Webpack Manifest Plugin

Webpack plugin for generating an asset manifest.

NOTE: The following is related to the next major version of webpack-manifest-plugin, please check https://github.com/danethurber/webpack-manifest-plugin/blob/1.x/README.md for v1 documentation

Install

npm install --save-dev webpack-manifest-plugin

Usage

In your webpack.config.js

var ManifestPlugin = require('webpack-manifest-plugin');

module.exports = {
    // ...
    plugins: [
      new ManifestPlugin()
    ]
};

This will generate a manifest.json file in your root output directory with a mapping of all source file names to their corresponding output file, for example:

{
  "mods/alpha.js": "mods/alpha.1234567890.js",
  "mods/omega.js": "mods/omega.0987654321.js"
}

API:

// webpack.config.js

module.exports = {
  output: {
    publicPath
  },
  plugins: [
    new ManifestPlugin(options)
  ]
}
