rollup-plugin-auto-external

Rollup plugin to automatically exclude package.json dependencies and peerDependencies from your bundle.

Install

npm install --save-dev rollup-plugin-auto-external

Usage

Example rollup.config.js

import autoExternal from 'rollup-plugin-auto-external';

export default {
  input: 'index.js',
  plugins: [autoExternal()],
};

Example rollup.config.js with options

import path from 'path';
import autoExternal from 'rollup-plugin-auto-external';

export default {
  input: 'index.js',
  plugins: [
    autoExternal({
      builtins: false,
      dependencies: true,
      packagePath: path.resolve('./packages/module/package.json'),
      peerDependencies: false,
    }),
  ],
};

Example rollup.config.js with external

rollup-plugin-auto-external does not overwrite the external option. The two can happily coexist.

import autoExternal from 'rollup-plugin-auto-external';

export default {
  input: 'index.js',
  external: id => id.includes('babel-runtime'),
  plugins: [autoExternal()],
};

Example rollup.config.js with per format options

import autoExternal from 'rollup-plugin-auto-external';

export default ['es', 'umd'].map(format => ({
  input: 'index.js',
  plugins: [
    autoExternal({
      dependencies: format === 'es',
    }),
  ],
}));

Options

builtins

boolean|string: defaults to true. Add all Node.js builtin modules (in the running version) as externals. Specify a string value (e.g., '6.0.0') to add all builtin modules for a specific version of Node.js.

Rollup will complain if builtins is present, and the build target is a browser. You may want rollup-plugin-node-builtins.

dependencies

boolean: defaults to true.

packagePath

string: defaults to process.cwd(). Path to a package.json file or its directory.

peerDependencies

boolean: defaults to true.
