How do you handle API versioning in Laravel?
1. Use URL Path Versioning with Middleware (Optional for Header-based Versioning)
Define different API versions in routes/api.php
using route prefixes. You can also create a middleware to handle versioning dynamically based on headers or request parameters.
Define API Versions in Routes:
In routes/api.php
, define routes for different API versions:
Example
<?php
// Version 1
Route::prefix('v1')->group(function () {
Route::get('/users', [UserV1Controller::class, 'index']);
Route::post('/users', [UserV1Controller::class, 'store']);
});
// Version 2
Route::prefix('v2')->group(function () {
Route::get('/users', [UserV2Controller::class, 'index']);
Route::post('/users', [UserV2Controller::class, 'store']);
});
?>
Middleware for Header-based Versioning:
Create a middleware to check for API versioning using request headers.
Example
php artisan make:middleware ApiVersionMiddleware
In app/Http/Middleware/ApiVersionMiddleware.php
:
Example
<?php
public function handle($request, Closure $next)
{
$version = $request->header('API-Version', 'v1'); // Default to v1 if not provided
$request->attributes->set('api_version', $version);
return $next($request);
}
?>
Register the middleware in app/Http/Kernel.php
:
Example
<?php
protected $routeMiddleware = [
'api.version' => \App\Http\Middleware\ApiVersionMiddleware::class,
];
?>
Use Middleware in Routes:
Example
<?php
Route::middleware('api.version')->group(function () {
Route::get('/users', [UserController::class, 'index']);
});
?>
2. Controller Logic Based on Version
Inside your controller, handle different versions using the version information from the request.
Example
<?php
public function index(Request $request)
{
$version = $request->get('api_version');
if ($version === 'v1') {
return UserV1Resource::collection(User::all());
}
return UserV2Resource::collection(UserV2::all());
}
?>
