How to create REST API in Laravel 9

Make REST API in LARAVEL 9

Today I am going to explain how you can make REST API in Laravel 9. In this video i am going to explain about CRUD Operation using REST API.

Laravel 9 Installation.

After Installing Laravel 9 we will open the code in Editor.

Step - 1

Create a Model Post with migration.

php artisan make:model Post -m

Next Update The Migration file at database/migrations folder.

<?php

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

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->longText('description');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
};

Next update the Model fillable property in app/models/Post.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    protected $fillable = ['title', 'description'];
}

Step - 2

Now Generate controller by running command

php artisan make:controller Api\\PostController --model=Post

this command will generate the file in app/Http/Controllers/Api/PostController.php

Open the file and update the code below.

<?php

namespace App\Http\Controllers\Api;

use App\Http\Controllers\Controller;
use App\Http\Requests\StorePostRequest;
use App\Models\Post;
use Illuminate\Http\Request;

class PostController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $posts = Post::all();

        return response()->json([
            'status' => true,
            'posts' => $posts
        ]);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(StorePostRequest $request)
    {
        $post = Post::create($request->all());

        return response()->json([
            'status' => true,
            'message' => "Post Created successfully!",
            'post' => $post
        ], 200);
    }

    /**
     * Display the specified resource.
     *
     * @param  \App\Models\Post  $post
     * @return \Illuminate\Http\Response
     */
    public function show(Post $post)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\Models\Post  $post
     * @return \Illuminate\Http\Response
     */
    public function edit(Post $post)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Models\Post  $post
     * @return \Illuminate\Http\Response
     */
    public function update(StorePostRequest $request, Post $post)
    {
        $post->update($request->all());

        return response()->json([
            'status' => true,
            'message' => "Post Updated successfully!",
            'post' => $post
        ], 200);
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Models\Post  $post
     * @return \Illuminate\Http\Response
     */
    public function destroy(Post $post)
    {
        $post->delete();

        return response()->json([
            'status' => true,
            'message' => "Post Deleted successfully!",
        ], 200);
    }
}

Step - 3

Now Let's create the request to validate the data by running command below.

php artisan make:request StorePostRequest

Now open file from app/Http/Requests/StorePostRequest.php and update the code below.

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StorePostRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            "title" => "required|max:70",
            "description" => "required"
        ];
    }
}

Step - 4

Now create the API routes in routes/api.php

<?php

use App\Http\Controllers\Api\PostController;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;


Route::apiResource('posts', PostController::class);
