Are you thinking of using React Native to build cross-platform apps? When you set out on a path to build apps using React Native, you come across the question, should I use Expo or not?

React Native Background

Before we talk about Expo, here is a quick background on React Native.

I have been developing React Native apps for the last four years and I must say that things have evolved drastically in React Native, and Expo has a big role towards its success as well.

React Native is a cross-platform library that builds native mobile apps (iOS and Android) using JavaScript and React. The reason owing to its success is the fact that it uses the popular language JavaScript, in combination with the most sort after web library React to build mobile apps natively.

What is Expo?

Expo is a framework that is used to build React Native apps. It is basically a bundle with tools and services built for React Native, that will help you get started with building React Native apps with ease.

So there are two ways to build React Native apps. One using expo, and the other just using plain React Native, without Expo.

When and Why Should I Use Expo?
