Question - check if request comes from Intertiajs components or API

[qwasyx0]

am wondering if there is a way to check on the backend (Laravel) if the request (for example GET /posts) comes from an Inertia frontend or from other source (like Postman API).

For now it seems if I wanted to make a public API for shared routes (like CRUD of Posts model), I would have to make separate routes, because the controller returns a server-side rendered Vuejs component.

Is there a way to do something like this:

public function index()
{
    $this->authorize('viewAny', Post::class);

    if(request()->isInertiaRequest()) {      //<- check if the request is API or Vuejs Inertia frontend
        return inertia('Posts/Index', [
            'posts' => PostResource::collection($this->postService->index()),
        ]);
    }
    return PostResource::collection($this->postService->index());
}

I feel like writing separate API and Inertia routes would go against DRY, as the returned data would be the same resource.

I'm not sure if this is documented, but you can use the inertia helper on the request: request()->inertia() It basically just checks if the request contains the X-Inertia header.

See: https://github.com/inertiajs/inertia-laravel/blob/master/src/ServiceProvider.php#L75-L77

@qwasyx0 you could tweak it like this just like @rojtjo mentioned

public function index()
{
    $this->authorize('viewAny', Post::class);

    if(! $request->inertia() && $request->expectsJson())  {  
         return PostResource::collection($this->postService->index());
    }

   return inertia('Posts/Index', [
            'posts' => PostResource::collection($this->postService->index()),
   ]);

}
