Overview

This advanced Angular training course teaches developers already familiar with Angular fundamentals how to build complex, enterprise-grade Angular applications. This course moves beyond basic component creation and into the intricacies of advanced routing, strategic use of NgModules alongside standalone components, and powerful reactive programming with RxJS. Learners gain in-depth knowledge of lazy loading, route guards, and nested routing, as well as understanding when and how to leverage NgModules for structuring larger applications. A significant portion of the course is dedicated to mastering RxJS for managing asynchronous operations and complex data flows. In addition, the course covers comprehensive unit testing strategies using tools like Jasmine and Karma/Jest, covering components, services, and asynchronous code.

Skills Gained

  • Implement Advanced Routing Scenarios
  • Manage Observable Subscriptions and State
  • Master RxJS for Reactive Programming
  • Write Comprehensive Unit Tests for Angular Applications
  • Mock Dependencies and Test Angular Specifics
  • Effectively Debug Angular Applications
  • Analyze and Resolve Common Angular Errors
  • Apply Best Practices for Advanced Angular Development
  • Strategically Utilize NgModules
  • Integrate Standalone Components with NgModules

Prerequisites

Students must have a solid understanding of core Angular concepts as taught in our Introduction to Angular course and be familiar with browser applications and web development tools. Practical experience in developing one or more small to medium-sized Angular applications is helpful.
