Part 1:Angular Basics and Setting Up Scalable Nx Workspaces

In this part, you’ll learn about frontend architecture and what to consider when creating your workspace. Additionally, you’ll set up your own Nx monorepo, which is ready to handle hundreds of Angular applications and libraries. After creating your Nx monorepo, you’ll learn about the newest features in the Angular framework, such as signals and standalone components. When you’re fully up to date with the latest developments of the Angular framework, you’ll do a deep dive into the Angular router, component communication, and dependency injection. Then, you will get hands-on experience with Angular directives, pipes, and animations and learn about the best practices, their impact on performance, ...
