@rollup/plugin-auto-install

🍣 A Rollup plugin which automatically installs dependencies that are imported by a bundle, even if not yet in package.json.

Requirements

This plugin requires an LTS Node version (v14.0.0+) and Rollup v1.20.0+.

Install

Using npm:

npm install @rollup/plugin-auto-install --save-dev

Usage

Create a rollup.config.js configuration file and import the plugin:

import auto from '@rollup/plugin-auto-install';
import resolve from '@rollup/plugin-node-resolve';

export default {
  input: 'src/index.js',
  output: {
    dir: 'output',
    format: 'cjs'
  },
  plugins: [auto(), resolve()]
};

Note: ensure that this plugin is added to the plugins array before @rollup/plugin-node-resolve.

Then call rollup either via the CLI or the API.

Options

`pkgFile`

Type: String Default: '{cwd}/package.json'

Specifies the location on disk of the target package.json file. If the file doesn't exist, it will be created by the plugin, as package managers need to populate the dependencies property.

`manager`

Type: 'pnpm'|'yarn'|'npm' Default: determined at runtime

Specifies the package manager to use. If not specified:

'pnpm' if pnpm-lock.yaml exists
'yarn' if yarn.lock exists
'npm' otherwise
