Custom Nodes

Svelvet provides the ability to customize each node to your liking. To customize your nodes, provide any of the following properties below in the node object. You can display your desired text, change colors (background, border and text), define multiple source and target handles, and set your own dimensions. Below you can find example implementations of these properties.

Current customizations include node id, data, position, sourcePosition, targetPosition, width, height, bgColor, borderColor, textColor, image, src, borderRadius, and clickCallback.


sourcePosition represents the anchor point location on the source node and is set to "bottom" by default.
targetPosition represents the anchor point location on the target node and is set to "top" by default.
