Learning Laravel. Where do you put this to make it work?

In Laravel 4.x you should put it into app\filters.php

In modern Laravel 5.x according to the docs you should put it into middleware (see "Before & After Middleware" section).

public function handle($request, Closure $next) {
        $response = $next($request);

        // HTML Minification
        ....................

        return $response;
}
