Answer 1

I know this is 2 years old but it doesn't have an accepted answer so I'm providing a complete answer:

WebApp.connectHandlers.use(function(req, res, next) {

  // Check if request is for non-www address
  if (req.headers && req.headers.host.slice(0, 4) !== 'www.') {

    // Add www. from host
    var newHost = 'www.' + req.headers.host

    // Redirect to www. version URL
    res.writeHead(301, {
      // Hard-coded protocol because req.protocol not available
      Location: 'http://' + newHost + req.originalUrl
    });
    res.end();

  } else {
    // Continue with the application stack
    next();
  }
});

You can go the opposite direction (www to non-www) with the following code:

WebApp.connectHandlers.use(function(req, res, next) {

  // Check if request is for non-www address
  if (req.headers && req.headers.host.slice(0, 4) === 'www.') {

    // Remove www. from host
    var newHost = req.headers.host.slice(4);

    // Redirect to non-www URL
    res.writeHead(301, {
    // Hard-coded protocol because req.protocol not available
      Location: 'http://' + newHost + req.originalUrl
    });
    res.end();

  } else {
    // Continue with the application stack
    next();
  }
});

You can do this with adding a piece of middleware. This should get you started:

WebApp.connectHandlers.use(function(req, res, next) {

    /* Check if request is for non-www address */
    if(...) {
        /* Redirect to the proper address */
        res.writeHead(301, {
            Content-Type': 'text/html; charset=UTF-8',
            Location: correctURL,
        });
        res.end("Moved to: " + correctURL);
        return;
    }

    /* Did not redirect - continue with the application stack */

    next();

});

I am use with this code On CLIENT SIDE:

Meteor.startup(function () {
    if (location.host.indexOf('www.domain.com') !== 0) {
        location = 'www.domain.com';
    }
});

Its verry simple and work. I hope this answer your questions. Thanks
