I don't understand how this can be considered dependency free in any sense - it has a dependency on Moment.js, which is a fairly large (and very popular and good) library for working with dates in JavaScript. Without Moment.js, this library would not work - therefore it is "dependent" on that. This is what the word "dependency" means. Just because you can bundle up that library in the dist doesn't mean it's not a dependency.
