<BaseEdge />

Source on GitHub (opens in a new tab)

The <BaseEdge /> component gets used internally for all the edges. It can be used inside a custom edge and handles the invisible helper edge and the edge label for you.

import { BaseEdge } from 'reactflow';
 
export function CustomEdge({ sourceX, sourceY, targetX, targetY, ...props }) {
  const [edgePath] = getStraightPath({
    sourceX,
    sourceY,
    targetX,
    targetY,
  });
 
  return <BaseEdge path={edgePath} {...props} />;
}

Props

#id
string
#style
#interactionWidth
number
The width of the invisible area around the edge that the user can interact with. This is useful for making the edge easier to click or hover over.
#path
string
The SVG path string that defines the edge. This should look something like 'M 0 0 L 100 100' for a simple line. The utility functions like getSimpleBezierEdge can be used to generate this string for you.
#markerStart
string
The id of the SVG marker to use at the start of the edge. This should be defined in a <defs> element in a separate SVG document or element.
#markerEnd
string
The id of the SVG marker to use at the end of the edge. This should be defined in a <defs> element in a separate SVG document or element.
#label
string | React.ReactNode
The label or custom element to render along the edge. This is commonly a text label or some custom controls.
#labelX
number
#labelY
number
#labelStyle
#labelShowBg
boolean
#labelBgStyle
#labelBgPadding
[number, number]
#labelBgBorderRadius
number

Notes

  • If you want to use an edge marker with the <BaseEdge /> component, you can pass the markerStart or markerEnd props passed to your custom edge through to the <BaseEdge /> component. You can see all the props passed to a custom edge by looking at the EdgeProps type.
