NGRX Store Book

Introduction

The book "NGRX Store Book" (author — Todd Motto, 2022, 290 pages) is a practical guide to state management in Angular applications using the NgRx library. Written in TypeScript, the book is aimed at developers who are already familiar with Angular and want to master a reactive approach to storing and processing data. Todd Motto, a renowned Angular expert and community member, offers a structured path from basics to advanced patterns.

What the book is about

The book systematically covers NgRx Store concepts, starting from the basic principles of Redux architecture (single source of truth, unidirectional data flow, pure functions) and ending with complex topics such as side effects via NgRx Effects, memoized selectors, entities, and testing. Each chapter contains code examples, diagrams, and practical exercises.

Who this book is for

The book is intended for intermediate and advanced Angular developers who want to:

• Organize state management in large projects;
• Understand reactive patterns in practice;
• Learn to write testable and maintainable code with NgRx;
• Transition from simple services to a professional architecture.

What the reader will learn

After reading, the reader will be able to:

• Set up NgRx Store in an Angular application;
• Create actions, reducers, selectors, and effects;
• Work with entities (NgRx Entity) to manage collections;
• Handle side effects (HTTP requests, timers);
• Write unit tests for Store, Effects, and selectors;
• Optimize performance using memoization and the onPush strategy;
• Integrate NgRx with Angular Router and forms.

Strengths

The main advantage of the book is its practical focus. The author not only explains theory but guides the reader through building a real application (e.g., a task management system). The code is written in TypeScript following Angular best practices. Special mention goes to the chapters on testing — a rare topic in NgRx books. The book also includes tips on migrating from outdated approaches (e.g., from ngrx/effects v8 to v12).

Who it is recommended for

We recommend this book to anyone working with Angular who wants to improve code quality, eliminate data chaos, and master a modern reactive stack. It will be useful for both team leads and individual developers striving for professional growth. For Angular beginners, the book may be challenging — it is recommended to first master the basics of the framework and TypeScript.
