this one helps. If the server supports HEAD, you can use that
Run the below code in a console from stackoverflow and you'll see the size of HTML for their home page without downloading the full page.
code :
fetch('/', {method: 'HEAD'}).then((result) => {
   console.log(result.headers.get("content-length"))
})
