Functions that make call to the API and carry out the logic are located are in App\Http\Controllers\NotificationController.php The following fuctions are contained in this controller

• checkStudentModuleStatus() - Its the entry point for this app. The functions calls other necessary functions to achieve its goals
• getLiveModules() - Gets all live modules
• getProgression($module_id, $student_id) - Gets progress status of student
• notifyStudentsMidModule($student_id,$payload) - Makes the API call that sends the message to notify students mid-module
• checkIfMidDateReached($start_date, $end_date) - Checks if the module has reached mid date

To ensure that the application checks automatically each day if there are any notifications to send, a scheduler is set up We create a new command class called daily in the app/Console/Commands directory and name the scheduled artisan command daily:update We then instantiate NotificationController{} class and call the method checkStudentModuleStatus() in the handle method of class daily. We then define our scheduled task in the schedule method of the App\Console\Kernel class and set it to run once daily.

NOTE: When using the scheduler, we only need to add the following Cron entry to your server. * * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1(This is set up once for each project irrespective of the number of scheduled jobs)
