API Versioning Strategies
API versioning lets you evolve your API without breaking existing clients. The most common approach is URL-based versioning (/api/v1/posts, /api/v2/posts). Each version can have different controllers, resources, and response formats.
URL-Based Versioning
// routes/api.php
Route::prefix('v1')->group(function () {
Route::apiResource('posts', V1\PostController::class);
Route::apiResource('users', V1\UserController::class);
});
Route::prefix('v2')->group(function () {
Route::apiResource('posts', V2\PostController::class);
Route::apiResource('users', V2\UserController::class);
});
// Controller organization:
// app/Http/Controllers/Api/V1/PostController.php
// app/Http/Controllers/Api/V2/PostController.php
// Resource organization:
// app/Http/Resources/V1/PostResource.php
// app/Http/Resources/V2/PostResource.php
// V2 can return different fields, include new relationships,
// or change response structure without affecting V1 clientsTip
Tip
Practice API Versioning Strategies in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
REST is the standard for modern web APIs

Common Mistake
Warning
A common mistake with API Versioning Strategies is skipping edge case testing — empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready laravel code.
