Simple Laravel REST API


1) Create the user model in models/UserModel.php 

php artisan make:model User

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;

class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;

/**
* The attributes that are mass assignable.
*
* @var array<int, string>
*/
protected $fillable = [
'name',
'email',
'password',
];

/**
* The attributes that should be hidden for serialization.
*
* @var array<int, string>
*/
protected $hidden = [
'password',
'remember_token',
];

/**
* The attributes that should be cast.
*
* @var array<string, string>
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
}

 

2) 

create validation for the update requests:  php artisan make:request UserUpdateRequest

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class UserUpdateRequest 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 [
'name'=>'required',
'email'=>'required|email',
// 'password'=>''
];
}
}


 and for the post request:

php artisan make:request UserPostRequest

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class UserPostRequest 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 [
'name'=>'required',
'email'=>'required|email',
'password'=>'required'
];
}
}


 

 

create user controller based on the user model: php artisan make:controller UserController --model=User --resource

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Http\Requests\UserPostRequest;
use App\Http\Requests\UserUpdateRequest;
use App\Http\Resources\UserCollection;
use App\Http\Resources\UserResource;
use App\Models\User;
use Illuminate\Support\Facades\Hash;

class UserController extends Controller
{
public function index()
{
return new UserCollection(User::paginate(5));
}

public function store(UserPostRequest $request)
{
$userData = $request->validated();
$userData['password'] = Hash::make($userData['password']);
$userData['email_verified_at'] = now();

$user = User::forceCreate($userData);
return new UserResource($user);
}

public function show(User $user) //route model binding
{
return new UserResource($user);
}

public function update(User $user, UserUpdateRequest $request)
{
$user->update($request->validated());
}

public function destroy(User $user)
{
$user->delete();
return response()->noContent();
}
}



3) create resources/UserCollection:  php artisan make:resource UserCollection

to return user collection and user resource, when required by the user controller.

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\ResourceCollection;

class UserCollection extends ResourceCollection
{
/**
* Transform the resource collection into an array.
*
* @param \Illuminate\Http\Request $request
* @return array|\Illuminate\Contracts\Support\Arrayable|\JsonSerializable
*/

public function toArray($request)
{
return
[
'data'=>$this->collection,
'total_count'=> $this->total()
];
}
}

 

create UserResource: //expose which fields to be returned in the json response.

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;

class UserResource extends JsonResource
{
/**
* Transform the resource into an array.
*
* @param \Illuminate\Http\Request $request
* @return array|\Illuminate\Contracts\Support\Arrayable|\JsonSerializable
*/
public function toArray($request)
{
return [
'id' => $this->id,
'name' => $this->name,
'email' => $this->email,
];
}
}

 

4) enable the requests to be performed, and add validation rules when posting and updating information, inside Requests/UserPostRequest.php

php artisan make:request UserPostRequest

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class UserPostRequest 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 [
'name'=>'required',
'email'=>'required|email',
'password'=>'required'
];
}
}

for updating info:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class UserUpdateRequest 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 [
'name'=>'required',
'email'=>'required|email',
];
}
}

 

6) add routes/api.php in order to redirect /users to the index() method of the UserController.
<?php

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

use App\Http\Resources\UserCollection;
use App\Models\User;
use App\Http\Controllers\UserController;

Route::apiResource('users', UserController::class);

Cheers!
