Livereload CSS and images without browser refresh

[bep]

Not sure if this is as-designed or not, but it's stated in the documentation that Hugo may not be the first static site generator to utilize live reload technology, but it’s the first to do it right so I create this issue:

• I'm used to LiveReload in Grunt (grunt-contrib-watch), and when I make changes to CSS - it will inject the changes without making a reload of the page.
• In Hugo evey change forces a browser refresh
• I have confirmed that the only change in /public is the CSS file I changed.

If your normal work flow is writing articles, then this isn't a real issue - but for pixel tweeking in CSS there is a big difference.

This would be great. The JS library I used doesn't support it, but I'd love to add this feature. It would be trivial on the GO side, it's the JS that I think would be hard. Any Javascript wizards want to add this?

Just a note:

• grunt-contrib-watch watch uses a fork of tiny-lr
• I have also used (successfully with soft reloads of CSS and JS) tiny-lr directly in Gulp (gotta love the naming of these projects).
• MIT license: https://github.com/mklabs/tiny-lr

Seems like the JS library in use supports soft reloading just fine.

If I change the hardcoded

wsHub.broadcast <- []byte({"command":"reload","path":"/x.js","originalPath":"","liveCSS":true})

To another hardoced value that matches the file I'm changing:

wsHub.broadcast <- []byte({"command":"reload","path":"/css/cc.css","originalPath":"","liveCSS":true})

Then it only loads the CSS and not the whole page.

I might have a look at this - but even if I'm an experienced developer, this Go is a blank page.

I guess one would have to

• At least for CSS files (and maybe images), send command with real file paths - but maybe only if one file changes.
• maybe also expose some configuration for liveCSS and liveImg

Added a fix for this. Works very nice on my site. I opted not to add any configuration options to turn this on/off.

I read in another thread that you consider changing the license for this project so I might just put here that I'm OK with any license (if you pull in my changes).
