Implementing Memorization for Performance
Illustrate using TypeScript with React's useMemo hook to optimize the performance of a TanStack React Chart by preventing unnecessary re-renders.
import { useMemo } from 'react';
import { Chart } from 'tanstack-react-charts';
Import necessary hooks and components.
const processData = (data) => {
// Assume this function processes and aggregates data for the chart
return data.map(item => ({...item, value: item.value * 2}));
};
Define a function for data processing. This is a placeholder for any data manipulation required before feeding it into the chart.
const MyChartComponent = ({ data }) => {
const memoizedData = useMemo(() => processData(data), [data]);
return (
<Chart
options={{
data: memoizedData
}}
/>
);
};
Use the useMemo hook to memoize processed chart data. This prevents re-processing of data on every render, only updating when the 'data' prop changes.
