How to structure app.configure in Express

Question

I use Express 3.0 alpha to build the application, but got a little confused with the configuration of the application

app.configure -> app.set "views", __dirname + "/views" app.set "view engine", "jade" app.use express.bodyParser() app.use express.methodOverride() app.configure "development", -> app.use express.logger("dev") app.configure "production", -> app.use express.logger() 

• Is the first app.configure, -> required app.configure, -> ? I have been browsing other people's apps and it seems I am not using it.

• How does ordering work for app.configure, -> ? It seems correct to put specific environments (development and production) after the first app.configure, -> , as I saw in other applications, but it does not work with my application (that is, the log does not print anything in my console at all).

Thanks in advance!

They are simply executed sequentially. The first will be called for all environments, so it doesn’t matter if it completes configure() ; it looks better. But if you look at the Express Release lineup, they are likely to disappear in the future, as they are effectively simply glorified if statements.
