This plugin used to be called rollup-plugin-npm
Locate modules using the Node resolution algorithm, for using third party modules in node_modules
npm install --save-dev rollup-plugin-node-resolveimport { rollup } from 'rollup';

entry: 'main.js',

nodeResolve({
// use "jsnext:main" if possible
// – see https://github.com/rollup/rollup/wiki/jsnext:main
jsnext: true, // Default: false
// use "main" field or index.js, even if it's not an ES6 module
// (needs to be converted from CommonJS to ES6
// – see https://github.com/rollup/rollup-plugin-commonjs
main: true, // Default: true
// if there's something your bundle requires that you DON'T
// want to include, add it to 'skip'. Local and relative imports
// can be skipped by giving the full filepath. E.g.,
// `path.resolve('src/relative-dependency.js')`
skip: [ 'some-big-dependency' ], // Default: []
// some package.json files have a `browser` field which
// specifies alternative files to load for people bundling
// for the browser. If that's you, use this option, otherwise
// pkg.browser will be ignored
browser: true, // Default: false
// not all files you want to resolve are .js files
extensions: [ '.js', '.json' ], // Default: ['.js']
// whether to prefer built-in modules (e.g. `fs`, `path`) or
// local ones with the same names
preferBuiltins: false // Default: true
