Cron Scheduler with FastQ, Fork and PM2

This project uses node-cron, fastq, child_process.fork, and PM2 to schedule cron jobs, process tasks in a queue, run tasks in child processes, and manage the application, respectively.

Features

node-cron: Schedules cron jobs in Node.js.
fastq: Manages a queue of tasks with variable concurrency.
PM2: Process manager to keep your application running.
child_process.fork: Runs tasks in child processes for improved performance.

Configuration

Update the schedules array in index.js to change the cron schedules. Modify the FastQ concurrency setting to change the number of tasks executed in parallel.

const queue = fastq.promise(logWorker, 10); // Concurrency set to 10
