This project, generator-luke, is considered to be a "Yeoman generator".
However, it is capable of generating different types of scaffolds for various
types of projects. It is, therefore, subdivided into "sub-generators", with
each one generating a specific project type or portion thereof.
When you run yo luke, you are, technically, running the generator. However,
behind the scenes, you are also running the default sub-generator
("app"), which could also be run using yo luke:app.
While the default sub-generator creates a minimal project scaffold, which is useful for most of my projects, there are other options available. Some options produce even less than the minimal scaffold, while others create more advanced scaffolds for specific types of projects.
There are two fundamental types of sub-generators:
- Project Scaffolds - Used to create a new project
- Partials - Small, composable, project parts (aka "components")
Note: Yeoman does not officially recognize this project's terminology for "project scaffolds" and "partials", it is my own terminology.
