Taming API-s with RxJS

RxJS is a perfect choice when your application needs to communicate with a backend. While it’s helpful even when dealing with a simple CRUD-like REST API, it shows its true power in more advanced scenarios. During my talk, you will learn how to use RxJS to implement architectural patterns such as polling long-running operations, retry with exponential backoff and caching. As part of the process, you will get familiar with advanced operators such as exhaustMap or delayWhen. All examples will be runnable against a demo API which you’ll be able to use for experimentation after the talk.
