Installation

Last updated 2026-10-09

Requirements: Node.js 20.19 or newer (the generated project's tooling needs it) and npm 10 or newer. The runtime packages @rheajs/core and @rheajs/cli declare node >=20.

npx create-rhea my-api
cd my-api
npm install
npm run dev

create does not install dependencies unless you pass --install. It refuses to write into a non-empty directory.

Check your setup at any time:

npx rhea doctor
npx rhea info
