GitHub - ash-jc-allen/short-url: A Laravel package for creating shortened URLs for your web apps.

Overview

A Laravel package that can be used for adding shortened URLs to your existing web app.

Installation

Requirements

The package has been developed and tested to work with the following minimum requirements:

PHP 8.0
Laravel 8.0

Short URL requires either the BC Math or GMP PHP extensions in order to work.

Install the Package

You can install the package via Composer:

composer require ashallendesign/short-url

Publish the Config and Migrations

You can then publish the package's config file and database migrations by using the following command:

php artisan vendor:publish --provider="AshAllenDesign\ShortURL\Providers\ShortURLProvider"

Migrate the Database

This package contains two migrations that add two new tables to the database: short_urls and short_url_visits. To run these migrations, simply run the following command:

php artisan migrate

Usage

Building Shortened URLs

Quick Start

The quickest way to get started with creating a shortened URL is by using the snippet below. The ->make() method returns a ShortURL model that you can grab the shortened URL from.

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->make();
$shortURL = $shortURLObject->default_short_url;

Custom Keys

By default, the shortened URL that is generated will contain a random key. The key will be of the length that you define in the config files (defaults to 5 characters). Example: if a URL is https://webapp.com/short/abc123, the key is abc123.

You may wish to define a custom key yourself for that URL that is more meaningful than a randomly generated one. You can do this by using the ->urlKey() method. Example:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->urlKey('custom-key')->make();
$shortURL = $shortURLObject->default_short_url;

// Short URL: https://webapp.com/short/custom-key

Note: All of the URL keys are unique, so you cannot use a key that already exists in the database for another shortened URL.

Tracking Visitors

You may want to track some data about the visitors that have used the shortened URL. This can be useful for analytics. By default, tracking is enabled and all of the available tracking fields are also enabled. You can toggle the default options for the different parts of the tracking in the config file. Read further on in the Customisation section to see how to customise the default tracking behaviours.

Note: Even if the tracking options (such as track_ip_address) are enabled for a short URL, they won't be recorded unless the track_visits options is enabled. This can come in handy if you want to enable/disable tracking for a short URL without needing to individually set each option.

Enabling Tracking

If you want to override whether if tracking is enabled or not when creating a shortened URL, you can use the ->trackVisits() method. This method accepts a boolean but defaults to true if a parameter is not passed.

The example below shows how to enable tracking for the URL and override the config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->make();

The example below shows how to disable tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits(false)->make();

Tracking IP Address

If you want to override whether if IP address tracking is enabled or not when creating a shortened URL, you can use the ->trackIPAddress() method. This method accepts a boolean but defaults to true if a parameter is not passed.

The example below shows how to enable IP address tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackIPAddress()->make();

Tracking Browser & Browser Version

If you want to override whether if browser name and browser version tracking is enabled or not when creating a shortened URL, you can use the ->trackBrowser() and ->trackBrowserVersion() methods. This method accepts a boolean but defaults to true if a parameter is not passed.

The example below shows how to enable browser name tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackBrowser()->make();

The example below shows how to enable browser version tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackBrowserVersion()->make();

Tracking Operating System & Operating System Version

If you want to override whether if operating system name and operating system version tracking is enabled or not when creating a shortened URL, you can use the ->trackOperatingSystem() and ->trackOperatingSystemVersion() methods. These methods accept a boolean but default to true if a parameter is not passed.

The example below shows how to enable operating system name tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackOperatingSystem()->make();

The example below shows how to enable operating system version tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackOperatingSystemVersion()->make();

Tracking Device Type

If you want to override whether if device type tracking is enabled or not when creating a shortened URL, you can use the ->trackDeviceType() method. This method accepts a boolean but defaults to true if a parameter is not passed.

The example below shows how to enable device type tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackDeviceType()->make();

Tracking Referer URL

If you want to override whether if referer URL tracking is enabled or not when creating a shortened URL, you can use the ->trackRefererURL() method. This method accepts a boolean but defaults to true if a parameter is not passed.

