Explore reactive programming in Angular with this comprehensive conference talk by Yakov Fain at Devoxx. Dive into the world of RxJS and observables, learning how to leverage the push model for efficient data processing in your applications. Discover the power of treating UI events, HTTP, and WebSocket connections as observable streams. Gain insights into creating observables, working with operators like map and filter, and implementing error-handling techniques. Explore practical examples, including handling form inputs, making HTTP requests, and using the async pipe. Learn about hot and cold observables, sharing observables, and utilizing injectable services as mediators. By the end of this 51-minute talk, you'll have a solid understanding of reactive programming principles and their application in Angular development.
