Creating First CRUD

Let's start by creating our base API application with our first CRUD - Categories:

Creating a new Laravel Project

Let's start by creating a new Laravel project. Open your terminal and run the following command:

laravel new laravel-api-flutter-api-code

Then we will select None as our Starter kit:

Creating our First Model and Migration

Let's create our first model and migration for our categories. Run the following command:

php artisan make:model Category -m

Then we fill in our fields:

Migration

Schema::create('categories', function (Blueprint $table) {
    $table->id();
    $table->foreignId('user_id')->nullable()->constrained();
    $table->string('name');
    $table->timestamps();
});

Then, we prepare our model:

app/Models/Category.php

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsTo;
 
class Category extends Model
{
    use HasFactory;
 
    protected $fillable = [
        'user_id',
        'name',
    ];
 
    public function user(): BelongsTo
    {
        return $this->belongsTo(User::class);
    }
}

Creating a Controller

Let's create our API Resource Controller for our categories. Run the following command:

php artisan make:controller Api/CategoryController --resource --api --model=Category

This will create a new controller with all the necessary methods for our CRUD:

app/Http/Controllers/Api/CategoryController.php

use App\Http\Controllers\Controller;
use App\Models\Category;
use Illuminate\Http\Request;
 
class CategoryController extends Controller
{
    /**
     * Display a listing of the resource.
     */
    public function index()
    {
        //
    }
 
    /**
     * Store a newly created resource in storage.
     */
    public function store(Request $request)
    {
        //
    }
 
    /**
     * Display the specified resource.
     */
    public function show(Category $category)
    {
        //
    }
 
    /**
     * Update the specified resource in storage.
     */
    public function update(Request $request, Category $category)
    {
        //
    }
 
    /**
     * Remove the specified resource from storage.
     */
    public function destroy(Category $category)
    {
        //
    }
}

Returning First API Response
