I have used CoffeeScript for a while. Now I need to write a npm package, can I write it in CoffeeScript, or I should compile CoffeeScript into JavaScript?
I'm going to suggest that you write your package in coffeescript, but only publish it in javascript. I do it like this:
src
lib
src
is committed to my git repo, lib
is in my .gitignore
lib
is published to npm, src
is in my .npmignore
coffee-script
package is in my devDependencies
You can take a look at a simple package of mine, refix, for inspiration:
npm install refix
