How to Create URL Shortener using Laravel?

Hello Laravel Friends,

This Laravel tutorial illustrates How to Create URL Shortener using Laravel.

In the vast landscape of the internet, long and cumbersome URLs can be inconvenient and aesthetically unpleasing. Hence, the need for concise and user-friendly URLs is ever-growing. Link shortening is a popular technique that not only makes URLs more aesthetically pleasing but also enhances user experience.

Laravel, a powerful PHP web application framework, provides an ideal environment for implementing link shortening seamlessly. In this step-by-step guide, we’ll look into how to set up a basic link shortening functionality using Laravel, complete with practical examples.

Steps to Create URL Shortner in Laravel:

Step 1: Setting Up Your Laravel Project

If you haven’t already, install Laravel using Composer:

composer create-project --prefer-dist laravel/laravel link-shortener

Navigate to your project directory:

cd link-shortener

Step 2: Creating the Link Model and Migration

Generate a model and migration for links:

php artisan make:model Link -m

Edit the migration file to define the structure of the ‘links’ table:

Path – database/migrations/YYYY_MM_DD_create_links_table.php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateLinksTable extends Migration
{
    public function up()
    {
        Schema::create('links', function (Blueprint $table) {
            $table->id();
            $table->string('original_url');
            $table->string('short_url')->unique();
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('links');
    }
}

Run the migration to create the ‘links’ table:

php artisan migrate

Step 3: Implementing Link Shortening Logic

Install the ‘hashids’ package for generating unique, reversible hashes:

composer require vinkla/hashids

Update the Link model to include link shortening logic:

Path – app/Models/Link.php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Vinkla\Hashids\Facades\Hashids;

class Link extends Model
{
    use HasFactory;

    protected $fillable = ['original_url', 'short_url'];

    public static function shortenUrl($originalUrl)
    {
        $link = self::create(['original_url' => $originalUrl]);
        $link->short_url = Hashids::encode($link->id);
        $link->save();

        return $link;
    }

    public static function getOriginalUrl($shortUrl)
    {
        $linkId = Hashids::decode($shortUrl);
        $link = self::find($linkId);

        return $link ? $link->original_url : null;
    }
}

Step 4: Creating Routes and Controllers

Generate a controller for link operations:

php artisan make:controller LinkController

Add below code in controller file

Path – app/Http/Controllers/LinkController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Link;

class LinkController extends Controller
{
    public function create()
    {
        return view('create-link');
    }

    public function store(Request $request)
    {
        $request->validate(['url' => 'required|url']);

        $originalUrl = $request->input('url');
        $link = Link::shortenUrl($originalUrl);

        return redirect()->route('link.show', $link->short_url);
    }

    public function show($shortUrl)
    {
        $originalUrl = Link::getOriginalUrl($shortUrl);

        if (!$originalUrl) {
            abort(404);
        }

        return redirect($originalUrl);
    }
}

Define the routes in routes/web.php:

Path – routes/web.php

use App\Http\Controllers\LinkController;

Route::get('/', [LinkController::class, 'create']);
Route::post('/store', [LinkController::class, 'store'])->name('link.store');
Route::get('/{shortUrl}', [LinkController::class, 'show'])->name('link.show');

Step 5: Creating Views

Create a view for link creation:

Path – resources/views/create-link.blade.php

<!-- resources/views/create-link.blade.php -->

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Link Shortener</title>
</head>
<body>
    <h1>Link Shortener</h1>

    <form action="{{ route('link.store') }}" method="post">
        @csrf
        <label for="url">Enter URL:</label>
        <input type="text" name="url" id="url" required>
        <button type="submit">Shorten URL</button>
    </form>
</body>
</html>

Step 6: Deployment and Testing

Deploy your Laravel application and test the link shortening functionality.

Visit http://localhost:8000 in your browser, enter a URL in the form, and submit it. You should be redirected to a shortened URL, and visiting that URL should redirect you to the original link.
