Minification and Vulcanization ought to be simplified

I'd like to be able to use Polymer on a production environment, and Polymer has a nice shopping cart style, but it isn't ideal.

1. It only downloads individual components, unminified, and without their dependencies (bower makes this step easier, but all files are still unminified)

2. You end up with a couple <link rel="import" /> tags in the <head>, but they rely on multiple dependencies, resulting in numerous http requests (hence the need to vulcanize)

3. After vulcanizing, you need to minify it yourself

I hope someday soon I'll be able to check out my favourite elements to the shopping cart, and download 1-2 minified files for production use: (1) the polymer components vulcanized and minified, (2) webcomponentsjs - which I understand must be loaded outside of the polymer components.

The a la carte nature of web components means you only need to load the components you need. If someone only wants to use a paper-button on their page, why should they be forced to request a vulcanized build of all the minified components? How would this work in practice?

Thanks for your reply. I forgot that Polymer was designed to be modular in case others want to use a mix of components from different vendors. I guess for now I need to figure out grunt in order to minify my vulcanized components.

If you want a simple build setup, we provide an all-in-one minification tool for gulp called polybuild: https://www.npmjs.com/package/polybuild.

You can also copy the gulp configuration of the Polymer Starter Kit: https://github.com/polymerelements/polymer-starter-kit
