How to return to the application that made the request to the browser after it has been completed?

Question

JavaScript

Good afternoon,
there was such a question, there is a mobile application that is written in ReactNative, from which a request is made to the server by opening a browser (server on django), on the page that opens, it executes some javascript code from a remote server (this happens in the form of opening windows and entering information) , then it finishes processing and an empty browser window appears in front of me, and I need the browser to close or the focus to be transferred to the application that sent the request, tell me how can this be done with less blood?

Answer 1

It seems that if you set up the scheme in the application to process certain links, then you can, at least in iOS. Google Universal links.

Answer 2

What does not suit the button now you can close this window?

and why don't you make an Ajax request and draw everything in the application?

Answer 3

Deeplinking I would look in this direction

Answer 4

Why not use WebView?
