Firebase cloud message how to send scheduled date notifications?

Question

Android

There is a ReactNative + firebase app with birthday notes. It is necessary to send push notifications to users a day before the scheduled date.
Obviously, Firebase Cloud Message should be suitable for these purposes, but I can’t figure out which way to dribble at all. Please tell me the algorithm of actions, an example and / or links to materials on the topic, otherwise I don’t even have enough brain to formulate a search query =*(

Answer 1

If I were you, I would look towards firebase cloud functions. I am sure that using the functions you can send notifications and monitor the current time. On the github, firebase has ready-made source code examples with which you don’t need to be a backend development genius.
