I think I fixed it, however Debugbar still says it's hitting /dashboard before /characters/creator.

For people coming here in the future, I had to add:

return Inertia::render('game/character/Create'); 

Then make the vue, add some content to it, then run npm build

I've updated my Providers\FortifyServiceProvider.php to:

<?php

namespace App\Providers;

use App\Actions\Fortify\CreateNewUser;
use App\Actions\Fortify\ResetUserPassword;
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Str;
use Inertia\Inertia;
use Laravel\Fortify\Contracts\LoginResponse;
use Laravel\Fortify\Features;
use Laravel\Fortify\Fortify;

class FortifyServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        $this->app->instance(LoginResponse::class, new class implements LoginResponse {
            public function toResponse($request)
            {
                $user = $request->user();

                if ($user && $user->characters()->count() > 0) {
                    return redirect('characters');
                }

                return redirect('characters/creator');
            }
        });
    }
...

However it still isn't working

edit: I've made some progress, now I get a modal popup that says "App\Http\Responses\LoginResponse"

My code: App\Http\Responses:

<?php

namespace App\Http\Responses;

use Laravel\Fortify\Contracts\LoginResponse as LoginResponseContract;

class LoginResponse implements LoginResponseContract
{
    /**
     * @param  $request
     * @return mixed
     */
    public function toResponse($request)
    {
        $user = auth()->user();

        if ($user && $user->characters()->count() > 0) {
            return redirect()->intended('/characters');
        }

        return redirect()->intended('/characters/creator');
    }
}

FortifyServiceProvider:

    public function register(): void
    {
        // https://laravel-news.com/override-login-redirects-in-jetstream-fortify
        $this->app->instance(LoginResponseContract::class, LoginResponse::class);
        $this->app->instance(TwoFactorLoginResponse::class, LoginResponse::class); // singleton
    }

edit 2: After some research, I figured out it IS redirecting to where I want, but it re-redirects to /dashboard after that?

I updated my answer since I realized you're using Fortify. Check the edit at the end.

I don't have any auth controllers, in previous versions they were in Controllers\Auth I believe, but now I don't have any. How do I publish them?

I saw that in another thread while trying to solve things, however it never seems to work for me. What am I doing wrong? All it does is redirect me to /dashboard

<?php

use App\Http\Middleware\HandleAppearance;
use App\Http\Middleware\HandleInertiaRequests;
use Binafy\LaravelUserMonitoring\Middlewares\VisitMonitoringMiddleware;
use Illuminate\Auth\Middleware\RedirectIfAuthenticated;
use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;
use Illuminate\Http\Middleware\AddLinkHeadersForPreloadedAssets;
use Illuminate\Http\Request;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        commands: __DIR__.'/../routes/console.php',
        channels: __DIR__.'/../routes/channels.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware): void {
        $middleware->encryptCookies(except: ['appearance', 'sidebar_state']);
        $middleware->web(append: [
            HandleAppearance::class,
            HandleInertiaRequests::class,
            AddLinkHeadersForPreloadedAssets::class,
            VisitMonitoringMiddleware::class,
        ]);

        $middleware->redirectUsersTo(function(Request $request) {
            $user = auth()->user();

            if ($user && $user->characters()->count() > 0) {
                $route = 'game.characters';
            } else {
                $route = 'game.character_creator';
            }
            return route($route);
        });
    })
    ->withExceptions(function (Exceptions $exceptions): void {
        //
    })->create();

I'm struggling to figure out how to add logic to redirect users after they login to different pages depending on whether they have data in another table or not.

I need to be able to redirect users after they login using the Laravel built-in auth (Vue starter kit not using WorkOS). Where exactly is the logic that determines where the user is sent after logging in? Right now no matter what I do it redirects to /dashboard.

Thanks for the reply, would you suggest using Reverb + Redis? Am I wrong in thinking that Reverb keeps your code in memory and uses websockets instead of having the client make a request every time it needs updated data?

I'm starting a new personal project that will have multiple (As many as 10, possibly more) components that need to be updated every 250-500ms with updated data, all the data is pretty lightweight but with 10 components doing it I have to wonder if it'd be better to just use Laravel as an API and poll the server myself with something like axios.

For the record, my project is a PBBG (Persistent Browser-Based Game), and components will be for things like player health, stamina, currency, a list of players in the same area, etc..

"Shared Data" seems like it may be a solution since it looks like I can just write a middleware that sends the necessary data every update conditionally. Would using this be a good idea, or should I just roll my own solution?
