Installation¶

npm¶

npm install @rbrowser/main react react-dom

yarn¶

yarn add @rbrowser/main react react-dom

pnpm¶

pnpm add @rbrowser/main react react-dom

React dependency¶

Package	Range
`react`	`^18.2.0 \\|\\| ^19.0.0`
`react-dom`	`^18.2.0 \\|\\| ^19.0.0`

Even if you only use mountBrowser() and never write a line of React yourself, you must install react / react-dom — the ESM build of @rbrowser/main (what npm consumers get) treats React as external. The example repo's package.json lists them under dependencies for exactly this reason.
