Mobile Application Notification

I am a react native developer and have been playing around stuff for quite some weeks now.

I recently stumbled upon a problem, How to send notifications in react native apps when the app is not loaded in the memory.

Like notification in the app that can be triggered from the server side.

Are you talking about something like Android/iOS notifications? Normally you send notifications via FCM or APNS, the device receives the notification and displays it to the user and/or starts your app.

Yes Like YouTube notification for subscribed creators. 

I'll definately look in this, Can FCM or APNS be programmed or some sort of service is needed to be used.

Firebase Cloud Messaging (FCM) is a service by Google. Apple Push Notification Service (APNS) is the same thing, by Apple. You can also use FCM to talk to Apple devices (which then talks to APNS under the hood).

 

When your app is started, it registers itself with either of these services, and receives a unique token. You send that token to your back end, which needs to remember which device has which token.

 

When you want to send a notification, your back end talks to FCM and/or APNS and sends a push notification for one or more token(s). The service then takes care of sending the notification to the device.

Thanks @Eigenvektor got the point there.
