Hello, world!

Run Command

php artisan install:api // it will create api file in routes folder

Now make model with migration and controller

php artisan make:model Post -mc --api

now in migration folder

$table→string('title');
$table→string('body');

and in model

$protected fillable=[
‘title’,
‘body’
];

Now in controller

$post=POST::get();
return response()→json([
‘message’=>'List of Pages',
‘posts’=>$post
],200);

now

php artisan migrate

Route::get('v1/post',[PostController::class,'index']);

Now if i want to store post

 public function store(Request $request)
{
$post=new POST;
$post→title=$request→title;
$post→content=$request→content;
$post→save();
}
return response()→json([
‘message’=>'New Post Created',
‘posts’=>$post
],200);

When you are using put you need to put method in form data in your request from postman

now with validation

We can do validation by inside the controller or making request

First by making request

php artisan make:request StorePostRequest

now inside app→http→request→your request file

First of all make authorize true in authorize function return true, then we can use it

now inside the rules function write your validation

return [
‘title’=>required | string,
‘content’=>required|string
]

now in your controller

use App\Http\Requests\StorePostRequest;

public function store (StorePostRequest $request)
{

}

in header insert accept key becuase you told server we need response in JSOn not in HTML then our validations will start working

now mention fillable field in model then in controller you can also update data like below you don't need to put extra things in your request

public function store (StorePostRequest $request)
{
//if we want to insert data
$post=POST::create($request-validated());
$post->updated($request->validated());
}

Now we can refactor our response because we are using the same code to send again and again and its actually cause code duplication

Note we are going to use abstract class and we can not make object of abstract class

now make a controller

php artisan make:controller ApiResponseController

now in your main controller like POSSTController

class PostController extends ApiController

Now in your api controller

public function successResponse($data, $message='success',$status=200) // These values are default if function is not get values then these default values will be used
{
return response()→json([
‘message’=>$message,
‘data’=>$data
],$status);
}

now in your main post controller

return $this→SuccessResponse($post);

now for error in controller class we define another function

public function errorResponse($data, $message='Error',$status=404) // These values are default if function is not get values then these default values will be used
{
return response()→json([
‘message’=>$message,
‘data’=>$data
],$status);
}

now in main controller pot controller

if(!$post)
{
return $this→errorResponse('Post Not Found');
}
else
{
return $this→SuccessResponse($post);
}

we can add prefix also like below

and if we want to get rid of this chunky code we can use api resource while we are making controller

make controller like below

php artisan make:model POSt -mc --api

you can check route list in command line

php artisan route:list
