uniroll

Opinionated frontend compiler in browser.

  • Bundle in browser for rapid prototyping
  • Resolve modules by https://esm.sh
  • Transpile typescript

How it works

  • Create virtual fs by rollup-plugin-virtual-fs
  • Load npm modules via rollup-plugin-http-resolve
  • Compile with typescript
  • Compile with rollup

Run in browser

npm install uniroll typescript rollup --save
import { bundle } from "uniroll";
const files = {
  "/foo.tsx": "export default 1",
  "/index.tsx": "import foo from 'foo';\nconsole.log('hello', foo)",
};
const bundled = await bundle({
  files,
  input: "/index.tsx",
});
const out = await bundled.generate({ format: "esm" });
console.log(out.output[0]);

CLI

Run compiler with same logics.

$ npm install uniroll-tools -g
$ uniroll foo.js -o out.js
