What is the CLI command to run a generator installed as generator-foo?

• A. yo foo
• B. yo-foo
• C. generator foo
• D. run foo

Answer: (A)

The way to run a Yeoman generator is to use the Yeoman CLI command followed by the generator’s short name. If a generator package is named generator-foo, it exposes a command called foo, and you invoke it with the command line as yo foo. The tool maps the package name’s generator- prefix to the simple name you type after yo, so you don’t include the prefix or any hyphens. That’s why yo foo is the right choice. The other options don’t fit because they either misplace the space (yo-foo), try an invalid CLI form (generator foo), or use a command that Yeoman doesn’t recognize (run foo).
