Create a composite StyleBook 编辑

An important and powerful feature of StyleBooks is that they can be used as building blocks for other StyleBooks. A StyleBook can be imported into another StyleBook and it can be referred to as a type that is used by components of the second StyleBook similar to a Nitro built-in StyleBook.

For example, you can use the basic-lb-config StyleBook that you built in the previous section, to build another StyleBook called composite-example. To use the “basic-lb-config” StyleBook, you have to import it in the new StyleBook in the import-stylebooks section.

Build your StyleBook

The new StyleBook would look as follows:

name: composite-example
namespace: com.example.stylebooks
