I've created some new distribution options for the JavaScript SDK and have published them to github at https://github.com/MyPureCloud/platform-client-sdk-javascript-beta. The repo's readme contains an explanation of the different options and some quick examples showing how to use each one.
I'd like to get feedback about the new package to see if it fits everyone's needs. If you have any questions, comments, issues, or would like to see additional options, please reply here! I'll be collecting feedback for a few weeks and then will officially release the changes and deploy the various versions to npm and the SDK CDN.
TL;DR The SDK is has been generated as a CommonJS module for node, CommonJS module packed using browserify, AMD module for require.js, and raw source in ES6 classes.
