Michael Hladky is going to give a talk about how RxJS serves a very elegant way to compose events and async actions, make your code more robust and extensible. Bear in mind that this event will be in English, and the agenda is the following one:

18:30 - Arrival, drinks & networking
18:50 - Kahoot! game with prizes!*
19:00 - The talk starts
19:45 - Pizza, drinks, networking and Q&A with the speaker
20:30 - We leave the offices and those that would like to continue can do it at La Penúltima del Clot

** Description **

The web changed a lot in the past years, more and more applications provide UI’s that are heavily interactive and often also include some background tasks.

In comparison to the past years, frontend developers have to deal with new architectural problems and challenges.
Not only things like a service layer and MVC found it’s way into the frontend but also database-like structures have to be managed, updated and read from.

Especially managing data structures is one of the harder problems.
Learn the theory and praxis of Event-Sourcing and CQRS and, as crazy as it sounds, apply it in the front end.
In the end we will combine the above architectures with the facade pattern nad make our code more testable, readable, stable and scalable.
Leverage the power of reactive programming and implement the above architectures in a real live example.

** Outcome **

In a live-coding session we will learn:
• the theory of CQRS and Event-Sourcing
• how to implement CQRS and Event-Sourcing in the frontend
• orchestrate rendering and UI interaction
• why to tread rendering and UI interaction different
• dynamically compose event patterns
• optimize performance
