Split vendor bundle


My vendor bundle is getting really big and I want to split into 2 parts. (One part with all the react related packages, and the other with the rest of the packages).

What I currently have to create the vendor bundle is:

new webpack.optimize.CommonsChunkPlugin({
  name: ['vendor'],
  filename: '[name].bundle.js',
  minChunks: module => module.context.includes('node_modules')
})

I tried adding these different approaches below, but no success so far:

// approach 1
new webpack.optimize.CommonsChunkPlugin({
  name: 'react',
  chunks: ['vendor'],
  minChunks: ({resource}) => (/node_modules\/react/).test(resource)
})

// approach 2
new webpack.optimize.CommonsChunkPlugin({
  name: ['react'],
  filename: '[name].bundle.js',
  minChunks: ({resource}) => (/node_modules\/react/).test(resource)
})

The split happens, but I cannot run in the browser. In my console I get:

vendor.bundle.js:1 Uncaught ReferenceError: webpackJsonp is not defined
at vendor.bundle.js:1

(anonymous) @ vendor.bundle.js:1

I've already loaded the new file with the tag in my html.


Solution

  • I just solved the issue using the following solution:

    new webpack.optimize.CommonsChunkPlugin({
      name: ['vendor'],
      filename: '[name].bundle.js',
      minChunks: module => module.context.includes('node_modules') && !module.request.includes('scss')
    }),
    
    new webpack.optimize.CommonsChunkPlugin({
      name: 'react',
      chunks: ['vendor'],
      minChunks: ({resource}) => (/node_modules\/react/).test(resource)
    }),
