Node.js www - non www redirection

Question

Is there a chance to somehow redirect www to non-www URLs in node.js? Since there is no htaccess in node web server I am curious how to do that.

An updated version of jmar777's answer:

Using express

server.use((req, res, next) => {
  if (req.headers.host.startsWith('www.')) {
      const newHost = req.headers.host.slice(4)
      return res.redirect(
        301,
        `${req.protocol}://${newHost}${req.originalUrl}`,
      )
  }
  next()
})
