Laravel Mix - Merge Manifest
This extension supports multi mix configration without overwriting the mix-manifest.json file. It merges new manifests into the existing one.
Usage
First, install the extension.
// Laravel Mix v5
npm install laravel-mix-merge-manifest@v1 --save-dev
// Laravel Mix v6
npm install laravel-mix-merge-manifest@v2 --save-dev
Then, require it within your webpack.mix.js file, like so:
let mix = require('laravel-mix');
require('laravel-mix-merge-manifest');
mix
.js('resources/assets/js/app.js', 'public/js')
.less('resources/assets/less/app.less', 'public/css')
.mergeManifest();
Examples - Laravel Mix v6
Running Laravel Mix with different configurations
Laravel Mix only supports a global configuration. If you want to use diffent configurations - e.g. to provide a separate JS file for legacy browsers - you need to run mix multiple times with different configs.
npx mix && npx mix --mix-config=webpack.legacy.mix.js
Your default configuration in webpack.mix.js could look like this:
// ...
mix.js('resources/assets/scripts/main.js', 'scripts')
.mergeManifest()
// ...
And your legacy configuration in webpack.legacy.mix.js would use .mergeManifest():
// ...
mix
.babel({ ... }) // Different Babel Configuration
.js('resources/assets/scripts/main.js', 'scripts/main.legacy.js')
.mergeManifest()
// ...
Extracting multiple vendors
npx mix --mix-config=webpack.backoffice.mix.js && npx mix --mix-config=webpack.customers.mix.js
webpack.backoffice.mix.js
mix
.js('resources/js/backoffice/backoffice.js', 'public/js/backoffice')
.extract(['jquery', 'bootstrap', 'lodash', 'popper.js'])
.mergeManifest()
webpack.customers.mix.js
mix
.js('resources/js/customers/customers.js', 'public/js/customers')
.extract(['vue'])
.mergeManifest()
