Installation

Firstly, you'll need to make sure that you have React and React DOM installed. Easy Peasy v7 requires React 19 or later — it relies on useSyncExternalStore, useTransition, useDeferredValue, useOptimistic, use, and Suspense integration provided by React 19.

npm install react
npm install react-dom

Then install Easy Peasy. While v7 is in beta it is published under the beta dist-tag, so install it explicitly:

npm install easy-peasy@beta

The latest tag will move to v7 once the stable release ships, at which point npm install easy-peasy will pick up v7 by default.

If you are still on React 18, stay on easy-peasy@^6 — see the v6 → v7 migration guide for details on upgrading.

We're off to the races!
