Laravel Reverb: Four "Live" Practical Examples

There are many customer support chat solutions, but sometimes you need something simple. For that, we can use Reverb and create a chat around it:

On the admin side, the administrator user will be able to see the chat requests and reply to them:

With this solution, we don't need to use any third-party free/paid software. We also have complete control over how it works/looks of what happens. Finally, all the data stays on our servers.

Project Overview

Our demo project contains two critical parts in the application:

On the user side - we have a chatbox that will be used to send messages to the support team:

Chatbox has this code inside:

Note: Repository is linked at the end of the tutorial.

</script>

On the support side (admin), we have a list of all user-created chat rooms. From there, we can go inside the chat room and see all the messages that were sent:

We are simply using a controller and a table to display all the chat rooms:

app/Http/Controllers/CustomerChatsController.php

// ...
 
public function index()
{
    $chatRooms = ChatRoom::query()
        ->with(['user'])
        ->withCount('chatMessages')
        ->orderBy('updated_at', 'desc')
        ->paginate(15);
 
    return view('chatRooms.index', compact('chatRooms'));
}
 
// ...

resources/views/chatRooms/index.blade.php

{{-- ... --}}
 
<table class="w-full">
    <thead>
    <tr>
        <th class="border px-4 py-2">ID</th>
        <th class="border px-4 py-2">User Name</th>

    <tbody>
    @foreach ($chatRooms as $chatRoom)
        <tr>
            <td class="border px-4 py-2">{{ $chatRoom->identifier }}</td>
            <td class="border px-4 py-2">{{ $chatRoom->user->name }}</td>
            <td class="border px-4 py-2">{{ $chatRoom->chat_messages_count }}</td>
            <td class="border px-4 py-2">{{ $chatRoom->updated_at }}</td>
