laravel - Livewire 2.2: Undefined variable slot in app.blade.php

Solution:

Since you're using the @section directive (where you @extend a layout, and use sections), and not the component $slot approach (see https://laravel.com/docs/8.x/blade#slots), you should be using @yield instead of echoing the "special" $slot variable.

Alternatively you could go with the slots-approach, but you would generally choose one or the other. Going with that approach means a different structure to your blade files, and there's nothing wrong with either way -- just be consistent about which one you choose.

To continue using sections and extending layouts, simply replace {{ $slot }} with @yield('content'), like

<div class="container">
    @yield('content')
</div>

Solution:

If you still want to use slot please create component php artisan make:component Layouts/Login and on render function in Livewire controller Http/Livewire/... add layout

public function render()
    {
        return view('livewire.pages.login')
            ->layout('components.layouts.login');
    }

Solution:

instead of

@extends('layouts.app')

I found that laravel 10 uses x-app-layout

<x-app-layout>

</x-app-layout>
