Signals are reshaping the way we think about state in Angular and with the introduction of NgRx Signal Store, managing complex state just became a whole lot simpler (and more fun).

In this talk, we’ll walk through a real-world Signal Store implementation that powers features like pagination, optimistic updates, and entity collections all without the boilerplate of classic NgRx. We'll showcase how to compose reactive state using withState, withEntities, and withComputed, and how to structure feature stores that are clean, scalable, and easy to maintain.

Whether you're new to signals or already experimenting with them, this session will equip you with modern patterns and best practices to supercharge your Angular state management in 2025 and beyond.

A conference talk transcript covering NgRx Signal Store for Angular state management. The speaker walks through three evolutionary approaches: component-local signals for simple state, signal stores with methods for feature-level separation, and event-driven architecture for cross-feature coordination. Key topics include Angular signals primitives (signal, computed, effect), building composable stores with withState/withComputed/withMethods/withEntities, and implementing reducers and effects for optimistic UI updates with rollback. A live demo shows a task tracker with optimistic updates and API failure rollback. The talk concludes with guidance on when to use each approach and how to migrate from NgRx component/global stores.
