Question

A real-world example of using view options as the author mentioned:

var app = express.createServer();

app.configure(function() {
  app.set('views', path.join(__dirname, '..', 'views'));
  app.set('view engine', 'jade');
  app.set('view options', {
    assetVersion: 1
  });

And then in my layout.jade (base template for the app in my case):

link(rel='stylesheet', href='/static/css/' + assetVersion + '/style.css')
script(src='/static/js/' + assetVersion + '/script.js')

With this little trick, I only have to update the assetVersion variable one place to make sure that my assets aren’t cached in Varnish or other places.
