Design a scalable component library and app architecture for a large enterprise:

This is the hottest topic in 2024/2025. Angular is moving to Signals.

The Question: "Will RxJS die?"

The Hacked Answer: "No. Signals handle synchronous state; RxJS handles async streams. They merge via toSignal() and toObservable()."

You don’t need 50 operators. Master:

With Angular 17+, Server-Side Rendering (SSR) and Hydration are defaults. Interviewers are now asking about hydration mismatches.

The Hack: ngSkipHydration

<!-- If server says "0" but client says "1" -> Mismatch Error -->
<!-- Hack: Skip hydration for dynamic parts -->
<div ngSkipHydration>
   dynamicComponentThatUsesWindow.innerWidth 
</div>

!!TOP!! Advanced Hack:
When using TransferState to pass data from server to client to avoid re-fetching data.

// Server: Set data
transferState.set<T>(MY_KEY, data);
// Client: Check if exists before HTTP call
const saved = transferState.get(MY_KEY, null);
if (saved) 
// Use saved data AND remove it to save memory
transferState.remove(MY_KEY);
