Mastering Reactive JavaScript oleh Erich de Souza Oliveira

Key FeaturesHandle an infinite stream of incoming data using RxJs without going crazyExplore important RxJs operators that can help you improve your code readabilityGet acquainted with the different techniques and operators used to handle data traffic, which occurs when you receive data faster than you can processBook DescriptionIf youre struggling to handle a large amount of data and dont 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.The book starts with the basics of reactive programming, what Reactive Extensions is, and how can you use it in JavaScript along with some reactive code using Bacon. Next, youll discover what an Observable and an Observer are and when to use them.Youll also find out how you can query data through operators, and how to use schedulers to react to changes.Moving on, youll explore the RxJs API, be introduced to the problem of data traffic (backpressure), and see how you can mitigate it. Youll also learn about other important operators that can help improve your code readability, and youll see how to use transducers to compose operators.At the end of the book, youll 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.What you will learnGet to know the basics of functional reactive programming using RxJsProcess a continuous flow of data with linear memory consumptionFilter, group, and react to changes in your systemDiscover how to deal with data trafficCompose operators to create new operators and use them in multiple observables to avoid code repetitionExplore transducers and see how they can improve your code readabilityDetect and recover from errors in observables using Retry and Catch operatorsCreate your own reactive application: a real-time webchatAbout the AuthorErich de Souza Oliveira is a developer with 10 years of experience, mostly in JavaScript, Scala, and Java.
