Bundle and optimize

[danielabar]

Figure out how to make an optimized bundle for Aurelia code. Ideally should get all the vendor js into one file, and custom app code into another, all concatenated and minified. Such that running the app would only make two http requests to get the js.

Also ideally would have sourcemaps so the bundled code can still be debugged.

Checkout latest skeleton navigation. They've got bundling and export working very nicely.

The "easiest" way to incorporate this may be to re-seed canve-viz from the skeleton, then bring over the src and test dirs.
