Hi there,

I believe that this should be doable as you are already using DigitalOcean for your DNS management:

  • First add both the www and the non-www domains to your App Platform:
  • This will automatically take care of the DNS records for you so you don’t need to manually add any new recrods.
  • Then, you can to set up an HTTP redirect from the main domain name to the www subdomain. To do this, you can modify your Node.js application code to handle the redirection logic. Here is a quick example:
const express = require('express');
const app = express();
const port = process.env.PORT || 3000;

app.use((req, res, next) => {
  if (req.hostname === '') {
    return res.redirect(301, `https://www.${req.hostname}${req.url}`);

// Your other routes and middleware go here

app.listen(port, () => {
  console.log(`Server running on port ${port}`);

In this example, we create a middleware that checks if the incoming request’s hostname is If so, it redirects the request to with a 301 redirect status code.

Let me know how it goes!
