multiple-entry-points

README.md

This example shows how to use multiple entry points with a commons chunk.

In this example, you have two (HTML) pages pageA and pageB. You want to create individual bundles for each page. In addition to this, you want to create a shared bundle that contains all the modules used in both pages (assuming there are many/big modules in common). The pages also use Code Splitting to load a less used part of the features on demand.

You can see how to define multiple entry points via the entry option.

You can use

You can see the output files:

  • commons.js contains:
    • module common.js which is used in both pages
  • pageA.js contains: (pageB.js is similar)
    • the module system
    • chunk loading logic
    • the entry point pageA.js
    • it would contain any other module that is only used by pageA
  • 406.js is an additional chunk which is used by both pages. It contains:
    • module shared.js

You can also see the info that is printed to console. It shows among others:

  • the generated files
  • the chunks with file, name, and id
    • see lines starting with chunk
  • the modules that are in the chunks
  • the reasons why the modules are included
  • the reasons why a chunk is created
    • see lines starting with >

pageA.js

var common = require("./common");
require(["./shared"], function(shared) {
	shared("This is page A");
});

pageB.js

var common = require("./common");
require.ensure(["./shared"], function(require) {
	var shared = require("./shared");
	shared("This is page B");
});

webpack.config.js

module.exports = {
	// mode: "development || "production",
	entry: {
		pageA: "./pageA",
		pageB: "./pageB"
	},
	optimization: {
		splitChunks: {
			cacheGroups: {
				commons: {
					name: "commons",
					chunks: "initial",
					minChunks: 2,
					minSize: 0
				}
			}
		},
		chunkIds: "deterministic" // To keep filename consistent between different modes (for example building only)
	}
};
