LimitChunkCountPlugin

While writing your code, you may have already added many code split points to load stuff on demand. After compiling you might notice that some chunks are too small - creating larger HTTP overhead. LimitChunkCountPlugin can post-process your chunks by merging them.

new webpack.optimize.LimitChunkCountPlugin({
  // Options...
});

Options

The following options are supported:

maxChunks

number

Limit the maximum number of chunks using a value greater than or equal to 1. Using 1 will prevent any additional chunks from being added as the entry/main chunk is also included in the count.

webpack.config.js

const webpack = require('webpack');
module.exports = {
  // ...
  plugins: [
    new webpack.optimize.LimitChunkCountPlugin({
      maxChunks: 5
    })
  ]
};

minChunkSize

Keeping chunk size above the specified limit is no longer a feature of this plugin. Use MinChunkSizePlugin instead.

Usage via CLI

This plugin and it's options can also be invoked via the CLI:

webpack --optimize-max-chunks 15