The example below shows how to enable referer URL tracking for the URL and override the default config variable:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->trackVisits()->trackRefererURL()->make();

Custom Short URL Fields

There may be times when you want to add your own custom fields to the ShortURL model and store them in the database. For example, you might want to associate the short URL with a tenant, organisation, user, etc.

To do this you can use the beforeCreate method when building your short URL. This method accepts a closure that receives the AshAllenDesign\ShortURL\Models\ShortURL model instance before it's saved to your database.

The example below shows how to add a tenant_id field to the AshAllenDesign\ShortURL\Models\ShortURL model:

use AshAllenDesign\ShortURL\Models\ShortURL;
use AshAllenDesign\ShortURL\Facades\ShortURL as ShortUrlBuilder;

$tenantId = 123;

$shortURL = ShortUrlBuilder::destinationUrl($url)
    ->beforeCreate(function (ShortURL $model): void {
        $model->tenant_id = $tenantId;
    })
    ->make();

Please remember that to store custom fields in the database, you'll have to make sure those fields are added to the short_urls table. You can do this by creating a new migration that adds the fields to the table, or by updating the migrations that ship with this package.

Single Use

By default, all of the shortened URLs can be visited for as long as you leave them available. However, you may want to only allow access to a shortened URL once. Then any visitors who visit the URL after it has already been viewed will get a HTTP 404.

To create a single use shortened URL, you can use the ->singleUse() method.

The example below shows how to create a single use shortened URL:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')->singleUse()->make();

Enforce HTTPS

When building a shortened URL, you might want to enforce that the visitor is redirected to the HTTPS version of the destination URL. This can be particularly useful if you're allowing your web app users to create their own shortened URLS.

To enforce HTTPS, you can use the ->secure() method when building the shortened URL.

The example below shows how to create a secure shortened URL:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('http://destination.com')->secure()->make();

// Destination URL: https://destination.com

Forwarding Query Parameters

When building a short URL, you might want to forward the query parameters sent in the request to destination URL. By default, this functionality is disabled, but can be enabled by setting the forward_query_params config option to true.

Alternatively, you can also use the ->forwardQueryParams() method when building your shortened URL, as shown in the example below:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('http://destination.com?param1=test')->forwardQueryParams()->make();

Based on the example above, assuming that the original short URL's destination_url was https://destination.com, making a request to https://webapp.com/short/xxx?param1=abc&param2=def would redirect to https://destination.com?param1=test&param2=def

Redirect Status Code

By default, all short URLs are redirected with a 301 HTTP status code. But, this can be overridden when building the shortened URL using the ->redirectStatusCode() method.

The example below shows how to create a shortened URL with a redirect HTTP status code of 302:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('http://destination.com')->redirectStatusCode(302)->make();

Activation and Deactivation Times

By default, all short URLs that you create are active until you delete them. However, you may set activation and deactivation times for your URLs when you're creating them.

Doing this can be useful for marketing campaigns. For example, you may want to launch a new URL for a marketing campaign on a given date and then automatically deactivate that URL when the marketing campaign comes to an end.

The example below shows how to create a shortened URL that will be active from this time tomorrow onwards:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->activateAt(\Carbon\Carbon::now()->addDay())->make();

The example below shows how to create a shortened URL that will be active from this time tomorrow onwards and then is deactivated the day after:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->activateAt(\Carbon\Carbon::now()->addDay())
                          ->deactivateAt(\Carbon\Carbon::now()->addDays(2))
                          ->make();

Using a Custom Seed

By default, the package will use the ID of the last inserted short URL as the seed for generating a short URL's key. In some cases, you may want to use a custom seed instead. To do this, you can pass an integer to the generateKeyUsing method like so:

use AshAllenDesign\ShortURL\Classes\Builder;

$shortURLObject = app(Builder::class)->destinationUrl('https://destination.com')
   ->generateKeyUsing(12345)
   ->make();

Facade

If you prefer to use facades in Laravel, you can choose to use the provided ShortURL facade instead of instantiating the Builder class manually.

