Answer 1

"paths" should be in "compilerOptions" section, not in root of tsconfig.json

Answer 2

I had a similar issue with "moment" I have import like below and it does work.

import * as moment from 'moment';

Answer 3

Note that the import will seem fine while developing by importing moment this way, but you may get an AOT error when doing a prod compile, something like, "can not use reference" or some such like that. To not elaborate over much, this has to do (as I understand it) with some CommonJS modules. Moment is very popular, so it seems to come up quite a bit.

To get around that one (which I ran into a couple of weeks ago), set "moment" to a const:

import * as moment from 'moment':

(later where you declare consts)

const _moment = moment;

And then you use _moment in your code.
