How do I compress HTML in laravel 5

Question

In Laravel 4.0, I use the code below to compress the HTML laravel response outputs to browser, however it doesn't work in laravel 5.

App::after(function($request, $response) {     if($response instanceof Illuminate\Http\Response)     {         $buffer = $response->getContent();         if(strpos($buffer,'<pre>') !== false)         {             $replace = array(                 '/<!--[^\[](.*?)[^\]]-->/s' => '',                 "/<\?php/"                  => '<?php ',                 "/\r/"                      => '',                 "/>\n</"                    => '><',                 "/>\s+\n</"                 => '><',                 "/>\n\s+</"                 => '><',             );         }         else         {             $replace = array(                 '/<!--[^\[](.*?)[^\]]-->/s' => '',                 "/<\?php/"                  => '<?php ',                 "/\n([\S])/"                => '$1',                 "/\r/"                      => '',                 "/\n/"                      => '',                 "/\t/"                      => '',                 "/ +/"                      => ' ',             );         }         $buffer = preg_replace(array_keys($replace), array_values($replace), $buffer);         $response->setContent($buffer);     } }); 

Please how do i make this work in Laravel 5.

OR

Please provide a better way of compressing HTML in laravel 5 if any. Thanks in advance.

NB: I don't wish to use any laravel package for compressing html, just need a simple code that does the work without killing performance.

Complete code is this (with custom GZip enabled) :

<?php  namespace App\Http\Middleware;  use Closure;  class OptimizeMiddleware {     /**      * Handle an incoming request.      *      * @param  \Illuminate\Http\Request  $request      * @param  \Closure  $next      * @return mixed      */     public function handle($request, Closure $next)     {         $response = $next($request);         $buffer = $response->getContent();         if(strpos($buffer,'<pre>') !== false)         {             $replace = array(                 '/<!--[^\[](.*?)[^\]]-->/s' => '',                 "/<\?php/"                  => '<?php ',                 "/\r/"                      => '',                 "/>\n</"                    => '><',                 "/>\s+\n</"                 => '><',                 "/>\n\s+</"                 => '><',             );         }         else         {             $replace = array(                 '/<!--[^\[](.*?)[^\]]-->/s' => '',                 "/<\?php/"                  => '<?php ',                 "/\n([\S])/"                => '$1',                 "/\r/"                      => '',                 "/\n/"                      => '',                 "/\t/"                      => '',                 "/ +/"                      => ' ',             );         }         $buffer = preg_replace(array_keys($replace), array_values($replace), $buffer);         $response->setContent($buffer);         ini_set('zlib.output_compression', 'On'); // If you like to enable GZip, too!         return $response;     } } 

Please check your browser network inspector for Content-Length header before/after implement this code.

enjoy it ... :).. .

It is not very good solution to minify html in middleware as you can spend a lot of CPU time on it and it runs on every request.

Instead it is better to use htmlmin package ( https://github.com/HTMLMin/Laravel-HTMLMin ):

composer require htmlmin/htmlmin php artisan vendor:publish 

Minifying HTML on blade template level and caching it in storage should be much more effective.
