Efficient method to retrieve my app's version in a React Native environment

I have a React Native app that I created using the command react-native init. I want to define a global constant for my APP_VERSION so that I can access it in the Authentication/Login screen.

Currently, the only place I see this variable is in my package.json file. Some other users seem to be trying to extract it from there too, but they are facing challenges as well.

My plan is to create a file called src/_global/utils.js with the following code:

import * as pkg from '.package.json';

export const APP_VERSION = pkg.version;

However, when attempting this approach, I encounter exceptions indicating that the module cannot be resolved. I also tried utilizing require('.package.json'), but that approach didn't work either.

Another method I came across looks like this:

var pkg = require('.package.json');

Is there a way to successfully retrieve this version? Are there any cleaner alternatives to achieve this goal?

Thank you in advance.

Answer №1

One way to retrieve the app version for your React Native application is by utilizing the DeviceInfo library.

import DeviceInfo from 'react-native-device-info';
const appVersion = DeviceInfo.getVersion();

console.log("The current app version is", appVersion);

Answer №2

Your package.json file is not being imported correctly. A better approach would be to destructure it during the import statement.

import {name as packageName, version as packageVersion} from './path/to/package.json';
