How to create cron jobs dynamically in firebase

Question

Does anyone know how can I set up Cron Jobs dynamically with Firebase? I want to build a rule engine using which the Client can specify the rules, actions, and schedule and based on that I need to schedule that particular rule. Since the scheduling is in the hand of the Client. I can set a predefined frequency for the JOB.

I know in Node.js I can do it with libraries like "node-schedule". But since the Client strictly wants to use Firebase and Angular. I can't use that solution

There is no way to dynamically create schedule functions with just Cloud Functions.

The two most common approaches are:

• Have a regularly scheduled Cloud Function (say every minute) that then reads the tasks from a database, and executes the tasks that are up.
• Use a separate scheduler service that has an API to create schedules, like Cloud Tasks. Doug wrote a great article about that in How to schedule a Cloud Function to run in the future with Cloud Tasks (to build a Firestore document TTL).
