Question

Taking the simple example from Union, I am wondering where I can put configuration code that usually goes in app.configure, like passport.js:

app.configure(function() {
  // Initialize Passport!  Also use passport.session() middleware, to support
  // persistent login sessions (recommended).
  app.use(passport.initialize());
  app.use(passport.session());
});

Any ideas? server and router don’t accept use().

Union appears to use the before collection for this:

var server = union.createServer({
  before: [
    connect.session({ secret: 'keyboard cat' }), // for `passport.session()`
    passport.initialize(),
    passport.session(),

    // etc.
  ]
});

From the “API” documentation:

@option before {Array} 
    The `before` value is an array of middlewares, which are used to route and serve incoming 
    requests. For instance, in the example, `favicon` is a middleware which handles requests 
    for `/favicon.ico`.
