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

2020-05-21 05:26:51 +08:00
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.
2018-02-21 22:21:05 +08:00
You can use
2014-07-24 17:29:49 +08:00
You can see the output files:
2019-04-09 02:29:40 +08:00
- `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`
2019-05-10 03:34:28 +08:00
- `406.js` is an additional chunk which is used by both pages. It contains:
2019-04-09 02:29:40 +08:00
- module `shared.js`
2014-07-24 17:29:49 +08:00
You can also see the info that is printed to console. It shows among others:
2019-04-09 02:29:40 +08:00
- the generated files
2020-03-27 10:50:58 +08:00
- the chunks with file, name, and id
2019-04-09 02:29:40 +08:00
- 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 `>`
