This is a very large release! The long term of Konva
API is to make it simpler and faster. So when possible I am trying to optimize the code and remove unpopular/confusing API methods.
BREAKING:
Konva.Collection
is removed.container.children
is a simple array now.container.find()
will returns an array instead ofKonva.Collection()
instance.Konva.Collection
was confusing for many users. Also it was slow and worked with a bit of magic. So I decided to get rif of it. Now we are going to use good old arrays.
// old code:
group.find('Shape').visible(false);
// new code:
group.find('Shape').forEach((shape) => shape.visible(false));
- argument
selector
is removed fromnode.getIntersection(pos)
API. I don't think you even knew about it. Konva.Util.extend
is removed.- All "content" events from
Konva.Stage
are removed. E.g. instead ofcontentMousemove
just usemousemove
event.
New features:
- All updates on canvas will do automatic redraw with
layer.batchDraw()
. This features is configurable withKonva.autoDrawEnabled
property. Konva will automatically redraw layer when you change any property, remove or add nodes, do caching. So you don't need to calllayer.draw()
orlayer.batchDraw()
in most of the cases. - New method
layer.getNativeCanvasElement()
- new
flipEnabled
property forKonva.Transformer
- new
node.isClientRectOnScreen()
method - Added
Konva.Util.degToRad
andKonva.Util.radToDeg

inherit
option is removed fromvisible
