I have a requirement to write data processing logic at Server-side and based on the outcome of that logic to send notifications to multiple iphones. I want to use Google Firebase to store data. But I am not sure if Google Firebase allows to write some programming logic at Firebase side to manipulate those data. Can someone please advise if I can write code logic at Google Firebase? T
To run server-side logic in response to events happening in your Firebase project, you'll want to look at Cloud Functions for Firebase. With Cloud Functions you write code that runs on Google's servers and that is called in response to activity in your Firebase project, or calls from your client-side app.
The documentation has a page with common use-cases, which includes sending notifications to users when something relevant happens in the database.
