🅰️ #Angular signals 📡 are all the hype and for a good reason!

As with every new thing, it will take time to learn how it works, so there are many misconceptions like...

🤔 Angular signals will make #RxJs obsolete

Let's build a better understanding to find an answer!

🧵 1/4

The most important difference is that

📡 signals are SYNC, good for
✅ derived state (vs ngOnChanges)
✅ local component reactive state, eg inputs

🔁 #RxJs is used for ASYNC (can be sync)
✅ async orchestration
✅ latest response (race conditions)
✅ cancelation (perf)

🧵 2/4

Signals & RxJs are optimized for handling different parts of the overall state management

Because of that the optimal real-world solutions will likely include both combined using provided interop

✅ fromObservbale
✅ fromSignal

We can get the best of both worlds!

🧵 3/4

⚠️ But remember that nothing is perfect!

👴 In the past people abused #RxJs for simple sync logic 👉 which should be done with plain component logic (now with signals)

🔮 Soon people are going to abuse signals for async logic 👉 which should be done with #RxJs instead!
