Panning and Zooming
The default pan and zoom behavior of React Flow is inspired by slippy maps . You pan by dragging and zoom by scrolling. You can customize this behavior easily with the provided props:
panOnDrag
: default:true
selectionOnDrag
: default:false
(available since 11.4.0)panOnScroll
: default:false
(OverwriteszoomOnScroll
)panOnScrollSpeed
: default:0.5
panOnScrollMode
: default:'free'
.'free'
(all directions),'vertical'
(only vertical) or'horizontal'
(only horizontal)zoomOnScroll
: default:true
zoomOnPinch
: default:true
zoomOnDoubleClick
: default:true
preventScrolling
: default:true
(browser scroll behavior is prevented)zoomActivationKeyCode
: default'Meta'
panActivationKeyCode
: default'Space'
(available since 11.4.0)
Default Viewport Controls
As mentioned above, the default controls are:
- pan: drag mouse
- zoom: scroll
- create selection: Shift + drag
import { useCallback } from 'react';
import {
ReactFlow,
addEdge,
useEdgesState,
useNodesState,
} from '@xyflow/react';
import '@xyflow/react/dist/style.css';
import { initialNodes } from './nodes';
import { initialEdges } from './edges';
function Flow() {
const [nodes, setNodes, onNodesChange] = useNodesState(initialNodes);
const [edges, setEdges, onEdgesChange] = useEdgesState(initialEdges);
const onConnect = useCallback(
(connection) => setEdges((eds) => addEdge(connection, eds)),
[setEdges],
);
return (
<ReactFlow
nodes={nodes}
edges={edges}
onNodesChange={onNodesChange}
onEdgesChange={onEdgesChange}
onConnect={onConnect}
/>
);
}
export default Flow;
Figma-like Viewport Controls
If you prefer figma/sketch/design tool controls you can set panOnScroll={true}
and selectionOnDrag={true}
:
- pan: Space + drag mouse, scroll, middle or right mouse
- zoom: pitch or cmd + scroll
- create selection: drag mouse
import { useCallback } from 'react';
import {
ReactFlow,
addEdge,
SelectionMode,
useEdgesState,
useNodesState,
} from '@xyflow/react';
import '@xyflow/react/dist/style.css';
import { initialNodes } from './nodes';
import { initialEdges } from './edges';
const panOnDrag = [1, 2];
function Flow() {
const [nodes, setNodes, onNodesChange] = useNodesState(initialNodes);
const [edges, setEdges, onEdgesChange] = useEdgesState(initialEdges);
const onConnect = useCallback(
(connection) => setEdges((eds) => addEdge(connection, eds)),
[setEdges],
);
return (
<ReactFlow
nodes={nodes}
edges={edges}
onNodesChange={onNodesChange}
onEdgesChange={onEdgesChange}
onConnect={onConnect}
panOnScroll
selectionOnDrag
panOnDrag={panOnDrag}
selectionMode={SelectionMode.Partial}
/>
);
}
export default Flow;
In this example we also set selectionMode={SelectionMode.Partial}
to be able to add nodes to a selection that are only partially selected.
