Support minification about html-loader HOT 4 CLOSED

This isn't easy to do well; and I learned this the hard way via jade-lang.

Also, this would be premature optimization, as minification process would just mostly remove trivial white-space.

@dashed Thanks for reviewing.

Could you please elaborate what minification process do you use that removes whitespace from within string constants?

The minifier I'm using (usemin) doesn't modify string constants such as this one, which is created by requiring a HTML template file:

module.exports = "<!-- Service order list item template. -->\n<li>\n  <a href=\"#serviceOrderDetails?id={id}\">\n    <h3>#{number} {customer}</h3>\n    <p>{description}</p>\n    <span class=\"ui-li-count\">{status}</span>\n    <p class=\"ui-li-aside\"><strong>{time}</strong></p>\n  </a>\n</li>\n"

Or are you referring to minification that should occur before the required file is bundled?

I don't think usemin is a minifier. usemin would just replace references of files with their minified counter-parts.

For example: references to something.css would be replaced with something.min.css. The existence of something.min.css is handled by another task.

I would recommend not to remove the whitespace as the savings is, most of the time, negligible. And this may hurt formatting.

@dashed Thanks for your correction. It turns out I'm actually using html-minifier. I'm still interested in having my templates minimized in production. One of the reasons is that they'll be applied several times, on a mobile device, and I see no point in wasting cycles (and battery). Also, I don't want to ship code comments to production.

@sokra Thank you for your code commit. I'll test it.
