Question

I am a NodeJS newbie and have a really simple question.

I want to store the port of the server in the application configuration. I use something like this to store it in the app config:

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());

  // My configuration:
  app.set('port', 80);
});

But how can I use the value of port? I cannot find an answer in the Express documentation.

Something like console.log('Port: ' + app.get('port')); doesn’t work (TypeError: Array.prototype.toString is not generic).

Is there a better/other way to store a simple config value with the express framework?

Answer 1

If you use Express 2.x.x then take a look at the definition of the function set(key, value):
https://github.com/visionmedia/express/blob/2.5.11/lib/http.js#L436

Line 444: this.settings[setting] = val;

So this should works:

console.log(app.setting['port']);
