npm init -y

Install required dependencies:

npm install --save express webpack webpack-cli webpack-dev-server

Step 2: Project Structure

Create the following directory structure:

const key = 'API_KEY'
new TradingView.widget({
  debug: false,
  fullscreen: false,
  symbol: 'HK:700',
  interval: '1',
  container: 'tradingview-container',
  datafeed: new UDFCompatibleDatafeed(key),
  library_path: '/charting_library/',
  locale: 'zh',
  autosize: true,
  width: window.innerWidth,
  height: window.innerHeight,
  disabled_features: ['use_localstorage_for_settings'],
  enabled_features: [
