Why not use Yeoman?

I love Yeoman and use it often.

However I found myself spending more time coding on the generator part than on the component part. Having to run the generator over an over again to check if the generated output is a cumbersome task and not really developer friendly.

Not to mention the syntax highlighting problem when writing generator code.

So while Yeoman is great for many things, it just didn't fit the requirements for Angular Express.

Angular Express is focused on developer satisfaction to make the creation and maintenance of boilerplates and components as easy as possible.
