Import the widget and initialise it:

import { createCowSwapWidget, CowSwapWidgetParams } from '@cowprotocol/widget-lib'

// Initialise the widget
const widgetContainer = document.getElementById('cowswap-widget')

// instantiate your own web3 provider
const provider = window.ethereum

const params: CowSwapWidgetParams = {
  appCode: 'NAME-OF-YOU-APP', // Add here the name of your app. e.g. "Pig Swap"
  sell: { asset: 'DAI' },
  buy: { asset: 'USDC', amount: '0.1' },
}

const {updateParams} = createCowSwapWidget(
  widgetContainer,
  // Optionally, you can provide some additional params to customise your widget
  {params, provider, onReady: () => console.log('Widget ready')}
