Just make sure to edit package.json, README.md and LICENSE files accordingly with your module's info.

Adding Features

```bash
npm i -D rollup rollup-plugin-babel rollup-plugin-babel-minify rollup-plugin-commonjs rollup-plugin-node-resolve rollup-plugin-replace rollup-watch
```

Add a rollup.config.js file in the root of the repository with the following contents:

import minify from "rollup-plugin-babel-minify";

module.exports = {
  input: "dist/index.js",
  plugins: [
    minify({
      comments: false
      // Any other options for babel-minify.
    })
  ]
};

Replace the build script/line in the package.json file with the following lines (make sure to replace the {YOUR_PKG_NAME} below with the actual name of your module):

"build": "npm run build:common-js && npm run build:umd && npm run build:umd:min",
"build:common-js": "babel src -d dist",
"build:umd": "node_modules/.bin/rollup src/index.js --file dist/{YOUR_PKG_NAME}.umd.js --format umd --name {YOUR_PKG_NAME}",
"build:umd:watch": "npm run build:umd -- --watch",
"build:umd:min": "node_modules/.bin/rollup src/index.js --file dist/{YOUR_PKG_NAME}.umd.min.js --config --format umd --compact --name {YOUR_PKG_NAME}",

Add appropriate entry points to your package.json file:

"browser": "dist/{YOUR_PKG_NAME}.umd.min.js",
"cdn": "dist/{YOUR_PKG_NAME}.umd.min.js",

```bash
yarn add -D @babel/preset-typescript @types/jest @typescript-eslint/eslint-plugin @typescript-eslint/parser typescript
```
