lodash-webpack-plugin

lodash-webpack-plugin v0.2.0

Create smaller Lodash builds by replacing feature sets of modules with noop, identity, or simpler alternatives.

This plugin complements babel-plugin-lodash by shrinking its cherry-picked builds even further!

Install

$ npm i --save lodash
$ npm i --save-dev lodash-webpack-plugin babel-core babel-loader babel-plugin-lodash babel-preset-es2015 webpack

Example

Usage

webpack.config.js

var LodashModuleReplacementPlugin = require('lodash-webpack-plugin');
var webpack = require('webpack');

module.exports = {
  'module': {
    'loaders': [{
      'loader': 'babel',
      'test': /\.js$/,
      'exclude': /node_modules/,
      'query': {
        'plugins': ['lodash'],
        'presets': ['es2015']
      }
    }]
  },
  'plugins': [
    new LodashModuleReplacementPlugin,
    new webpack.optimize.OccurenceOrderPlugin,
    new webpack.optimize.UglifyJsPlugin
  ]
};

Opt-in to features with an options object:

new LodashModuleReplacementPlugin({
  'collections': true,
  'paths': true
});
