How to Embed Google Trends into React app


I'm attempting to embed Google Trends into React so I can adjust the parameters dynamically. I can successfully embed it directly into the index.html file.

   <script
      type="text/javascript"
      src="https://ssl.gstatic.com/trends_nrtr/1644_RC01/embed_loader.js"
    ></script>
    <script type="text/javascript">
      trends.embed.renderExploreWidget(
        "TIMESERIES",
        {
          comparisonItem: [{ keyword: "/m/030q7", geo: "", time: "now 7-d" }],
          category: 0,
          property: ""
        },
        {
          exploreQuery: "q=%2Fm%2F030q7&date=now%207-d",
          guestPath: "https://trends.google.com:443/trends/embed/"
        }
      );
    </script>

However, I need to be able to change it via user input, so it needs to be in my jsx file. I've found a useful Helmet component to assist in adding scripts

  <Helmet>
    <script
      type="text/javascript"
      src="https://ssl.gstatic.com/trends_nrtr/1644_RC01/embed_loader.js"
    />
    <script type="text/javascript">
      {trends.embed.renderExploreWidget(
        "TIMESERIES",
        {
          comparisonItem: [
            { keyword: "/m/030q7", geo: "", time: "now 7-d" }
          ],
          category: 0,
          property: ""
        },
        {
          exploreQuery: "q=%2Fm%2F030q7&date=now%207-d",
          guestPath: "https://trends.google.com:443/trends/embed/"
        }
      )}
    </script>
  </Helmet>

but I'm getting such as

'trends' is not defined no-undef

I've tried adding 'this' and 'window' but get different errors.

Can anyone assist in helping me fix this?

EDIT

Although the proposed solution didn't work for me directly, I did manage to get it working properly by taking the generated iframe tag and implement this instead.

          <iframe
            id="trends-widget-2"
            src="https://trends.google.com:443/trends/embed/explore/TIMESERIES?req=%7B%22comparisonItem%22%3A%5B%7B%22keyword%22%3A%22bitcoin%22%2C%22geo%22%3A%22US%22%2C%22time%22%3A%22today%2012-m%22%7D%5D%2C%22category%22%3A0%2C%22property%22%3A%22%22%7D&amp;tz=-480&amp;eq=q%3Dbrexit%26geo%3DUS%26date%3Dtoday%2012-m"
            width="100%"
            height="300px"
            frameborder="0"
            scrolling="0"
          />

Solution

  • First load the script url on your html file. Then use react-script-tag from npm and then write this on your component's render:

    <ScriptTag type="text/javascript">
            {'trends.embed.renderExploreWidgetTo(
      document.getElementById('widget'),
      'TIMESERIES', 
      {'comparisonItem': [{'keyword':'chicken','geo':'','time':'today 12-m'}],'category':0,'property':''}, 
      {'exploreQuery':'q=chicken&date=today 12-m','guestPath':'https://trends.google.com:443/trends/embed/'}
    )'}
    </ScriptTag>
