Whats the significance of bin/www

app.js

contains all the middleware(body-parser,morgan,etc) and routes. it exports app object at the last.

www

here it creates a httpServer and passes app as the handler var server = http.createServer(app); besides also sets the port server.listen(port); also sets the functions to be called if there is an error while starting the server: server.on('error', onError);

Explanation so, basically it removes all the create and start server code from your app.js and let you focus only on the application logic part. Note: If you see in package.json file you would note this:

"scripts": {
  "start": "node ./bin/www"
}

this means if you type in terminal npm start then it will automatically start the ./bin/www file.
