Angular Tips #3

This Angular tutorial focuses on improving code structure and application performance. Abstract classes are highlighted as a means to create reusable services by centralizing shared logic, demonstrated with examples of `BookService` and `MusicService`. A generic base service is created, handling common functionality while abstracting type-specific methods. Child services then extend this base, only needing to implement the type-specific method. Lazy loading is presented as a performance optimization technique, loading modules only when needed, reducing initial bundle size. However, it's cautioned that lazy loading can negatively impact user experience if pages are large, navigation is frequent, or immediate content rendering is crucial. Preload strategies are recommended for mitigating potential delays with lazy loading. The tutorial concludes by suggesting further exploration of preload strategies for optimal performance. The author encourages feedback and welcomes comments. The tips assume prior Angular knowledge and experience. This is the third part of a series on Angular development advice.