The example below shows an example of how you could use the facade to create a shortened URL:

<?php

namespace App\Http\Controllers;

use ShortURL;

class Controller
{
    public function index()
    {
        $shortURLObject = ShortURL::destinationUrl('https://destination.com')->make();
        ...
    }
}

Conditionals

The Builder class uses the Illuminate\Support\Traits\Conditionable trait, so you can use the when and unless methods when building your short URLs.

For example, let's take this block of code that uses if when building the short URL:

use AshAllenDesign\ShortURL\Classes\Builder;
 
$builder = app(Builder::class)->destinationUrl('https://destination.com');

if ($request->date('activation')) {
    $builder = $builder->activateAt($request->date('activation'));
};

$shortURLObject = $builder->make();

This could be rewritten using when like so:

use AshAllenDesign\ShortURL\Classes\Builder;
use Carbon\Carbon;

$shortURLObject = app(Builder::class)
   ->destinationUrl('https://destination.com')
   ->when(
       $request->date('activation'),
       function (Builder $builder, Carbon $activateDate): Builder  {
           return $builder->activateAt($activateDate);
       },
   )
   ->make();

Using the Shortened URLs

Default Route and Controller

By default, the shortened URLs that are created use the package's route and controller. The routes use the following structure: https://webapp.com/short/{urlKey}. This route uses the single-use controller that is found at \AshAllenDesign\ShortURL\Controllers\ShortURLController.

Custom Route

You may wish to use a different routing structure for your shortened URLs other than the default URLs that are created. For example, you might want to use https://webapp.com/s/{urlKey} or https://webapp.com/{urlKey}. You can customise this to suit the needs of your project.

To use the custom routing all you need to do is add a web route to your project that points to the ShortURLController and uses the {shortURLKey} field.

The example below shows how you could add a custom route to your web.php file to use the shortened URLs:

Route::get('/custom/{shortURLKey}', '\AshAllenDesign\ShortURL\Controllers\ShortURLController');

Note: If you use your own custom routing, you might want to disable the default route that the app provides. Details are provided for this in the Customisation section below.

Tracking

If tracking is enabled for a shortened URL, each time the link is visited, a new ShortURLVisit row in the database will be created. By default, the package is set to record the following fields of a visitor:

IP Address
Browser Name
Browser Version
Operating System Name
Operating System Version
Referer URL (the URL that the visitor originally came from)
Device Type (can be: desktop/mobile/tablet/robot)

Each of these fields can be toggled in the config files so that you only record the fields you need. Details on how to do this are provided for this in the Customisation section below.

Customisation

Customising the Default Route

Customising the Default URL

The package comes with a route that you can use for your short URLs. By default, this route uses your Laravel app's app.url config field to build the URL.

However, you might want to override this and use a different URL for your short URLs. For instance, you might want to use a different domain name for your short URLs.

To override the base URL, you can set the default_url config field. For example, to set the base URL to https://example.com, you can set the default_url in your config/short-url.php file like so:

'default_url' => 'https://example.com',

To use the your application's app.url config field, you can set the short_url.default_url field to null.

Customising the Prefix

The package comes with a route that you can use for your short URLs. By default, this route is /short/{shortURLKey}.

You might want to keep using this default route but change the /short/ prefix to something else. To do this, you can change the prefix field in the config.

For example, to change the default short URL to /s, you could change the config value like so:

'prefix' => 's',

Removing the Prefix

You may also remove the prefix from the default route completely. For example, if you want your short URL to be accessible via /{shortUrlKey}, then you can update the prefix config value to null like so:

'prefix' => null,

Defining Middleware

You may wish to run the default short URL through some middleware in your application. To do this, you can define the middleware that the route should use via the middleware config value.

For example, if you have a MyAwesomeMiddleware class, you could update your short-url config like so:

'middleware' => [
    MyAwesomeMiddleware::class,
],

You can also use this same approach to define middleware groups rather than individual middleware classes. For example, if you want your default short URL route to use the web middleware group, you could update your config like so:

'middleware' => [
    'web',
],

It's important to note that this middleware will only be automatically applied to the default short URL route that ships with the package. If you are defining your own route, you'll need to apply this middleware to your route yourself.

