README

A lightweight and flexible Laravel package for generating and managing short URLs. This package simplifies the process of creating short links with customizable options, middleware, and bot protection.

Features

• 📏 Customizable token formats and lengths: Choose from mixed, numeric, or alphabetic tokens.
• 🛡 Bot protection: Optionally block requests from known bots.
• ⚡ Quick setup: Easily integrate into existing Laravel projects.
• 🔒 Token encryption: Secure your tokens with a custom encryption callback.
• 🎛 Middleware support: Add custom middleware to short URL routes.

Installation

Install the package via Composer:

composer require cndrsdrmn/short-url

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=short-url-config

The configuration file config/short-url.php will be published. It includes the following options:

return [
    /*
    |--------------------------------------------------------------------------
    | URL Prefix
    |--------------------------------------------------------------------------
    |
    | This value sets the prefix for the short URL routes. It will be used as the
    | base path for accessing the short URLs.
    |
    */
    'prefix' => '/s',

    /*
    |--------------------------------------------------------------------------
    | Allowed Schemas
    |--------------------------------------------------------------------------
    |
    | Specify the schema can be allowed for generated token.
    |
    */
    'allowed_schemas' => [
        'http',
        'https'
    ],

    /*
    |--------------------------------------------------------------------------
    | Database Connection
    |--------------------------------------------------------------------------
    |
    | Specify the database connection to be used for storing short URLs. If null,
    | the default connection defined in the database configuration will be used.
    |
    */
    'connection' => null,

    /*
    |--------------------------------------------------------------------------
    | Middleware
    |--------------------------------------------------------------------------
    |
    | Define the middleware to apply to the short URL routes. By default, the routes
    | are throttled to prevent abuse. You can modify or extend the middleware stack
    | as needed.
    |
    */
    'middleware' => [
        'throttle:100,1',
    ],

    /*
    |--------------------------------------------------------------------------
    | Token Format
    |--------------------------------------------------------------------------
    |
    | Specify the format used to generate tokens for short URLs. Supported values:
    | - "bothify": Mix of letters and numbers (e.g., `A1b2C`)
    | - "numerify": Numbers only (e.g., `12345`)
    | - "lexify": Letters only (e.g., `ABCDE`)
    |
    */
    'token_format' => 'bothify',

    /*
    |--------------------------------------------------------------------------
    | Token Length
    |--------------------------------------------------------------------------
    |
    | Define the length of the token generated for the short URLs. The token's
    | length determines how many characters will be included in the generated URL.
    |
    */
    'token_length' => 5,

    /*
    |--------------------------------------------------------------------------
    | Block Bots
    |--------------------------------------------------------------------------
    |
    | If enabled, requests from known bots will be blocked from accessing the
    | short URLs. This is useful for preventing automated access and ensuring
    | accurate analytics.
    |
    */
    'should_block_bots' => true,
];

Usage

Basic Usage

Shorten a URL

You can easily generate a short URL with the ShortUrl facade:

use Cndrsdrmn\ShortUrl\Facades\ShortUrl;

$shortUrl = ShortUrl::shorten('https://example.com');
echo $shortUrl; // Outputs the short URL

Advanced Usage

Customizing the Builder

Customize your short URL with the make method:

use Cndrsdrmn\ShortUrl\Facades\ShortUrl;

$builder = ShortUrl::make('https://example.com', [
    'is_single_use' => true,
]);

$shortUrl = $builder->create();
echo $shortUrl->accessLink;

Setting Custom Headers and Queries

$builder = ShortUrl::make('https://example.com')
    ->headers(['X-Custom-Header' => 'value'])
    ->queries(['utm_source' => 'newsletter']);

$shortUrl = $builder->create();
echo $shortUrl->accessLink;

Routes

By default, the package automatically registers a route for handling short URL redirections. If you want to customize the routing:

1. Disable route registration on boot in App\Providers\AppServiceProvider:

   ShortUrl::ignoreRoutes();

2. Define your own route in routes/web.php:

   use App\Http\Controllers\RedirectController;
   
   Route::get('/s/{token}', [RedirectController::class, 'handle']);

Security

Encrypt Tokens

Set a custom encryption callback to secure your tokens:

ShortUrl::encryptTokenUsing(function ($token) {
    return encrypt($token);
});

Testing

Run the tests with PHPUnit:

php artisan test
