For Express 4.0 I found that using application level variables works a little differently & Cory's answer did not work for me.

From the docs: http://expressjs.com/en/api.html#app.locals

I found that you could declare a global variable for the app in

app.locals

e.g

app.locals.baseUrl = "http://www.google.com"

And then in your application you can access these variables & in your express middleware you can access them in the req object as

req.app.locals.baseUrl

e.g.

console.log(req.app.locals.baseUrl)
//prints out http://www.google.com
