How to add Google Analytics or JS code in a Streamlit app?

Using Streamlit

suryatejreddy thanks for suggestion, worked great for me.

since I deploy automatically I needed to change the file using code and came up with the following lines in the app code that checks whether there is GA script in the index.html and if not inserts it from the ‘code’ variable.

code = """<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXXXXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'UA-XXXXXXXXX');
</script>"""

a=os.path.dirname(st.__file__)+'/static/index.html'
with open(a, 'r') as f:
    data=f.read()
    if len(re.findall('UA-', data))==0:
        with open(a, 'w') as ff:
            newdata=re.sub('<head>','<head>'+code,data)
            ff.write(newdata)
