Async Notifications in react-native

Question

ok so I have an app in react native which retrieves the information from an api. Now the api whenever it has data to send will send the data to the device and I want my app to be always running in background so as to receive the response from the api. API can send data anytime so I want to show the user data received as soon as a message arrives.

Answer 1

You need to look into Push Notifications. You can't guarantee that your app will always be running in the background, but Push Notifications allow you to send data to a user's phone even when the app isn't running. Once the user opens the notification you can perform some action, based on the data sent with the notification.

A good React Native component for push notifications is React Native Push Notification, which offers cross-platform notifications. Once you have this implemented you can create a handler which calls your API when the app is opened from a notification.
