Parcel: import works but require "moment is not a function"

[kenmorechalfant]

I've installed Moment via Yarn and in my client side script (which compiles with Parcel and Babel), if I do:

var moment = require('moment')

Then, whenever I try to use it I get the error moment is not a function. Which led me to this comment from an issue on a different project to try:

var moment = require('moment')['default']

Which appears to work fine, but I'm confused why it's necessary.

import moment from 'moment' on the other hand, works fine.

I just like to use require for consistency since I use Node.

What version of moment are you using?

[kenmorechalfant]

@marwahaha 2.22.1

@kenmorechalfant why is it necessary?

Well, after adding a non-backwards compatible module system in ES2016 I'm even surprised you can load moment at all. Go ask the smart guys behind the new standard. Is there a provision to make milions of lines of "old" ES5 code to "just work" -- no. Go figure!

We should have 2 (at least) targets, one for UMD (ES5) and one for ES2016 import / export crap. That would fix some of it.

@ichernev Haven't touched that project in a couple months but it wasn't "necessary". I just preferred using require() for consistency because it was what I was already using in Node and thus used it in Parcel and was having no issues with any other of the dozen scripts I was using. I would love to just do everything in ES2016 and use regular 'imports' but Node doesn't support them yet. I know that's not Parcel/Moment's problem, and I'm just a weekend warrior I don't know all the spaghetti required to support all these different module loaders.
