Laravel SSE Extended

Laravel package to provide Server Sent Events functionality for your app. You can use this package to show instant notifications to your users without them having to refresh their pages.

Requirements

• PHP >= 7
• Laravel 5/6

Installation

Via Composer

$ composer require takielias/laravel-sse-extended

For Laravel < 5.5:

Add Service Provider to config/app.php in providers section

takielias\SSE\ServiceProvider::class,

Add Facade to config/app.php in aliases section

'SSE' => takielias\SSE\Facades\SSEFacade::class,

Publish package's config, migration and view files by running below command:

$ php artisan vendor:publish --provider="takielias\SSE\ServiceProvider"

Run php artisan migrate to create sselogs table.

Setup SSE

Setup config options in config/sse.php file and then add this in your view/layout file:

@include('sse::view')

Usage

Syntax:

/**
 * @param string $message : notification message
 * @param string $type : alert, success, error, warning, info
 * @param string $event : Type of event such as "EmailSent", "UserLoggedIn", etc
 */
SSEFacade::notify($message, $type = 'info', $event = 'message')

To show popup notifications on the screen, in your controllers/event classes, you can do:

use takielias\SSE\Facades\SSEFacade;

public function myMethod()
{
    SSEFacade::notify('hello world....');
    
    // or via helper
    sse_notify('hi there');
}

Customizing Notification Library

By default, package uses noty for showing notifications. You can customize this by modifying code in resources/views/vendor/sse/view.blade.php file.

Customizing SSE Events

By default, pacakge uses message event type for streaming response:

SSEFacade::notify($message, $type = 'info', $event = 'message')

Notice $event = 'message'. You can customize this, let's say you want to use UserLoggedIn as SSE event type:

use takielias\SSE\Facades\SSEFacade;

public function myMethod()
{
    SSEFacade::notify('hello world....', 'info', 'UserLoggedIn');
    
    // or via helper
    sse_notify('hi there', 'info', 'UserLoggedIn');
}

Then you need to handle this in your view yourself like this:

<script>
var es = new EventSource("{{route('__sse_stream__')}}");

es.addEventListener("UserLoggedIn", function (e) {
    var data = JSON.parse(e.data);
    alert(data.message);
}, false);

</script>

Note

Server Sent Events technology consumes server resources so use it sparingly or better use Web Sockets instead.
