It should be done in your application. Please check this post https://stackoverflow.com/a/54289378/5293578

I've tried the following code and it worked for me (You must put this before the default request and error handler):

/**==== File: server.js =======**/

/** Express configuration **/

// HTTPS Redirection
if (process.env.NODE_ENV === 'production') {
  app.use (function (req, res, next) {
    var schema = (req.headers['x-forwarded-proto'] || '').toLowerCase();
    if (schema === 'https') {
      next();
    } else {
      res.redirect('https://' + req.headers.host + req.url);
    }
  });
}

/** ... more configuration **/

// Default request handler
app.use(function(req, res, next) {
  // ... your code
});

// Default error handler
app.use(function(err, req, res, next) {
  // ... your code
});
