Read app.json (or exp.json) programmatically

Question

Is there a way to read the contents of app.json programmatically from within you app, so you could for example get the current version number and show it within an About screen?

Answer 1

You can access this through Constants.manifest. This includes your app.json config without any of the potentially sensitive information such as API secret keys.

import Constants from 'expo-constants';
Constants.manifest.version 

Answer 2

For Expo SDK 35, I did this:

expo install expo-constants

in your .js:

import Constants from "expo-constants";

<Text> {Constants.manifest.description} </Text>

Answer 3

For expo SDK 33 use:

 import Constants from "expo-constants";
 {`v${Constants.manifest.version}`}
