I'd like to split my vendor code into two chunks, one that contains all angular libraries, and another that contains everything else.
My angular app has a single entry point and is setup something like:
entry: {
app: './path_to/app.js',
vendor: ['jquery', 'moment', 'numeral'],
'vendor.angular': ['angular', 'angular-route', 'angular-numeraljs']
}
I then use the CommonsChunkPlugin to configure the two other bundles:
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
chunks: ['app'],
warnings: false,
filename: 'vendor.bundle.js'
})
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor.angular',
chunks: ['app'],
warnings: false,
filename: 'vendor.angular.bundle.js'
})
This generates 3 files:
Version: webpack 1.13.1
Time: 12719ms
Asset Size Chunks Chunk Names
app.bundle.js 19.2 kB 0 [emitted] app
vendor.bundle.js 484 kB 1 [emitted] vendor
vendor.angular.bundle.js 652 kB 2 [emitted] vendor.angular
[0] multi vendor.angular 124 bytes {2} [built]
[0] multi vendor 88 bytes {1} [built]
+ 124 hidden modules
app.bundle.js contains just my app code.
vendor.bundle.js contains all 3rd party libs excluding angular stuff
vendor.angular.bundle.js contains all angular stuff AND all my 3rd party libs that are already inside of vendor.bundle.js.
Is there anyway to have JUST the angular modules bundled in vendor.angular.bundle.js, without automatically including the other 3rd party libs?
Code splitting is one of the most compelling features of webpack. This feature allows you to split your code into various bundles which can then be loaded on demand or in parallel.
In React, code splitting involves applying the dynamic import() syntax to your components so that webpack automatically split the imported component as a separate bundle.
Bundle splitting is the process of separating Javascript code into multiple files. This results in a smaller amount of code being downloaded on the initial page load while other parts of the web app are loaded later on demand.
Figured this out:
The order of the CommonsChunkPlugin's matter in the plugins array.
To get the desired 'chunking', here's the change I had to make:
The updated CommonsChunkPlugins now looks like:
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor.angular',
chunks: ['app'],
warnings: false,
filename: 'vendor.angular.bundle.js'
})
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
chunks: ['vendor.angular'],
warnings: false,
filename: 'vendor.bundle.js'
})
The above now yields:
Version: webpack 1.13.1
Time: 7451ms
Asset Size Chunks Chunk Names
app.bundle.js 19.2 kB 0 [emitted] app
vendor.bundle.js 484 kB 1 [emitted] vendor
vendor.angular.bundle.js 221 kB 2 [emitted] vendor.angular
[0] multi vendor.angular 124 bytes {2} [built]
[0] multi vendor 88 bytes {1} [built]
+ 124 hidden modules
Running:
webpack --progress --display-modules --display-chunks -v
I'm able to verify that all angular related modules are now in the vendor.angular.bundle.js, and all non-angular modules are indeed in vendor.bundle.js
