I have an application developed in Angular 7 that is in the final stages of development. This application makes use of Firebase services, one of which is the Cloud Firestore.
I’m looking for a way to have a service that keeps running daily without stopping, that identifies when to send an SMS alerting the user of a commitment that he has even if he is with the closed system, or send a Push Notification using Cloud Messaging if possible.
How can I send a reminder SMS by picking up an appointment saved in the Firestore, checking the time and day and sending an SMS or Push Notification without the user needing to be connected to the system?
I believe I would have to have a service on a server running daily without stopping doing the readings in the database, but there’s something on the Internet that does this for me without me having to have a server of my own?
There are some sites that make cron Jobs for you. In other words, they do a task after a certain period of time, but in your case they would have to call some service to send the text. In other words, you would have a text messaging service and a CRON service that calls you with a certain period.
