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.

Note: Firebase, Qstash data, and keys in this repository will be deleted soon.
