Introduction: Managing Angular Application State with NgRx

Welcome to “Managing Angular Application State with NgRx”! This training is designed to provide you with an in-depth understanding of state management in Angular applications using NgRx. NgRx is a powerful library for managing state and side effects in Angular applications using a Redux-inspired approach. By the end of this course, you will be equipped with the skills to implement and manage complex application states effectively.

Prerequisites for Managing Angular Application State with NgRx

Before starting this training, you should have:

1. Basic knowledge of Angular (e.g., components, services, modules).
2. Familiarity with TypeScript and Angular CLI.
3. Understanding of basic state management concepts.
