Node.js Question

How do you detect the environment in an express.js app?

How do you detect what environment an expressJS app is running in? (development, test, production?). There's nothing in

process.env
indicating an environment...

I'm aware that you can declare variables in your configuration file under each environment, but that doesn't help if you are dynamically loading modules...

Answer

You can either check the environment by checking the app.settings.env (this will work in Express), or you can do it in a more direct way by checking process.env.NODE_ENV (the environment is the one found in that variable or 'development' by default < this also works in other libraries such as Socket.IO etc).
