Schematics: Generating custom Angular Code with the CLI
Schematics: Generating custom Angular Code with the CLI
About the Book
Besides creative aspects, programming also involves performing boring repeating tasks. Some of them can be solved by creating reusable libraries. For the rest, we can leverage code generation. This is what this book is about. It shows how to make use of Schematics, the code generator behind the Angular CLI to generate custom Angular code. Using an example, you will learn how to scaffold a new Schematics project, how to work with templates and how to manipulate existing code.
