Bunnycron is a job scheduling module trigged by your node.js process. Bunnycron will schedule a job based on a cron syntax textfile in your project directory, so you can keep your job scheduling definition in your git repository. With a lock machanism provided by Redis, Bunnycron will prevent the same job running multiple times within a cluster. It provides a clean user interface to monitor your jobs and their statuses.
Install via npm:
npm install bunnycron
