React Native Check App Installed Getting Started Guide

Here's how to get started quickly with the React Native Check App Installed.

1. Installation

Using yarn:

yarn add react-native-check-app-installed

Using npm:

npm i --save react-native-check-app-installed

2. Link native dependencies

React Native version 0.60 and later autolinking will take care of the link and for version 0.59 and below you need to run this code:

react-native link react-native-check-app-installed

3. Usage

Check out the example app in the example folder.

import { AppInstalledChecker, CheckPackageInstallation } from 'react-native-check-app-install';

// To check by app name:
AppInstalledChecker
    .isAppInstalled('whatsapp')
    .then((isInstalled) => {
        // isInstalled is true if the app is installed or false if not
    });

// To check using URL (works on iOS and Android):
AppInstalledChecker
    .checkURLScheme('whatsapp') // omit the :// suffix
    .then((isInstalled) => {
        // isInstalled is true if the app is installed or false if not
    })

// To check using package name (Android only):
AppInstalledChecker
    .isAppInstalledAndroid('com.whatsapp') 
    .then((isInstalled) => {
        // isInstalled is true if the app is installed or false if not
    });

You can retrieve the list of supported app names by calling AppInstalledChecker.getAppList() or check in app-list.ts. If your app is not in the list, you will have to find out the URL scheme or package name and use either isAppInstalledIOS(url) or isAppInstalledAndroid(pacakge-name).

Android package names can be found on the Google PlayStore. For example, the URL for the Twitter app is https://play.google.com/store/apps/details?id=com.twitter.android the package name is the value of the id query parameter, i.e. com.twitter.android.
