If you’re struggling to handle a large amount of data and don’t know how to improve your code readability,then reactive programming is the right solution for you. It lets you describe how your code behaves when changes happen and makes it easier to deal with real-time data. This book will teach you what reactive programming is,and how you can use it to write better applications.
Moving on,you’ll explore the RxJs API,be introduced to the problem of data traffic (backpressure),and see how you can mitigate it. You’ll also learn about other important operators that can help improve your code readability,and you’ll see how to use transducers to compose operators.
At the end of the book,you’ll get hands-on experience of using RxJs,and will create a real-time web chat using RxJs on the client and server,providing you with the complete package to master RxJs.
