jacksonkasi1 / qstash-headless-reminder

Streamlined backend with Express.js, Firebase, and Qstash (Headless Cron) for appointment scheduling. Qstash handles cron jobs seamlessly, retrying on failure, and allowing easy monitoring.

Qstash Headless Reminder (poc)

No need to rely on Node.js, cron, or npm anymore; Qstash will handle the cron job. If it fails, it will retry itself, and we can also monitor cron jobs.

This repository contains a simple backend for users to create appointments with doctors. Additionally, it will send push notifications to users' mobile devices when the appointment meeting is scheduled.

This repository contains a simple backend built with:

• Express.js: For handling server-side operations.
• Firebase (DB): Utilized for managing the database.
• Qstash (Headless Cron): Handling scheduled tasks seamlessly.

Cons of Legacy Node.js Cron Jobs:

• Deployment Dependency:

  • Redeploying code can disrupt Node.js cron jobs, leading to potential failures and missed tasks during deployment periods.

• Limited Monitoring:

  • Traditional Node.js cron jobs lack built-in monitoring, making it challenging to easily track, identify, and troubleshoot issues.

• Manual Retry:

  • In case of failure, manual intervention is required to trigger a retry, which may lead to delays in critical task execution.

• Management Complexity:

  • Managing traditional Node.js cron jobs lacks a centralized system, making it more complex to organize and monitor cron tasks efficiently.

• Server Dependence:

  • Running cron jobs within a Node.js server can limit server resources and hinder scalability, especially in a serverless architecture.

Pros of Qstash (Headless Cron):

• Automatic Retry:

  • Qstash automates job retry on failure, ensuring tasks are retried without manual intervention, improving reliability.

• Continuous Operation During Deployment:

  • Redeploying code does not impact Qstash cron jobs, ensuring uninterrupted operation during code updates or deployments.

• Built-in Monitoring:

  • Qstash provides a management system with built-in monitoring capabilities, simplifying the tracking and troubleshooting of cron jobs.

• Serverless Support:

  • Qstash supports a serverless approach, allowing for efficient resource utilization without the need for a dedicated server for cron jobs.

• Reliability and Predictability:

  • Qstash offers a more reliable and predictable environment for cron jobs, reducing the likelihood of task failures.
