Plug'n'Play package.json webpack plugin

A webpack plugin to generate a package.json file with external modules as dependencies

Inspired by generate-package-json-webpack-plugin

Install

yarn add --dev pnp-package-json-webpack-plugin

Usage

This plugin generates a package.json asset from modules marked in externals with pinned versions using resolutions from the PnP API. This allows for lightweight, mostly-stable builds in Yarn workspace environments.

In your webpack configuration:

const PnpPackageJsonPlugin = require('pnp-package-json-webpack-plugin');
 
const basePackageValues = {
  name: 'my-nodejs-module',
  version: '1.0.0',
  main: './index.js',
  engines: {
    node: '>= 14.0.0',
  },
};
 
module.exports = {
  // ...
  plugins: [
    new PnpPackageJsonPlugin({
      basePackageValues,
    }),
  ],
};

Please be aware that the file created should not be viewed as a replacement for a lockfile such as yarn.lock. The version of each external pinned by the plugin will be stable, but it offers no control over child dependencies installed later.
