Use XFC's transpiled code, not source

[pgross41]

This (cerner-smart-embeddable-lib.js#L3):

import Provider from 'xfc/src/provider';

Should be this:

import Provider from 'xfc/lib/provider';

Or better yet:

import { Provider } from 'xfc';

---

That change will allow apps to import the ES6 module

import 'cerner-smart-embeddable-lib';

Instead of plucking out the pre-built version

import './vendor/cerner-smart-embeddable-lib-1.3.0';

PowerChart errors with the ES6 module because of this spread operator in XFC (possibly other reasons too but this is the first error). It works if cerner-smart-embeddable-lib includes the lib version though.

Using the ES6 module will also allow apps to disable XFC logging by defining process.env.NODE_ENV per the readme. Thus partially resolving these issues:

• https://github.com/cerner/xfc/issues/45
• https://github.com/cerner/f-twelve/issues/5

The info about process.env.NODE_ENV should also be documented on this project's readme. There is no way a user would know the logging is coming from a dependency nor how to disable it.

I say the issues are "partially resolved" because non-webpack users will still have no way to disable logging. XFC should probably provide a run-time config to disable logging so that users of the pre-build .min.js version of cerner-smart-embeddable-lib can turn it off and utilize f-twelve.