Disabling the Default Route

If you have added your own custom route to your project, you may want to block the default route that the package provides. You can do this by setting the following value in the config:

'disable_default_route' => true,

If the default route is disabled, any visitors who go to the /short/{shortURLKey} route will receive a HTTP 404.

You may want to manually prevent the route from being automatically registered and manually register it yourself in your own routes file. To do this you can add the following code to your routes file (e.g. web.php):

\AshAllenDesign\ShortURL\Facades\ShortURL::routes();

Default URL Key Length

When building a shortened URL, you have the option to define your own URL key or to randomly generate one. If one is randomly generated, the minimum length of it is determined from the config.

A minimum key length of 3 has been enforced for performance reasons.

For example, to create a shortened URL with a key length of 10 characters, you could set the following in the config:

'key_length' => 10,

By default, the shortened URLs that are created have a key length of 5.

Please be aware that the key length that you specify in the config is only a desirable length. It acts as a minimum length rather than a fixed length. For example, if the key_length is set to 3 in the config and there is a unique 3 character long key that hasn't been used yet, the key created will be 3 characters long. However, if all of the possible 3 character long keys are taken, a 4 character key will be created.

The Hashids library is used to assist with creating the URL keys.

Tracking Visits

By default, the package enables tracking of all the available fields on each URL built. However, this can be toggled in the config file.

Default Tracking

To disable tracking by default on all future short URLs that are generated, set the following in the config:

'tracking'   => [
        'default_enabled' => true,
        ...
]

Note: Disabling tracking by default won't disable tracking for any shortened URLs that already exist. It will only apply to all shortened URLs that are created after the config update.

Tracking Fields

You can toggle the default options for each of fields that can be tracked by changing them in the config. These options can then be overridden for each short URL at the point of creation, as shown in the Tracking Visitors section.

For example, the snippet below shows how we could record all of the fields apart from the IP address of the visitor:

'tracking'   => [
        ...
        'fields' => [
            'ip_address'               => false,
            'operating_system'         => true,
            'operating_system_version' => true,
            'browser'                  => true,
            'browser_version'          => true,
            'referer_url'              => true,
            'device_type'              => true,
        ],
    ],

Config Validation

By default, the values defined in the short-url.php config file are not validated. However, the library contains a validator that can be used to ensure that your values are safe to use. To enable the config validation, you can set the following option in the config:

'validate_config' => true,

Custom Database Connection

By default, Short URL will use your application's default database connection. But there may be times that you'd like to use a different connection. For example, you might be building a multi-tenant application that uses a separate connection for each tenant, and you may want to store the short URLs in a central database.

To do this, you can set the connection name using the connection config value in the config/short-url.php file like so:

'connection' => 'custom_database_connection_name',

Specifying the Key Generator

By default, Short URL uses the AshAllenDesign\ShortURL\Classes\KeyGenerator class to generate the keys for the short URL. However, you may want to use your own custom key generator class.

To do this, you can define the class to be used in the short-url.php config file like so:

'url_key_generator' => \AshAllenDesign\ShortURL\Classes\KeyGenerator::class,

You'll just need to ensure that your custom key generator class implements the AshAllenDesign\ShortURL\Interfaces\KeyGenerator interface.

Specifying the User Agent Parser

By default, Short URL uses whichbrowser/parser package to parse the user agent header of the visitor when tracking visits. However, you may want to use your own custom user agent parser.

To do this, you can define the class to be used in the short-url.php config file like so:

'user_agent_driver' => \AshAllenDesign\ShortURL\Classes\UserAgent\ParserPhpDriver::class,

You'll just need to ensure that your custom user agent parser class implements the AshAllenDesign\ShortURL\Interfaces\UserAgentDriver interface.

Specifying the Allowed URL Schemes

By default, Short URL will allow you to create a shortened URL for any URLs beginning with http:// or https://.

