Laravel: How do you pass data to a blade.php?

Question

I am having difficulty in understanding how to pass data to a .blade. I want to pass the users' username ($user) to a dashboard component. Here's a few things I've tried:

return view('livewire.dashboard', ['user'=>'$user']);
return view('livewire.dashboard', compact('$user'));
return view('livewire.dashboard'->with('user',$user));

But then I realized that the class I was trying to pass the user info from didn't know what the user variable is. Here is the class (Dashboard.php):

<?php

namespace App\Http\Livewire;

use Illuminate\Contracts\View\View;
use Illuminate\Contracts\View\Factory;
use Illuminate\Contracts\Container\BindingResolutionException;
use Livewire\Component;

class Dashboard extends Component
{
    /**
     * @return View|Factory
     * @throws BindingResolutionException
     */
    public function render()
    {
        return view('livewire.dashboard');
    }
}

And here is my web.php file:

use App\Http\Livewire\Dashboard;
use App\Http\Livewire\User;

    // Dashboard
    Route::get('/', Dashboard::class)->name('dashboard');
    // I have also tried something like 'Route get user' here, also didn't work

     // User routes
    Route::prefix('/users')->group(function () {
        Route::get('/', User\Index::class)->name('users.index');
        Route::get('/create', User\Create::class)->name('users.create');
        Route::get('/{user}', User\Edit::class)->name('users.edit');
    });

I'm having difficulty understanding how components/classes/blade tamplates communicate with each other. How can I pass the username of the person currently logged in to my dashboard.blade.php file? It looks like this:

    @isset($user)
    Hallo {{ $user->name }},
    @endisset
</div>
<div>Willkommen im Formular-Editor!</div>
<div>Neue Formulare kannst du über den Tab "Editor" oben in der Leiste anlegen. Hier kannst Du auch bestehende Formulare bearbeiten.</div>  

An explanation as well as a solution would be appreciated, as I really don't understand how Laravel works. Thank you

Answer 1

You can pass them

<livewire:show-post :user="$user">

In Laravel Way

public function render()
{
    return view('livewire.dashboard', ['user' => auth()->user()]);
}

Apart from all

Laravel is a Well designed Framework. So passing the logged-in users here and there(fetch in the controller and pass to view with $user), you can directly access using the auth() helper.

In view

auth()->id();
auth()->user();
