📌 Building a Task Reminder App

This guide shows how to set up a Laravel app using MongoDB to implement a task reminder system with authentication, CRUD, and scheduled email reminders.

Prerequisites

• MongoDB Atlas cluster
• PHP + MongoDB extension
• Composer, NPM
• Basic Laravel & MongoDB knowledge

1. Start Laravel Project & Add MongoDB

composer create‑project laravel/laravel task‑reminder
cd task‑reminder
composer require mongodb/laravel-mongodb

Then in config/database.php, add:

'connections' => [
  'mongodb' => [
    'driver'   => 'mongodb',
    'dsn'      => env('MONGODB_URI'),
    'database' => 'YOUR_DB',
  ],
],

2. Authentication with Breeze

composer require laravel/breeze --dev
php artisan breeze:install
php artisan migrate
npm install && npm run dev
php artisan serve

3. Add Ping Route to Test MongoDB

Route::get('/ping', function() {
  try {
    DB::connection('mongodb')->command(['ping'=>1]);
    return ['msg' => 'MongoDB is accessible!'];
  } catch (Exception $e) {
    return ['msg' => 'Not connected: '.$e->getMessage()];
  }
});

4. Task Model & Controller (CRUD)

php artisan make:model Task --resource --controller

// in Task.php
use MongoDB\Laravel\Eloquent\Model;
class Task extends Model {
  protected $connection='mongodb';
  protected $fillable=['title','description','due_date','email','reminder_time','last_notification_date'];
}

Controller handles index, create, store, edit, update, destroy. Format dates with Carbon, link tasks to auth()->user()->email.

5. Views with Bootstrap

• Create form input: title, description, due_date, reminder_time
• Edit form similar
• Index page lists tasks, with Edit/Delete buttons

6. Send Reminder Emails

php artisan make:command SendTaskReminders

// handle() in SendTaskReminders.php
$now = Carbon::now();
$tasks = Task::whereNull('last_notification_date')
  ->where('reminder_time','>=',$now->subMinutes(10))
  ->get();
foreach($tasks as $task){
  Mail::raw("Reminder: {$task->title}", function($msg) use($task){
    $msg->to($task->email)
        ->subject("Task Reminder: {$task->title}");
  });
  $task->last_notification_date = $now;
  $task->save();
}

7. Schedule the Command

// in console.php
Schedule::command('app:send-task-reminders')->everyMinute();
// add cron: * * * * * php /path/artisan schedule:run

Conclusion

You’ve built a full task reminder system with MongoDB storage, user auth, CRUD, and scheduled email notifications using Laravel.
