Setup Laravel Stream Log -> LSL

Aadd this in your main view/layout (usually layout/app.blade.php) file:

@include('lsl::view')

Configuration

Configuration is done via environment variables or directly in the configuration file (config/lsl.php).

<?php

return [

    // enable or disable LSL
    'enabled' => env('LSL_ENABLED', true),

    // enable or disable laravel log listener 
    'log_enabled' => env('LSL_LOG_ENABLED', true),

    // log listener  for specific log type
    'log_type' => env('LSL_LOG_TYPE', 'info,error,warning,alert,critical,debug'), // Without space

    // log listener for specific word inside log messages
    'log_specific' => env('LSL_LOG_SPECIFIC', ''), // 'test' or 'foo' or 'bar' or leave empty '' to disable this feature

    // echo data loop in LSLController
    'interval' => env('LSL_INTERVAL', 1),

    // append logged user id in LSL response
    'append_user_id' => env('LSL_APPEND_USER_ID', true),

    // keep events log in database
    'keep_events_logs' => env('LSL_KEEP_EVENTS_LOGS', false),

    // Frontend pull invoke interval
    'server_event_retry' => env('LSL_SERVER_EVENT_RETRY', '2000'),

    // every 10 minutes cache expired, delete logs on next request
    'delete_log_interval' => env('LSL_DELETE_LOG_INTERVAL', 600), 

    /******* Frontend *******/

    // eanlbed console log on browser
    'js_console_log_enabled' => env('LSL_JS_CONSOLE_LOG_ENABLED', true),

     // js notification toast library
    'js_notification_library' => env('LSL_JS_NOTIFICATION_LIBRARY', 'noty'), // 'izitoast' or 'noty'

    // notification settings
    'js_position' => 'bottomRight', // topLeft, topCenter, topRight, center, bottomLeft, bottomCenter, bottomRight
    'js_timeout' => 5000, // false, 1000, 3000, 3500, etc. Delay for closing event in milliseconds (ms). Set 'false' for sticky notifications.
];

Usage

Syntax:

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

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

use Saasscaleup\LSL\Facades\LSLFacade;

public function myFunction()
{

    LSLFacade::notify('Invoke stream log via Facade 1');

    // Some code here

    LSLFacade::notify('Invoke stream log via Facade 2');

    // Some code here

    LSLFacade::notify('Invoke stream log via Facade 3');
    
    // or via helper
    stream_log('Invoke stream log via helper 1');
    stream_log('Invoke stream log via helper 2');     
    stream_log('Invoke stream log via helper 3');
}

Customizing Notification Library

By default, package uses noty for showing notifications.

You can switch to izitoast by updating config file config/lsl.php

 // js notification toast library
'js_notification_library' => env('LSL_JS_NOTIFICATION_LIBRARY', 'izitoast'), // 'izitoast' or 'noty'

You can also, customize this by modifying code in resources/views/vendor/lsl/view.blade.php file.

Customizing LSL Events

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

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

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

use Saasscaleup\LSL\Facades\LSLFacade;

public function myMethod()
{
    SSEFacade::notify('User purchase plan - step 1', 'info', 'UserPurchase');
    
    // or via helper
    stream_log('User purchase plan - step 1', 'info', 'UserPurchase');
}

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

<script>
var es = new EventSource("{{route('lsl-stream-log')}}");

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

</script>
