API Resources: With or Without "data"?

If you use Eloquent API Resources to return data, they will be automatically wrapped in 'data'. If you want to remove it, add JsonResource::withoutWrapping(); in app/Providers/AppServiceProvider.php.

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        JsonResource::withoutWrapping();
    }
}

API Return "Everything went ok"

If you have API endpoint which performs some operations but has no response, so you wanna return just "everything went ok", you may return 204 status code "No content". In Laravel, it's easy: return response()->noContent();.

public function reorder(Request $request)
{
    foreach ($request->input('rows', []) as $row) {
        Country::find($row['id'])->update(['position' => $row['position']]);
    }

    return response()->noContent();
}

Avoid N+1 queries in API resources

You can avoid N+1 queries in API resources by using the whenLoaded() method.
This will only append the department if it’s already loaded in the Employee model.
Without whenLoaded() there is always a query for the department

class EmplyeeResource extends JsonResource
{
    public function toArray($request): array
    {
        return [
            'id' => $this->uuid,
            'fullName' => $this->full_name,
            'email' => $this->email,
            'jobTitle' => $this->job_title,
            'department' => DepartmentResource::make($this->whenLoaded('department')),
        ];
    }
}

Get Bearer Token from Authorization header

The bearerToken() function is very handy when you are working with apis & want to access the token from Authorization header.

// Don't parse API headers manually like this:
$tokenWithBearer = $request->header('Authorization');
$token = substr($tokenWithBearer, 7);

//Do this instead:
$token = $request->bearerToken();

Sorting Your API Results

Single-column API sorting, with direction control

// Handles /dogs?sort=name and /dogs?sort=-name
Route::get('dogs', function (Request $request) {
    // Get the sort query parameter (or fall back to default sort "name")
    $sortColumn = $request->input('sort', 'name');

    // Set the sort direction based on whether the key starts with -
    // using Laravel's Str::startsWith() helper function
    $sortDirection = Str::startsWith($sortColumn, '-') ? 'desc' : 'asc';
    $sortColumn = ltrim($sortColumn, '-');

    return Dog::orderBy($sortColumn, $sortDirection)
        ->paginate(20);
});

we do the same for multiple columns (e.g., ?sort=name,-weight)

// Handles ?sort=name,-weight
Route::get('dogs', function (Request $request) {
    // Grab the query parameter and turn it into an array exploded by ,
    $sorts = explode(',', $request->input('sort', ''));

    // Create a query
    $query = Dog::query();

    // Add the sorts one by one
    foreach ($sorts as $sortColumn) {
        $sortDirection = Str::startsWith($sortColumn, '-') ? 'desc' : 'asc';
        $sortColumn = ltrim($sortColumn, '-');

        $query->orderBy($sortColumn, $sortDirection);
    }

    // Return
    return $query->paginate(20);
});
