MoveToParentMergingPlugin

A simple merging plugin that attempts to lift modules required by several child chunks up to the parent chunk. This is mostly useful if you are code-splitting your bundles into one primary (entry) chunk and several smaller chunks that all have similar dependencies.

Modules will only be moved from a chunk if, for all chunks that contain that module, there is a common parent chunk.

There is a simple example in the repo to illustrate how this works.

Usage

Install with npm:

npm install move-to-parent-merging-webpack-plugin

Then, use as a plugin in your webpack.config.js:

var MoveToParentMergingPlugin = require('move-to-parent-merging-webpack-plugin');
 
module.exports = {
    
    ... your config ...
 
    plugins: [
        new MoveToParentMergingPlugin();
    ]
};

MoveToParentMerginPlugin([chunkCount])

The plugin can optionally take an argument that specifies how many chunks must contain a module for it to be considered "common" enough to be lifted to a parent chunk. Default = 2 (aggressive.)
