Creating RESTful APIs with Laravel 11 is straightforward and powerful. Laravel provides a simple and elegant way to build APIs quickly. In this tutorial, we’ll create a simple RESTful API for managing a collection of books.

Step 1: Setting Up Laravel

First, make sure you have Laravel installed. If not, you can install it via Composer:

composer create-project --prefer-dist laravel/laravel book-api

Step 2: Database Configuration

Let’s set up a database. Create a database named book_api and configure your .env file accordingly:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=book_api
DB_USERNAME=root
DB_PASSWORD=

Step 3: Create a Model and Migration

We’ll create a Book model and its corresponding migration to store our books.

php artisan make:model Book -m

In the migration file, define the schema for the books table:

public function up()
{
    Schema::create('books', function (Blueprint $table) {
        $table->id();
        $table->string('title');
        $table->string('author');
        $table->timestamps();
    });
}

Run the migration to create the books table:

php artisan migrate

Step 4: Create a Controller

Generate a controller named BookController:

php artisan make:controller BookController --api

Step 5: Define Routes

Define routes in routes/api.php:

use App\Http\Controllers\BookController;

Route::apiResource('/books', BookController::class);

Step 6: Implement Controller Methods

In BookController.php, implement the CRUD methods:

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

public function index()
{
    return Book::all();
}

public function store(Request $request)
{
    return Book::create($request->all());
}

public function show(Book $book)
{
    return $book;
}

public function update(Request $request, Book $book)
{
    $book->update($request->all());
    return $book;
}

public function destroy(Book $book)
{
    $book->delete();
    return response()->json(null, 204);
}

Step 7: Testing

You can now test your API using tools like Postman or curl.

Example requests:

  • GET /api/books – Retrieve all books
  • GET /api/books/{id} – Retrieve a specific book
  • POST /api/books – Create a new book
  • PUT /api/books/{id} – Update a book
  • DELETE /api/books/{id} – Delete a book

Conclusion

In this tutorial, we created a simple RESTful API for managing a collection of books using Laravel 11. This is just the beginning; Laravel provides a rich set of features to further develop and secure your APIs. Happy coding!
