Altering URL while transmitting file via Express

When attempting to send an HTML file as a response, I am experiencing an issue where the current URL is being maintained. Despite my attempts to use the location method, it does not seem to work. Ideally, I would like the functionality to redirect to a new URL after sending the response.

The original URL in question is: localhost/login

This is the desired outcome:

res.location('/live').sendFile(path.join(__dirname, "../pages/live.html"));

I have been striving for this result:

  • Desired URL in browser: localhost/live
  • Displaying the rendered HTML file

Is there an error in the way I am approaching this? Any advice would be greatly appreciated.

Answer №1

Make an AJAX request to fetch data in HTML format, then dynamically add it to the document.

Example code snippet for Front-End:

fetch('/your-route')
    .then(response => response.text())
    .then(data => {
        document.write(data)
    })

Answer №2

When utilizing the .location method, you are essentially setting the response header field of location to "/live". However, in order to actually change the URL, a status code of 302 must be added. It's important to note that adding a status code of 302 will result in a redirect, causing the send file not to be displayed as the browser attempts to GET "/live". To ensure the html file is returned, a listener for GET /live must be implemented. Alternatively, you can use res.redirect to directly redirect to the necessary "/live" handler.
