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.

Now that we have a grasp on the theoretical concept of finite state machines, we can move on to talking about XState and its main concept: finite state machines! But this time, we’ll look at it in the world of programming global state in applications.

When using XState to manage global state in an application, we should think of our state as a finite state machine. This means abandoning the previous concept of representing state as a plain JavaScript object. With XState, a component—or a surface—is a machine that can be in one of multiple predefined states. Let’s consider the user login flow. Our entire app can be in one of two states: the user is logged in or the user is not logged in. We would also need a transition mechanism for the user to move from one of the states to the other. The same goes for images on the Home surface. Every image is either in the state of being “liked” or “not...
