Signals Unleashed: Intro to NgRx Signal Store
summary
A hands‑on migration example builds a shop/cart store with NgRx Signal Store on Angular 19 (released minutes before the session), showing a working badge count, cart page, and total price that update without ZoneJS. The code uses withState and withEntities to create signals, calls updateEntity and setEntities to mutate immutably, wires async loads via withHooks onInit, and leverages deep signals and computed helpers to remove boilerplate and make the app actually simpler and faster.
