Types of Laravel Pusher Channels

Pusher provides four types of channels for developers to use in their real-time applications:

Public Channels: These channels are open to everyone; any user can subscribe to them without any authentication. Public channels are suitable for broadcasting events that everyone can see.
Private Channels: These channels are only accessible to authenticated users. You can use private channels to send sensitive information only specific users should see.
Presence Channels: These channels are similar to private channels but also provide information about who is currently subscribed to the channel. Presence channels are useful for building real-time chat applications, online collaboration tools, and multiplayer games.
Encrypted Channels: These channels provide end-to-end encryption for messages sent between clients and servers. Encrypted channels are useful for applications that deal with sensitive data or require high security.

Developers can choose the appropriate type of channel based on their application’s use case and security requirements. Pusher’s channel types offer a range of options to suit various needs and enable developers to build real-time applications quickly and easily.

2. Click on the “Create new app” button.
3. Fill out the form with your app’s name, description, and the technology you’ll be using (e.g., JavaScript, React, iOS, etc.).

Example Of Chat App with Laravel Pusher and JQuery

In this Laravel Pusher tutorial, we will see how to create a real-time chat application using Pusher in Laravel.

Step 1: Install Package

composer require pusher/pusher-php-server

Configure app credentials to your .env file

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=
PUSHER_APP_CLUSTER=
Don’t forget to clear cache : php artisan config:clear

Step 2: Create Route

Route::post(‘pusher/send-message’, ‘pusherController@sendMessage’)->name(‘pusher.sendmessage’);

Step 3: Send a message using Laravel Pusher and Jquery

Jquery:

Laravel:

use Pusher\Pusher;
use Validator;
class pusherController extends Controller{
public function sendMessage(Request $request) {
$return_data[‘response_code’] = 0;
$return_data[‘message’] = ‘Something went wrong, Please try again later.’;

$rules = [‘message’ => ‘required’];
$messages = [‘message.required’ => ‘Please enter message to communicate.’];
$validator = Validator::make($request->all(), $rules, $messages);
if ($validator->fails()) {
$message = implode(“
“, $validator->messages()->all());
$return_data[‘message’] = $message;
return $return_data;
}

try {
$options = [
‘cluster’ => env(‘PUSHER_APP_CLUSTER’),
‘useTLS’ => true
];

$pusher = new Pusher(
env(‘PUSHER_APP_KEY’),
env(‘PUSHER_APP_SECRET’),
env(‘PUSHER_APP_ID’),
$options
);

$response = $pusher->trigger(‘my-chat-channel’, ‘my-new-message-event’, [‘message’ => $request->message]);
if($response){
$return_data[‘response_code’] = 1;
$return_data[‘message’] = ‘Success.’;
}
} catch (\Exception $e) {
$return_data[‘message’] = $e->getMessage();
}
return $return_data;
}
}

Step 6: Implement Login Logic

/**
* @OA\Post(
* path=”/api/login”,
* summary=”Authenticate user and generate JWT token”,
* @OA\Parameter(
* name=”email”,
* in=”query”,
* description=”User’s email”,
* required=true,
* @OA\Schema(type=”string”)
* ),
* @OA\Parameter(
* name=”password”,
* in=”query”,
* description=”User’s password”,
* required=true,
* @OA\Schema(type=”string”)
* ),
* @OA\Response(response=”200″, description=”Login successful”),
* @OA\Response(response=”401″, description=”Invalid credentials”)
* )
*/
public function login(Request $request)
{
$credentials = $request->only(’email’, ‘password’);
if (Auth::attempt($credentials)) {
$token = Auth::user()->createToken(‘api_token’)->plainTextToken;
return response()->json([‘token’ => $token], 200);
}
return response()->json([‘error’ => ‘Invalid credentials’], 401);
}
