How to use multiple moment plugins?

Question

I know I have to import the moment plugin if I want to use it. Like this:

import * as moment from "moment-timezone";

//here I can use moment.tr.names() etc.

But what if I want to use multiple plugins? I know that plugins in moment import moment, add their functionality and then export moment again. But if that's correct, how do I use multiple plugins?

One option is to import them under a different name like:

import * as momentJdate from "moment-jdateformatparser";
import * as momentTimezone from "moment-timezone";

Or I can merge them into one moment object like this (using deepExtend):

let moment = {};
deepExtend(moment, momentJdate, momentTimezone);

//here you should be able to use moment().toJDFString() and moment.tz.names()

But neither of those seem to be clean code. Is there a better way to do this?

Answer 1

What works for me and I think is clean-ish to import one after the other. For example:

moment = require('moment-business-days');
moment = require('moment-timezone');
moment().tz('America/New_York').businessAdd(1).startOf('day').add(7, 'hours')

It is not ideal, because it is opaque and without understanding how node works you might think the first require is pointless. But it is clean and effective.
