Hi guys,

Has anyone tried embedding a widget/plug-ins in their shiny app?
I was looking to integrate one of Tradingviews widgets in simple iframe format into my app, however without success.

Generally found little on this topic, but tried two ways directly in UI:
1. via iframe

              div(
                iframe(width = "1000", height = "500",
                       url_link = "https://s3.tradingview.com/external-embedding/embed-widget-market-overview.js")
              )

2. via HTML tag

              tags$div(
                HTML('
                     <div class="tradingview-widget-container">
                     <div class="tradingview-widget-container__widget"></div>
                     <div class="tradingview-widget-copyright"><a href="https://www.tradingview.com/markets/cryptocurrencies/prices-all/" rel="noopener" target="_blank"></div>
                     <script type="text/javascript" src="https://s3.tradingview.com/external-embedding/embed-widget-screener.js" async>
                     {
                     "width": "100%",
                     "height": "100%",
                     "defaultColumn": "overview",
                     "screener_type": "crypto_mkt",
                     "displayCurrency": "USD",
                     "locale": "en",
                     "transparency": true
                     }
                     </script>
                     </div>
                     ')
              )

Looking forward to your thoughts on this, thank you!

Inserting the HTML embed code from the trading view site should work. I'd recommend saving it as a standalone HTML file then inserting it into the app's UI with includeHTML()

trade_widget.html

<!-- TradingView Widget BEGIN -->
<div class="tradingview-widget-container">
  <div class="tradingview-widget-container__widget"></div>
  <div class="tradingview-widget-copyright"><a href="https://www.tradingview.com" rel="noopener" target="_blank"><span class="blue-text">Market Data</span></a> by TradingView</div>
  <script type="text/javascript" src="https://s3.tradingview.com/external-embedding/embed-widget-market-overview.js" async>
