javascript - html canvas shape blur filter

There must be a way to do this. I have drawn a shape with the html5 canvas and I would like to blur it. As far as I know there is no native method so I assume a js library is needed. The problem is most libraries only blur images like this one for example. Is this possible?

myContext.filter = 'blur(10px)';

The CanvasRenderingContext2D.filter property of the Canvas 2D API provides filter effects like blurring or gray-scaling. It is similar to the CSS filter property and accepts the same functions. https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/filter

it's still experimental but is supported by chrome & firefox atm.
