<Background />

Source on GitHub

The <Background /> component makes it convenient to render different types of backgrounds common in node-based UIs. It comes with three variants: lines, dots and cross.

import { useState } from 'react';
import { ReactFlow, Background, BackgroundVariant } from '@xyflow/react';
 
export default function Flow() {
  return (
    <ReactFlow defaultNodes={[...]} defaultEdges={[...]}>
      <Background color="#ccc" variant={BackgroundVariant.Dots} />
    </ReactFlow>
  );
}

Props

• id?: string When multiple backgrounds are present on the page, each one should have a unique id.
• color?: string Color of the pattern.
• bgColor?: string Color of the background.
• className?: string Class applied to the container.
• patternClassName?: string Class applied to the pattern.
• gap?: number | [number, number] The gap between patterns. Passing in a tuple allows you to control the x and y gap independently.
• size?: number The radius of each dot or the size of each rectangle if BackgroundVariant.Dots or BackgroundVariant.Cross is used. This defaults to 1 or 6 respectively, or ignored if BackgroundVariant.Lines is used.
• offset?: number | [number, number] Offset of the pattern.
• lineWidth?: number The stroke thickness used when drawing the pattern.
• variant?: BackgroundVariant Variant of the pattern.
• style?: CSSProperties Style applied to the container.

Examples

Combining multiple backgrounds

It is possible to layer multiple <Background /> components on top of one another to create something more interesting. The following example shows how to render a square grid accented every 10th line.

import { ReactFlow, Background, BackgroundVariant } from '@xyflow/react';
 
import '@xyflow/react/dist/style.css';
 
export default function Flow() {
  return (
    <ReactFlow defaultNodes={[...]} defaultEdges={[...]}>
      <Background
        id="1"
        gap={10}
        color="#f1f1f1"
        variant={BackgroundVariant.Lines}
      />
 
      <Background
        id="2"
        gap={100}
        color="#ccc"
        variant={BackgroundVariant.Lines}
      />
    </ReactFlow>
  );
}

Notes

• When combining multiple <Background /> components it’s important to give each of them a unique id prop!
