Can someone explain in depth what does this line of code mean in NodeJS:

It can be rewritten as:

module.exports = express.createServer();
var app = module.exports;

express.createServer();

The above line has the instance of express and creates a server instance (server handle) and returns the whole export class.

With the above, you are setting both module.exports as well as app to do further.
