Laravel Page Speed

Simple package to minify HTML output on demand which results in a 35%+ optimization.

Installation

You can install the package via composer:

$ composer require renatomarinho/laravel-page-speed

Laravel 5.5 and up

Laravel 5.5 and up uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider.

Laravel 5.4 or 5.3

Add the Service Provider to the providers array in config/app.php:

RenatoMarinho\LaravelPageSpeed\ServiceProvider::class

This is required for publishing the configuration file:

Publish configuration file

php artisan vendor:publish --provider="RenatoMarinho\LaravelPageSpeed\ServiceProvider"

Do not forget to register middlewares

Next, the \RenatoMarinho\LaravelPageSpeed\Middleware\CollapseWhitespace::class and other middleware must be registered in the kernel:

//app/Http/Kernel.php

protected $middleware = [
    ...
    \RenatoMarinho\LaravelPageSpeed\Middleware\InlineCss::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\ElideAttributes::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\InsertDNSPrefetch::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\RemoveComments::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\TrimUrls::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\RemoveQuotes::class,
    \RenatoMarinho\LaravelPageSpeed\Middleware\CollapseWhitespace::class,
]

Configuration

After installing package, you may need to configure some options.

Disable Service

You would probably like to set up the local environment to get a readable output.

//config/laravel-page-speed.php

//Set this field to false to disable the laravel page speed service.
'enable' => env('LARAVEL_PAGE_SPEED_ENABLE', true),

Skip routes

You would probably like to configure the package to skip some routes.

//config/laravel-page-speed.php

//You can use * as wildcard.
'skip' => [
    '*.pdf', //Ignore all routes with final .pdf
    '*/downloads/*',//Ignore all routes that contain 'downloads'
    'assets/*', // Ignore all routes with the 'assets' prefix
];

By default this field comes configured with some options, so feel free to configure according to your needs...

Notice: This package skip automatically 'binary' and 'streamed' responses. See File Downloads.

Warning

\RenatoMarinho\LaravelPageSpeed\Middleware\TrimUrls::class is considered medium risk. It can cause problems if it uses the wrong base URL. This can happen, for example, if you serve HTML that will be pasted verbatim into other HTML pages. If URLs are trimmed on the first page, they will be incorrect for the page they are inserted into. In this case, just disable the middleware.

Testing

$ composer test
