Rollup scripts is a "zero config" bundler for JavaScript and TypeScript libraries.

Rollup scripts is designed to work out of the box for majority of JS and TS projects. It wraps the core functionality of Rollup in a smart way, therefore eliminating the need for setting up projects and configurations from scratch.

1. Create an npm project

npm init -y

2. Install rollup-scripts. NOTE: Do not install this package globally!

npm i -D --save-exact rollup-scripts

3. If you are testing a forked repository:

npm i -D --save-exact github:{your username}/rollup-scripts

4. Create an src folder and an entry file index.js with a valid JavaScript code.

mkdir src
touch src/index.mjs

5. Update package.json file as follows

{
  "main": "dist/umd/index.js",
  "module": "dist/esm/index.mjs",
  "scripts": {
    "build": "rollup-scripts build",
    "lint": "rollup-scripts lint",
    "init": "rollup-scripts init"
  }
}

6. Run command npm run build to compile the code.

Rollup scripts currently supports compilation for JavaScript, TypeScript, React and Preact projects. We are working to add support for Angular, Vue and Svelte projects as well.

npx rollup-scripts build

Rollup-scripts supports init, build and lint scripts. For more details run:

npx rollup-scripts --help
