Overview of this book

Managing state in a React Native app can be challenging as it is one of the most difficult concepts to grasp while learning React Native. This is because there are so many ways to do it, and because there is a lack of clear guidelines on what should be used and why. Simplifying State Management in React Native is a comprehensive introduction for those who are new to creating robust React Native apps that will have you up to speed in no time. You’ll get to grips with the different state management strategies and libraries available. As you progress through the chapters, you’ll try out different solutions, as well as compare and choose which solution is perfectly suited to your future projects and personal preferences. Finally, you’ll create a social media clone app using all the concepts and examples that you’ve learned in this book. By the end of this book, you’ll be able to take on existing projects that use various state management strategies and libraries, and confidently make decisions about state management.

When expo is done setting up your development server, you can hit “i” for an iPhone simulator (if you’re working on a Mac computer), “a” for an android simulator (if you have Android Studio installed), or you can take your phone and use the Expo Go app.

Whichever one you choose, you will see a browser window open automatically on your device. This browser window looks like this:

If you want to see your app on your phone, you’ll find the QR code to scan in the Expo Go app right here. You will see error messages here; you can even use this page to publish your app.
