Harness the power of RxJS by solving real-life web tasks with Reactive programming; use Observables to code less

Web application code can get tangled up, which makes it hard to test and maintain. Also, asynchronous computations and HTTP requests have to be properly managed. However, with RxJS 6 you can unify, filter, and transform these streams with ease. By introducing RxJS 6 into your code, you can build clean and fault-tolerant web applications.
This course shows you how to handle work tasks and issues with RxJS 6. It helps you develop the skills you need to create Reactive applications with RxJS 6. With this course, you’ll enter the Reactive world by using Angular and vanilla JS. You will learn to execute asynchronous event handling techniques using RxJS 6.
By the end of the course, you’ll be saving precious development time by using RxJS 6. You’ll scale your own applications effectively, and use Angular framework that relies on RxJS 6.

This course offers a quick way to become familiar with Reactive Programming concepts and start using them in real-life tasks with the RxJS library. The course is focused on using RxJS for Reactive web UI in vanilla JS and Angular apps.

What You Will Learn

  • Work with the modern Reactive Extension event-based programming approach in JS
  • Use real-world examples of development practices to solve issues with less code
  • Easily implement retry on error or repeat logic for your HTTP request-ordering problems with RxJS
  • Handle HTTP requests with a few lines of code
  • Create scalable app architectures and organize convenient inter-component data flows
  • Build easily-updatable web components and combine the latest ZIP operators
  • Implement RxJS solutions in the popular modern Angular framework
  • Use RxJS patterns and anti-patterns to improve your code maintainability
