SPINEN's Laravel Browser Filter

This is a Laravel 5 middleware to filter routes based on browser types.

We specify the browsers that we are going to support at the beginning of a project, so this package makes sure that the visitor is using a supported browser.

Prerequisites

NOTE: If you need to use PHP <7.2 or Laravel <5.2, please stay with version 1.x

As side from Laravel >= 5.5, there are 2 packages that are required:

• mobiledetect - To get the user agent string. This package is not needed to get to the user agent string, but there are other features that I plan on using in the future so I kept it installed.
• ua-parser PHP Library - To parse the user agent string

Install

Install Browser Filter:

$ composer require spinen/laravel-browser-filter

The package uses the auto registration feature of Laravel 5.

'providers' => [
    // ...
    Spinen\BrowserFilter\FilterServiceProvider::class,
];

Register the middleware

The middleware needs to be registered with the Kernel to allow it to parse the request.

Register the HTTP Stack Middleware for the web group in app/Http/Kernel.php:

    protected $middlewareGroups = [
        'web' => [
            // ..
            \Spinen\BrowserFilter\Stack\Filter::class,
        ],
        // ..

Register the Route Middlewares in app/Http/Kernel.php:

    protected $routeMiddleware = [
        // ..
        'browser.allow' => \Spinen\BrowserFilter\Route\AllowFilter::class,
        'browser.block' => \Spinen\BrowserFilter\Route\BlockFilter::class,

Build a page with a named route to redirect blocked browsers to:

    // This is only a simple example.  You would probably want to route to a controller with a view.
    Route::get('incompatible_browser', ['as' => 'incompatible_browser', 'uses' => function() {
        return "You are using a blocked browser.";
    }]);

Configure middleware options

Publish the package config file to config/browserfilter.php:

$ php artisan vendor:publish --provider="Spinen\BrowserFilter\FilterServiceProvider"

This file is fully documented, so please read it to know how to configure the middleware. There are 4 top level items that you can configure...

1. type - The type of filtering strategy to apply to the stack filter
2. rules - The array of devices/browsers/versions to allow or block for ALL http requests
3. route - The name of the route to redirect the user to if they are using a blocked client
4. timeout - The length of time to cache the client data, where "0" disables the cache

Using the Route middleware

The route middleware uses the same configuration file as the stack middleware, but ignores the rules.

The rules are passed in after the ':' behind the route filter that you wish to use...

    Route::get('tablet_page', [
        'middleware' => 'browser.allow:Tablet',
        'uses'       => function () {
            return "Special page that is only accessible to tablets";
        }
    ]);

or

    Route::get('ie_is_blocked_page', [
        'middleware' => 'browser.block:Other/Ie',
        'uses'       => function () {
            return "Special page that is only accessible to non IE browsers on Desktops";
        }
    ]);

The format of the filter is Device/Browser/operatorVersion|operatorVersion2;Device/Browser2/operatorVersion, so the following rule:

    $rule = [
        'Mobile' => '*',
        'Other' => [
            'Ie' => [
                '<' => '10',
                '>' => '13',
            ],
        ],
        'Tablet' => '*',
    ]

would be written as: Mobile;Other/Ie/<10|>13;Tablet.
