Implementing Real-time Data Updates in TanStack React Charts
Provide an example of how to update a chart in real-time using WebSocket data streams and React state hooks.
import React, { useState, useEffect } from 'react';
import { Chart } from '@tanstack/react-chart';
First, import the React hooks and the Chart component from TanStack React Charts.
const MyRealtimeChart = () => {
const [data, setData] = useState([]);
useEffect(() => {
const ws = new WebSocket('wss://your-websocket-server.com/data');
ws.onmessage = (event) => {
const messageData = JSON.parse(event.data);
setData(currentData => [...currentData, messageData]);
};
return () => ws.close();
}, []);
return (
<Chart
options={/* Define your chart options here */}
data={data}
/>
);
};
This component maintains a data state, connects to a WebSocket server when the component mounts, listens for messages, and updates the data state with new values as they're received. The Chart component then uses this data for real-time updates.
