9. Task Scheduling

I use Task Scheduling to automate recurring jobs without manually managing cron tasks for each command.

🧠 Task Scheduling

I use Task Scheduling to automate recurring jobs without manually managing cron tasks for each command.


🎯 Simple Idea

Instead of writing multiple cron jobs:

👉 I define all scheduled tasks in one place

👉 Laravel handles execution using a single cron entry


🔄 How It Works

1. define scheduled tasks in application

1. system cron runs every minute

1. scheduler checks which tasks should run

1. executes the due tasks


🧩 Laravel Example

Define Scheduled Task

In app/Console/Kernel.php:

plain text
protected function schedule(Schedule $schedule)
{
    $schedule->command('report:daily')->daily();
}

Run Scheduler (Cron)

plain text
* * * * * php /path-to-project/artisan schedule:run >> /dev/null2>&1

👉 runs every minute and triggers due tasks


Example Commands

plain text
$schedule->command('emails:send')->everyFiveMinutes();
$schedule->command('cleanup:logs')->dailyAt('02:00');

🧩 What I Use It For

sending daily/weekly reports
cleaning old data
syncing systems
running maintenance tasks
scheduled notifications

🧠 Why I Use This

centralizes all scheduled jobs
easier to manage and update
avoids messy server cron configurations
improves maintainability

⚖️ Tradeoff Awareness

depends on server cron running correctly
long-running tasks should still use queues
requires monitoring for failures

📌 Practical Rule

> use scheduler for recurring tasks, queues for heavy processing


💬 Summary

I use:

Laravel Scheduler → define recurring jobs
System Cron → trigger scheduler

👉 to build systems that are automated, organized, and maintainable 👍
