push notification in React Native

What is a push notification in React Native?

Push notifications are messages or alerts sent by the manufacturer of a user-installed application. There are two main types of notifications: foreground notifications and background notifications. Foreground notifications are a type of notification that users receive when the app is currently open and running. Background notifications are sent regardless of whether the app is now available.

Push notifications are popular in the mobile app development world for various reasons: They allow businesses to promote their products and offers at a low cost, Improve the overall user experience, and Help send transaction receipts faster. Used to convert more users.

When doing push notifications with React Native, there are three ways to set up push notifications.

  • Apple Push Notification Service (APN)
  • Expo push notification service
  • Firebase Cloud Messaging (FCM)

Apple uses APN as a cloud service for iOS notifications, and you need to register your app to access the APN. One of the benefits of APN is that you can send notifications to users without knowing their IP addresses.

FCM is provided by Google and can be integrated into your backend system or used individually. With APNs and FCMs, developers only get device tokens from their devices, but these cloud services focus on sending push messages to your device.

Expo push notification service is provided by Expo and React Native. These work for free and with Expomanaged React Native applications like the one used in this tutorial. To use push notifications with your React Native application, you must first register your app to get a push notification token. This token is a long string that uniquely identifies each device. It then stores the token in a database on the server, sends notifications, and processes incoming notifications sent.
