express without a template

Is there a reason why I should avoid doing this?

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set("view options", {layout: false});
  app.use(express.static(__dirname + '/views'));
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

var html_dir = './views/';

app.get('/', function(req, res){
    res.sendfile(html_dir  + "login.html");
});
