node.js + express + swig + socket.io

express + swig + socket.io 입니다.

var port=3000;

var swig  = require('swig'),
    express = require('express'),
    app = express(),
    io = require('socket.io').listen(app.listen(port));

    app.engine('html', swig.renderFile);
    app.set('view engine', 'html');
    app.set('views', public_dir);

    // Swig will cache templates for you, but you can disable
    // that and use Express's caching instead, if you like:
    app.set('view cache', false);
    // To disable Swig's cache, do the following:
    swig.setDefaults({ cache: false });
    // NOTE: You should always cache templates in a production environment.
    // Don't leave both of these to `false` in production!
    app.get('/', function (req, res) {
      res.render('index', {  
        pagename: 'awesome people',
        authors: ['Paul', 'Jim', 'Jane']
      });
      
    });

io.sockets.on('connection', function (socket) {
  // socket code
});

이렇게 작성하면 app.get 부분에서 index 에 pagename: 'awesome people', authors: ['Paul', 'Jim', 'Jane'] 이 값을 넘겨줍니다. 그럼 index.html 에선

{{ pagename|title }}


{% for author in authors %}


    {{ author }}

  
{% endfor %}

이런 식으로 쓰겠죠..
