Using a bundler

Most people should start with a page in one file. If you already have Vite, you can import SvenJS like any ESM package.

npm install svenjs

In tsconfig.json (or Vite’s esbuild JSX settings):

{
  "compilerOptions": {
    "jsx": "react-jsx",
    "jsxImportSource": "svenjs"
  }
}

There is no separate svenjsx package. svenjs/jsx-runtime ships with the runtime.

A CDN / script-tag build is emitted as svenjs.iife.js for the original “drop it in a page” goal.
