Using app.configure in express

Question

I found some code where they set up Express without using app.configure and I was wondering, what\'s the difference between using app.configure wit

Answer 1

It is optional and remain for legacy reason, according to the doc. In your example, the two piece of codes have no difference at all. http://expressjs.com/api.html#app.configure

Update 2015:

@IlanFrumer points out that app.configure is removed in Express 4.x. If you followed some outdated tutorials and wondering why it didn't work, You should remove app.configure(function(){ ... }. Like this:

var express = require('express');
var app = express();

app.use(...);
app.use(...);

app.get('/', function (req, res) {
    ...
});
