There are numerous React Native libraries available on Github that you can quickly find and use in your project. However, since the start rating method is very tricky and often confusing in this case, we compiled a list of libraries that are commonly used by software engineers in a number of projects:

• PDF Reader: Read a PDF just with JS, no need to native libs.
• QR Code: A Barcode and QR code scan layout for react-native applications with customizable styling.
• React-native maps: It provides a Map Component that uses Apple Maps or Google Maps on iOS and Google Maps on Android.
• Face book Login: IExpo exposes a minimal native API since you can access Facebook’s Graph API directly through HTTP.
• Location: Allows reading geo location information from the device. Your app can poll for the current location.
• Camera: One can also take photos and record videos that are then saved to the app’s cache.
• Contacts: Allowing you to get contact information as well as adding, editing, or removing contacts.
• Google Login: Expo apps using a secure system web browser with native expo-app-auth. This is better than a Web View because you can reuse credentials saved on the device.
