Scheduler Service

https://github.com/galniv-armis/scheduler

A simple scheduler service API server implemented in TypeScript using Node.js and MongoDB. The server implements a REST API for CRUD operations to scheduled jobs. A scheduled job can run immediately, at a specific time, or be recurring.

The service was built in TypeScript with extensive tests for all use cases and designed for performance on a large scale.
