This repo contains a bare-bones example of how to create a library using Rollup, including importing a module from node_modules and converting it from CommonJS.
Clone this repository and install its dependencies:
git clone https://github.com/gyx8899/lib-template
cd lib-template
npm installnpm run build builds the library to dist, generating three files:
dist/index.cjs.jsA CommonJS bundle, suitable for use in Node.js, thatrequires the external dependency. This corresponds to the"main"field in package.jsondist/index.esm.jsan ES module bundle, suitable for use in other people's libraries and applications, thatimports the external dependency. This corresponds to the"module"field in package.jsondist/index.umd.jsa UMD build, suitable for use in any environment (including the browser, as a<script>tag), that includes the external dependency. This corresponds to the"browser"field in package.json
npm run dev builds the library, then keeps rebuilding it whenever the source files change using rollup-watch.
npm test builds the library, then tests it.