However, you may want to change this list of allowed URL schemes. For example, this may be to restrict the creation to only https:// URLs. Or, it may be to allow URLs to be created using other schemes such as mailto:// or even custom schemes for your own applications.

To change the list of allowed URL schemes, you can define the list using the allowed_url_schemes field in your short-url.php config file like so:

'allowed_url_schemes' => [
    'http://',
    'https://',
    'mailto://',
    'myapp://',
],

Helper Methods

Visits

The ShortURL model includes a relationship (that you can use just like any other Laravel model relation) for getting the visits for a shortened URL.

To get the visits using the relationship, use ->visits or ->visits(). The example snippet belows shows how:

$shortURL = \AshAllenDesign\ShortURL\Models\ShortURL::find(1);
$visits = $shortURL->visits;

Find by URL Key

To find the ShortURL model that corresponds to a given shortened URL key, you can use the ->findByKey() method.

For example, to find the ShortURL model of a shortened URL that has the key abc123, you could use the following:

$shortURL = \AshAllenDesign\ShortURL\Models\ShortURL::findByKey('abc123');

Find by Destination URL

To find the ShortURL models that redirect to a given destination URL, you can use the ->findByDestinationURL() method.

For example, to find all of the ShortURL models of shortened URLs that redirect to https://destination.com, you could use the following:

$shortURLs = \AshAllenDesign\ShortURL\Models\ShortURL::findByDestinationURL('https://destination.com');

Tracking Enabled

To check if tracking is enabled for a short URL, you can use the ->trackingEnabled() method. It will return true if tracking is enabled, and false if not.

The following example shows how to check if a short URL has tracking enabled:

$shortURL = \AshAllenDesign\ShortURL\Models\ShortURL::first();
$shortURL->trackingEnabled();

Tracked Fields

To check which fields are enabled for tracking for a short URL, you can use the ->trackingFields() method. It will return an array with the names of each field that is currently enabled for tracking.

Note: Even if the tracking options (such as track_ip_address) are enabled for a short URL and returned, they won't be recorded unless the track_visits options is enabled. This can come in handy if you want to enable/disable tracking for a short URL without needing to individually set each option.

The following example shows how to get an array of all tracking-enabled fields for a short URL:

$shortURL = \AshAllenDesign\ShortURL\Models\ShortURL::first();
$shortURL->trackingFields();

Model Factories

The package comes with model factories included for testing purposes which come in handy when generating polymorphic relationships. The ShortURL model factory also comes with extra states that you may use when necessary, such as deactivated and inactive:

use AshAllenDesign\ShortURL\Models\ShortURL;

$shortUrl = ShortURL::factory()->create();

// URL is deactivated
$deactivatedShortUrl = ShortURL::factory()->deactivated()->create();

// URL is neither activated nor deactivated
$inactiveShortURL = ShortURL::factory()->inactive()->create();

If you are using your own custom model factory, you can define the factories that the ShortURL and ShortURLVisit models should use by updating the factories config field:

'factories' => [
    \AshAllenDesign\ShortURL\Models\ShortURL::class => \AshAllenDesign\ShortURL\Models\Factories\ShortURLFactory::class,
    \AshAllenDesign\ShortURL\Models\ShortURLVisit::class => \AshAllenDesign\ShortURL\Models\Factories\ShortURLVisitFactory::class
],

Events

Short URL Visited

Each time a short URL is visited, the following event is fired that can be listened on:

AshAllenDesign\ShortURL\Events\ShortURLVisited

If you are redirecting users with a 301 HTTP status code, it's possible that this event will NOT be fired if a visitor has already visited this short URL before. This is due to the fact that most browsers will cache the intended destination URL as a 'permanent redirect' and won't actually visit the short URL first.

For better results, use the 302 HTTP status code as most browsers will treat the short URL as a 'temporary redirect'. This means that the short URL will be visited in the browser and the event will be dispatched as expected before redirecting to the destination URL.

Testing

To run the package's unit tests, run the following command:

vendor/bin/phpunit
