RxJS is the JS implementation of Reactive X, an API for asynchronous programming with observable streams.

Micro Frontends Architecture

What

Micro frontends are the technical representation of a business subdomain, they provide strong boundaries with clear contracts, also they avoid sharing logic with other subdomains (DDD) Luca Mezzalira

Domain and subdomains are concepts used mainly in backend projects, but they can be used in frontend as well.

Micro Frontends is an old topic, with lots of different approaches. Same paradigm as micro-services in the backend.
