This package exposes a @preload
Blade directive that renders preload and prefetch links based on the contents in mix-manifest.json
. Declaring what should be preloaded or prefetched is simple, just make sure preload
or prefetch
is part of the chunk name.
If this is your mix manifest:
{ "/js/app.js": "/js/app.js", "/css/app.css": "/css/app.css", "/css/prefetch-otherpagecss.css": "/css/prefetch-otherpagecss.css", "/js/preload-biglibrary.js": "/js/preload-biglibrary.js", "/js/vendors~preload-biglibrary.js": "/js/vendors~preload-biglibrary.js" }
The following links will be rendered:
<link rel="prefetch" href="/css/prefetch-otherpagecss.css" as="style"> <link rel="preload" href="/js/preload-biglibrary.js" as="script"> <link rel="preload" href="/js/vendors~preload-biglibrary.js" as="script">

In addition to the above, you should set your config values appropriately to add or remove more assets from preload/prefetch
Support
Installation
You can install the package via composer:
composer require mkinyua53/laravel-mix-preload
Publish the config
php artisan vendor:publish --tag=preloader-config
Usage
Add a @preload
directive to your applications layout file(s).
<!doctype html> <html> <head> ... @preload </head> <body> ... </body> </html>
You can determine which scripts need to be preloaded or prefetched by making sure preload
or prefetch
is part of their file names. You can set the file name by creating a new entry in Mix, or by using dynamic imports.
Adding a second entry
By default, Laravel sets up Mix with a single app.js
entry. If you have another script outside of app.js
that you want to have preloaded, make sure preload
is part of the entry name.
mix .js('resources/js/app.js', 'public/js'); .js('resources/js/preload-maps.js', 'public/js');
If you want to prefetch the script instead, make sure prefetch
is part of the entry name.
mix .js('resources/js/app.js', 'public/js'); .js('resources/js/prefetch-maps.js', 'public/js');
Using dynamic imports with custom chunk names
If you want to preload a chunk of your application scripts, make sure preload
is part of the chunk name. You can use Webpack's magic webpackChunkName
comment to set the module's chunk name.
import('./maps' /* webpackChunkName: "preload-maps" */).then(maps => { maps.init(); });
The same applies to prefetching.
import('./maps' /* webpackChunkName: "prefetch-maps" */).then(maps => { maps.init(); });
