Reactive State for Angular
A set of state management libraries for Angular apps that routes all data changes through a single predictable system using RxJS observables and Angular signals.
NgRx is a set of libraries for managing application state in Angular apps. The core idea comes from Redux: instead of letting different parts of your app update shared data in an uncoordinated way, all changes flow through a single predictable system. NgRx pairs this pattern with RxJS observables and Angular's newer signals feature, giving developers tools to keep data consistent across a complex user interface.
The library is commonly used in larger Angular applications where many components need to read and react to the same data, or where you need a clear record of how your app's state changed over time. It is a community-driven project with contributions from developers outside Anthropic and is sponsored by companies that build on it commercially.
The README itself is brief and points to the full documentation at ngrx.io, where the actual guides, API references, and migration notes live. Enterprise support options including training and workshops are listed on the NgRx website for teams that want more hands-on help.
Where it fits
- Add predictable state management to a large Angular app where many components share the same data
- Keep a full history of how your app's data changed over time for easier debugging
- Synchronize data across many Angular components without them directly modifying shared variables
