Do Mobile Apps have backend?

The backend is a necessary part of a mobile app that stores, secures, and processes the data. A backend app is like a server for the users to sort the required information. One can say that it refers to the activities that happen behind the scenes when you are performing a task on an app.

You can connect your Android app with the NodeJS backend by RESTful API or GraphQL . Java has a convenient way handling API calls by using the HTTP Client library.

Node. js works independently, it cannot be installed on Android OS as it is a server service that simply responds to requests.12 May 2021
