How can you run a subgenerator from within a generator?

• A. this.runWith('namespace:generatorName')
• B. this.invoke('namespace:generatorName')
• C. this.executeWith('namespace:generatorName')
• D. this.composeWith('namespace:generatorName', options)

Answer: (D)

When you want a generator to run another generator, you bring that subgenerator into the current run by composing with it. This keeps both generators in the same process and lets the lifecycle, prompts, and generated files flow together as part of one scaffold.

The best approach is to call this.composeWith with the subgenerator’s namespace and pass an options object that can include the subgenerator’s arguments and options. This is the standard way to reuse another generator inside your own, ensuring it runs in the proper sequence and shares the same environment.

For example, you’d write something like: this.composeWith('namespace:generatorName', options)

Other names aren’t the supported method for invoking a subgenerator in Yeoman; they don’t wire the subgenerator into the current generator’s lifecycle in the same reliable way.
