Task Reminder with Laravel & MongoDB
June 30, 2025📌 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.
