To integrate TradingView charts in a TypeScript project, you can follow these basic steps:

Add TradingView's charting library to your project using a package manager such as NPM:

npm install tradingview/charting_library

Create a wrapper component that will handle the initialization of the charting library and the rendering of the chart. Here is a basic example of such a component:


index.ts
import { Component } from 'react';
import * as TradingView from 'tradingview/charting_library';

type Props = {
  symbol: string;
  interval: string;
};

class TradingViewChart extends Component<Props> {
  chartContainerRef = React.createRef<HTMLDivElement>();

  chart?: TradingView.IChartingLibraryWidget;

  componentDidMount() {
    if (this.chartContainerRef.current) {
        // Create the charting widget
        this.chart = new TradingView.widget({
            symbol: this.props.symbol,
            interval: this.props.interval,
            container_id: this.chartContainerRef.current.id,
            library_path: '/charting_library/',
            // Other configuration options
        });
    }
  }

  componentWillUnmount() {
    // Call the `remove` method to clean up the chart when the component is unmounted
    if (this.chart) {
        this.chart.remove();
    }
  }

  render() {
    return (
      <div
        id="tv_chart_container"
        style={{ width: '100%', height: '100%' }}
        ref={this.chartContainerRef}
      />
    );
  }
}

In your application code, render the TradingViewChart component with the required symbol and interval props:


index.ts
import TradingViewChart from './TradingViewChart';

function App() {
  return (
    <div style={{ width: '100%', height: '500px' }}>
      <TradingViewChart symbol="AAPL" interval="D" />
    </div>
  );
}

Note that this is just a basic example, and the component can be extended and customized to meet your specific use case. Also, make sure to refer to the TradingView documentation for the full list of configuration options and available methods.
