Add Support For ES6+ in Polymer Workflow

[karthickszen]

For a web framework that is 'designed to leverage the evolving web platform on modern browsers', the lack of support for ES6 is a contradiction in terms.

Is there any way right now for me to reuse ES6 classes and services inside a Polymer element class? Specifically, can we import ES6 classes into a Polymer class, using SystemJS, along the lines of Angular2? As far as transpilers are concerned, I'm partial to babel, but at this point, I'm open to anything that works.

We have a talk tomorrow at Polymer Summit for ES6 + Polymer :)
https://www.polymer-project.org/summit

Preemptively, here are a couple of resources:

• registration from es6 classes: ES6: Better support for ES6 class syntax #2329
• babel support - ES6: vulcanize + babel produces errors b/c of strict mode issue(s) #2363
• import module defintion - github.com/PolymerLabs/IMD

Modules are the least baked and not even done at the spec level. The spec needs to define how HTML Imports + ES6 modules will work. They don't have an answer, so it's hard for us to make a recommendation as well. However, check out the Imports module definition that @justinfagnani put together (github.com/PolymerLabs/IMD). It uses HTML Imports to load component code and AMD-style syntax for defining deps.

Closing this as it's not an issue. But feel free to discuss more on the mailing list.
