Laravel Mix Code Splitter

---

Definition from google

---

#### _"Modern sites often combine all of their JavaScript into a single, large bundle. ... An alternative to large bundles is code-splitting, which is where JavaScript is split into smaller chunks. This enables sending the minimal code required to provide value upfront, improving page-load times. The rest can be loaded on demand."_

---


---

Setup

---

1. webpack.mix.js

---

`js
let mix = require('laravel-mix');
require('laravel-mix-code-splitter');

/ Normally, we create a single global file -- available on all pages /
mix.js('resources/js/app.js', 'public/js/app.js')

/*----------------------------------------------------------
| Code splitting allows us to "split" our code up.
*----------------------------------------------------------
|
| -> resources
| . /js/split/home.js
| . /js/split/badges.js
| . /js/split/invoices.js
|
*/
.split(mix.js, 'resources/js/split', 'public/js/split')

/*----------------------------------------------------------------------------
| Providing splits of our code for each page or feature specific page
*----------------------------------------------------------------------------
|
| -> public
| . /js/split/home.js
| . /js/split/badges.js
| . /js/split/invoices.js
|
*/
`

_After_ mix does its thing, there's _multitudes_ of ways to dynamically load the proper split for the current route ~ here's a simpler implementation I personally like

---

routes/web.php

---

_Add names to your routes, we'll use resourceful routes to speed the example up_

---

`php
Route::resource('home', 'HomeController')->home('home');
Route::resource('badges', 'BadgesController')->name('badges');
Route::resource('invoices', 'InvoiceController')->name('invoices');
`

---

_Add snippet to your primary layout blade file_

---

resources/views/layouts/app.blade.php

---

- First we load our js (app.js)
- Then we check if there is a code split
- If there is a code split for the current route resource group, we load it

`php

@if (asset( "js/split". Str::of(Route::currentRouteName())->before('.')->append('.js') ))

@endif
`


---

home.js loads on visits to

---

- /home
- /home/{id}
- /home/create
- /home/{id}/edit

---

badges.js loads on visits to

---

- /badges
- /badges/{id}
- /badges/create
- /badges/{id}/edit

---

invoices.js loads on visits to

---

- /invoices
- /invoices/{id}
- /invoices/create
- /invoices/{id}/edit

---

app.js loads on every page

---


---

Code splitting non-js files

---


`js
let mix = require('laravel-mix');
require('laravel-mix-code-splitter');

mix

.js('resources/js/app.js', 'public/js/app.js')
.split(mix.js, 'resources/js/split', 'public/js/split')


.css('resources/js/app.css', 'public/css/app.css')
.split(mix.css, 'resources/css/split', 'public/css/split')

.css('resources/js/app.css', 'public/css/app.css')
.split(mix.css, 'resources/css/split', 'public/css/split')

.postCss('resources/css/main.css', 'public/css', [require('precss')()])
.split(mix.postCss, 'resources/css', 'public/css/split', [require('precss')()])

// etc...
