your dependencies that start with gatsby- to the latest version. (Check out this guide if you need help with that.)

[!TIP] If you use npm 7 or higher you’ll want to use the --legacy-peer-deps option. For example, if you use gatsby and gatsby-plugin-postcss:

npm install --legacy-peer-deps gatsby@latest gatsby-plugin-postcss@latest

Then, follow the React 19 upgrade guide. No other changes are required.
