Package size reduction, it's currently 871 KB #45
Description
I was amazed to find that adding rrule generator to our library added over 850kb to the build size of our application. Considering the library folder only contains 258kb of code the overall larger size was a shock.
The vast majority of which looks to be the moment locale files. Importing moment/locale/all accounts for over 380kb (See https://github.com/moment/moment/blob/develop/min/locales.js). Moment is a popular library and is likely already included in many projects. It would make sense to give users to ability to include the localisation support they require instead of bundling them all. Perhaps moving moment to a peer dependancy would reduce the size of this library and providing documentation on how to support more locales would improve usage and reduce file size.
