wess

Invokes the Less compiler in watch mode, triggering a recompilation whenever the source file or one of its (possibly indirect) import dependencies changes.

wess(path, [options])

Receives the path to the source file and options to be passed into less.render().

Returns an EventEmitter that emits the following events:

• change(path) - when one of the watched files changes
• error(err) - on compilation or watch error
• compile(output) - on successful compilation; output is as for less.render().

Call stop() on the returned object to stop watching.
