What is Expo?
Who uses Expo?
Here are some stack decisions, common use cases and reviews by companies and developers who chose Expo in their tech stack.
The capability of style customization is one a large deal breaker for frontend SDKs. To solve this, we decided to use styled-components in our SDK, which makes it easy to add support for themes on top of our existing components. This practice reduces the maintenance effort for stylings of custom components and keeps the overall codebase clean.
I've recently switched to using Expo for initializing and developing my React Native apps. Compared to React Native CLI, it's so much easier to get set up and going. Setting up and maintaining Android Studio, Android SDK, and virtual devices used to be such a headache. Thanks to Expo, I can now test my apps directly on my Android phone, just by installing the Expo app. I still use Xcode Simulator for iOS testing, since I don't have an iPhone, but that's easy anyway. The big win for me with Expo is ease of Android testing.
The Expo SDK also provides convenient features like Facebook login,
MapView, push notifications, and many others. https://docs.expo.io/versions/v31.0.0/sdk/
We use Expo because it makes the development smoothly and avoids dealing with android and ios files, what helps with the time spent on those configurations. The framework has advanced a lot and now can be used in small productions without any problem, we have not yet had the need to eject the project, and is already in production
