WeaveStageNode

Overview

The WeaveStageNode class represents the root container of the canvas in Weave.js applications. Built on top of Konva’s Stage class, the WeaveStageNode manages the overall canvas environment where all other nodes (such as Layers, Groups, and Shapes) are rendered.

As the top-level visual node, it is responsible for setting up the base coordinate system, initializing the layers, and serving as the anchor point for user interactions like panning, zooming, and resizing.

The class extends the WeaveNode class
