RxJS Essentials

Video description

Libraries of reactive extensions exist in many programming languages. RxJS is a popular library of reactive extensions for JavaScript. In this course, you'll explore RxJS and how it's used to transform and compose streams of data. RxJS promotes the push model, where the algorithms of your application handles data by applying a number of composable functions. The push model allows you to eliminate polling for data that may not even be available. Splitting the business logic into separate functions makes the code easier to read and modify. RxJS is not a framework and can be used in any JavaScript app. To best follow this course, learners must be familiar with JavaScript syntax and callback functions, and should have current versions of Node.js and Visual Studio Code loaded on their computers.

  • Understand how to bring reactive programming to your JavaScript apps
  • Create a pathway forward from imperative to functional programming
  • Pick up the ability to create observable data streams
  • Explore the roles of observers and subscribers
  • Discover how to apply and compose operators to process the data emitted by observables
  • Master the ability to handle errors
  • Understand how to compose multiple data streams
