[NPM] - ES Modules are not released on 1.5.3

[garyvh2]

I tried to install this library from NPM and it's not supporting ES Modules, I checked the package.json from this repository and seems like there's a configuration to cover different module formats including ES Modules, so I was confused about this problem until I found this comment #135 (comment)

The project have been stuck in 1.4.0 since then, can you make a proper release with the necessary fixes to have both ES Modules and UMD.

Just curious, how and why are you using this package as a browser/UMD module?

At this point, I'm unsure, but I believe it had to do with WCT (Web Components Tester) not transpiling the modules when running the tests, and as WCT worked with Polymer CLI, (not webpack or any related) require syntax was not supported.

I believe that was the problem, on the end I convinced my team to use Webpack + Karma, instead as it was more mature, and production friendly.

I'm running into the same issue. I'm trying to use this package from Karma, and I don't use Babel or Webpack.
