How do you compose with a generator by using its npm package name?

• A. this.composeWith(require.resolve('generator-name'), options)
• B. this.composeWith('generator-name', options)
• C. this.useWith('generator-name')
• D. this.chainWith('generator-name')

Answer: (A)

When you want to reuse another generator inside your own, you compose with it. The composeWith method needs a module path to load that generator. Using require.resolve with the package name turns the npm package into an exact file path to its main module, which Yeoman can safely require and run. So calling this.composeWith(require.resolve('generator-name'), options) loads the generator installed under that npm package and runs it as part of your workflow. This is more reliable than passing just the package name, because require.resolve gives a precise, resolvable path even in complex project layouts. The other forms aren’t proper ways to reference a generator for composition.
