21 Useful Open Source Packages for React Native

Top open source libraries for React Native and what they are used for.

Intro (tl;dr)

We live in the world of a variety, yet mobile devices are dominated by two major platforms, iOS and Android. It is a two-horse race, but that doesn’t make mobile app development easy. For iOS you write code using Objective-C or Swift. For Android, you use Java. In addition to different programming languages, the tool chains are entirely different too for both of these mobile platforms.

To create app that work across devices, many modern day developers build Hybrid apps using HTML, CSS and JavaScript — as you would a web page— wrapped in native container. This way, you use (almost) one set of source code for developing applications for both iOS and Android .

In recent years, hybrid frameworks have evolved from web view to use native APIs. This cross-platform approach of developing a mobile application comes with its own pros and cons. Pros such as being less-time consuming and cost-effective, and cons include performance issues.

One of the great options that fall under the umbrella of cross-platform development is React Native. React Native was developed by Facebook and used by others such as Tesla Motors, Walmart Labs, Uber, Instagram Engineering, Discord, Wix and so on.

In a nutshell, React Native allows you to build mobile applications that look, feel and perform much more like native applications. The good thing for developers is that they can use almost the same concepts that are being used for building web applications.

The list below contains an overview of the top open source libraries that you can use in your React Native application.

React Native Navigation provides 100% native platform navigation on both iOS and Android for React Native apps. Developed and maintained by the team at Wix, is the second most commonly used package to support navigation of screens in a React Native app after react-navigation.

The reason this package is often a second preference in the community is because of its set up process. You will have to manually hook this library with iOS build and Android gradle every time you want to use it by following a number of steps.


A community package, react-native-languages is a library that helps you integrate the i18n-js library in a React Native application to internationalize and localize the application. With that, it has many utility functions that you can leverage.

For example, to get the current device’s language, you would write the following code.

React Native Firebase

React Native Firebase is lightweight JavaScript library that helps you connect your React Native app to the native Firebase SDK for both iOS and Android platform. This process aims to mirror the official Firebase SDK as closely as possible.

Even though the official SDK works with React Native, this package allows you to consume device SDKs which don’t exist on the Firebase JS SDK. To consume the official SDK in React Native, you will to opt for the web one. Things like AdMob, Analytics, Cloud Messaging (FCM), Remote Config, Performance Monitoring, Dynamic Links are not available in the official Firebase SDK.

Lastly, I leave you with the go to linting library used by almost every JavaScript developer. It is called ESLint. It is a pluggable linting utility for JavaScript and to let programmers discover issues with their JavaScript code before executing it. One great benefit of ESLint is that it gives developers the opportunity to create their own linting rules. I personally prefer to use rules provided by the team at AirBnb with some tweaks of my own.

There are other libraries that modules available for React Native for different purposes. Expect more in future since mobile development is hard when it comes to accessing to different APIs. Libraries such as axios for network calls and Apollo Client to query GraphQL APIs can also be used with React Native, as they are used with React JS. I didn’t think that they are worth mentioning here in detail. I hope the above list provides you ready made solutions to help you build better React Native applications.
