I'm trying to build a pbiviz from a custom visual I've built in Visual Studio.
Currently the build process creates one massive CustomVisuals.js where my custom visual's class resides. What I need is the stand-alone version of that class so I can zip it up into a .pbiviz. I tried simply pulling it out of CustomVisuals.js but the javascript produced there isn't valid for a pbiviz.
I tried modifying the gulp files but that didn't get me anywhere either.
Pasting to DevTools doesn't work because it doesn't support things like 'let' and 'const' which are used extensively.
How do you generate the files necessary to create a .pbiviz, namely the visual's .js & .css files, from Visual Studio?
