Can I write npm package in CoffeeScript?

I’m going to suggest that you write your package in coffeescript, but only publish it in javascript. I do it like this:

• coffeescript code goes in src
• code is compiled to lib
• src is committed to my git repo, lib is in my .gitignore
• lib is published to npm, src is in my .npmignore
• the coffee-script package is in my devDependencies

You can take a look at a simple package of mine, refix, for inspiration:

• https://github.com/linus/refix
• npm install refix
