@ngrx examples

Angular 2 + ngrx examples, inspired by official redux examples.

Goal

These examples illustrate how to utilize ngrx within an Angular 2 application. This repository will be actively maintained and updated as new tools and functionality become available and best practices are established.

Contributions

As Angular 2 and ngrx are relatively new, patterns and best practices are still being established. Examples found in this repository demonstrate how I (or the project author) would structure the solution but discussion and refinement is always encouraged! Please open an issue, submit a pull request, or drop me a message on twitter to present a different approach or idea. This repository will feature the most solid, agreed upon techniques as they evolve.

Please add any additional Angular 2, ngrx, or reactive programming articles, repositories, or code samples you find useful. I will keep this list as up-to-date as possible!
