javascript - flatiron.js/union - 在哪里放置 app.use() 配置？

Question

以simple example来自 Union，我想知道在哪里可以放置通常在 app.configure 中的配置代码，例如 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());
});

有什么想法吗？服务器和路由器不接受 use()。

Union 似乎为此使用了 before 集合:

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

    // etc.
  ]
});

来自"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`.
