To refactor imperative subscribe patterns, you transform nested subscriptions into pure RxJS stream chains using higher-order mapping operators and flattening strategies to ensure code clarity and safety.

Common RxJS antipatterns include premature subscribing to inner observables and extensive manual `new Observable()` usage, which break the pure stream chain and complicate event-driven applications.

Optimize complex observable setups by applying best practices for inner observable composition, leveraging custom reusable operators, and ensuring reactive streams process events efficiently without memory leaks.

Use custom operators instead of `new Observable()` when you need to encapsulate reusable stream processing logic, as manual observable creation often introduces antipatterns that degrade code clarity and safety.

You can request a review of your RxJS code snippets to identify antipatterns, optimize reactive stream programming, and receive best practice examples for improving your structure.
