README

This package provides the custom Mattermost Notification Channel for Laravel 10+ applications.

Installation

composer require nycu-csit/laravel-mattermost

Usage

1. Add Mattermost config in the services.php

   // services.php
   'mattermost' => [
       'webhook_url' => env('MATTERMOST_WEBHOOK_URL'),
   ],

2. Use MattermostChannel in via method, and define toMattermost method which should return an instance of MattermostMessage. You can return falsy value from that method to not send the message to Mattermost.

   <?php
   
   namespace App\Notifications;
   
   use NycuCsit\LaravelMattermost\MattermostChannel;
   use NycuCsit\LaravelMattermost\MattermostMessage;
   use Illuminate\Bus\Queueable;
   use Illuminate\Notifications\Notification;
   
   class NotifyMeetingStartEnd extends Notification
   {
       use Queueable;
   
       public function __construct(private Meeting $meeting)
       {
       }
       /**
       * Get the notification channels.
       */
       public function via(object $notifiable)
       {
           return [MattermostChannel::class];
       }
   
       /**
       * Get the payload of the mattermost webhook.
       * See on the [official website](https://developers.mattermost.com/integrate/webhooks/incoming/#parameters).
       * 
       * Notification can exit early without actually sending to Mattermost
       * channel by returning from falsy value.
       */
       public function toMattermost(object $notifiable)
       {
           // exit early
           if ($this->meeting->started) {
               return null;
           }
           // https://developers.mattermost.com/integrate/webhooks/incoming/#parameters
           return (new MattermostMessage)
               ->text('...')
               ->channel('town-square');
       }
   }
