Internal State and Actions

Under the hood React Flow uses Redux for state handling. If you need to access the internal state you can use the useStoreState hook inside a child component of the ReactFlow component:

Internal state

import ReactFlow, { useStoreState } from 'react-flow-renderer';
const NodesDebugger = () => {
const nodes = useStoreState((state) => state.nodes);
return null;
const Flow = () => (
<ReactFlow elements={elements}>
<NodesDebugger />

Internal actions

The internal actions of React Flow might change in the future and should not be used if it is not necessary.
You will not need this in most cases but you can also use the internal actions that are defined in the store:
import React, { useEffect } from 'react';
import { useStoreActions } from 'react-flow-renderer'
const MinZoom = () => {
const setMinZoom = useStoreActions(actions => actions.setMinZoom);
useEffect(() => {
}, []);
return null;
If you need more control you can wrap the ReactFlow component with the ReactFlowProvider component in order to be able to call useStoreState and useStoreActions outside of the ReactFlow component.
