Inline Chunks Webpack Plugin

webpack v4 support

This is a webpack plugin that inline your chunks that is written as link or script using HtmlWebpackPlugin.

It both can be use to inline manifest & css within link or script tag to save a http request.

It also can inline any other chunks.

This plugin requires HtmlWebpackPlugin v2.10.0 and above.

Installation

Install the plugin with npm:

npm install inline-chunks-html-webpack-plugin --save-dev

Configuration

• inlineChunks: An array of names of chunk to inline.
  • chunk[.ext]: .ext is optional to distinguish chunk of the same name from the file extension.
• deleteFile: delete file from asset default to false.

//webpack.config
const InlineChunksWebpackPlugin = require('inline-chunks-html-webpack-plugin');
module.exports = {
    //.....
    //.....
    plugins: [
      //...
      //...
      new InlineChunksWebpackPlugin({
        inlineChunks: ['manifest'],
        deleteFile: true // do not build chunks
      })
    //...
    ]
    //.....
    //.....
}

Example Usage

Webpack's runtime changes with every build. For effective long-term caching, we separate the runtime code in manifest.js. This manifest.js is very small and increases our startup time as it is a separate http request. Inlining the generated manifest.js in the index.html is a solution.

Extract css bundle and split webpack runtime to manifest then inline it.

// for explicit vendor chunk config
{
  entry: {
    app: './main.js',
    vendor: ['react','redux']
  },
  output: {
    path: path.join(__dirname, "js"),
    filename: "[name].[chunkhash].js",
    chunkFilename: "[chunkhash].js"
  },
  plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor'
    }),
    new webpack.optimize.CommonsChunkPlugin({
      name: 'manifest',
      chunks: ['vendor']
    }),
    // extract css into its own file
    new ExtractTextPlugin('[name].[contenthash].css'),
    new HtmlWebpackPlugin({
      // your options
    }),
    new InlineChunksWebpackPlugin({
      // inlined app.css to the head and manifest.js to the body
      inlineChunks: ['manifest', 'app.css'],
      deleteFile: true
	})
  ]
}
