less-to-js

What it does

Turns .less files into .js files that can run in the browser or in node. (just does nothing in node)

hello.less

.hello {
  .world {
    color: lighten(red, 20%);
  }
}

turns into

hello.less.js

(function(e){if("undefined"!=typeof document){var t=document;if(t.less_to_js__inserted=t.less_to_js__inserted||{},!t.less_to_js__inserted[e]){t.less_to_js__inserted[e]=!0;var s=t.createElement("style");s.setAttribute("type","text/css"),"textContent"in s?s.textContent=e:s.styleSheet.cssText=e,t.getElementsByTagName("head")[0].appendChild(s)}}}(".hello .world{color:#f66}"));

Which can then be used in the browser or server. For example requried in a project using browserify

app.js

require('./hello.less.js');
