Cron jobs are time-based scheduling tools used to automate repetitive tasks on Esadax. By using a specific syntax called a cron expression, you can define the frequency and timing of each task. This helps improve efficiency and ensures that important processes are performed consistently.

What Are Cron Jobs?

Cron jobs are automated tasks that run at predefined times. They are widely used for tasks such as:

• Backups and archiving
• Email and Slack notifications
• Updating subscription quantities

Esadax supports cron jobs for both Serverless and Edge Functions, allowing you to automate tasks with ease.

How Esadax Supports Cron Jobs

Esadax makes it simple to set up and manage cron jobs. You can add cron jobs through:

• esadax.json
• Build Output API

For example, an endpoint like https://*.esadax.app/api/cron can be used to trigger a cron job.

Common Use Cases

1. Automating Backups
2. Sending Email Notifications
3. Updating Subscription Quantities
4. Scheduling Social Media Updates

How to Add Cron Jobs

You can add cron jobs by defining them in your esadax.json file or using the Build Output API. Esadax supports the following cron expression format:

minute hour day_of_month month day_of_week

For example:

• 0 5 * * * * triggers at 5 minutes past the hour.
• * 5 * 5 * 5 triggers every minute on the 5th day of the month.

Managing Cron Jobs

When managing cron jobs, consider:

• Duration: Define how often the job runs.
• Error Handling: Ensure tasks are retried if they fail.
• Deployments: Manage multiple environments with different schedules.
• Concurrency Control: Avoid overlapping tasks.

You can also run cron jobs locally for testing.
