RxJS: The Great and Terrible — Describing Asynchronous Logic Independently of the Stack
summary
Looks at using RxJS to extract and declaratively describe complex asynchronous logic (chains of intermediate states, timers, websockets, polling) so it can be integrated into React, Vue or Svelte projects without rewriting architecture. Explains where RxJS fits alongside framework-specific reactivity, dispels myths (e.g. RxJS being only for Angular), and shows how to move async logic out of components to make code more readable and maintainable.
