Angular NgRx — A Practical Guide

How NgRx works — actions, reducers, selectors, and effects — and when it is the right choice.

NgRx is powerful but easy to overuse. This guide explains it and when it actually fits.

This guide covers NgRx — the store, actions, reducers, selectors, and effects — how to structure it at scale, common pitfalls (effect loops, poorly memoized selectors), and when NgRx is worth it versus lighter options like signals or the Signal Store.
