6 Applying Code Conventions and Design Patterns in Angular

In this chapter, we will explore code conventions, best practices, and design patterns commonly used within Angular applications. You will also create a generic HTTP service and mock API responses using an HTTP interceptor.

Following good code conventions allows you to write code consistently. Whether you write your code solo or in a team, conventions ensure that you use similar syntax for common occurrences and follow best practices. Using good design patterns helps you to write code implementations that scale well and are battle-tested.

Code conventions and best practices focus more on processes and style-related aspects such as using the CLI, naming, using types, or preventing nested ...
