Are there any resources for integrating cordova with node-js to build mobile applications. how to connect nodejs to cordova for building mobile app?
Cordova is for interfacing your mobile app's client with that of the OS. Nodejs is a server-side technology. You can build both components separately... Your cordova mobile app (or native mobile app, or whatever), i.e., The Client will talk with your nodejs server, i.e., The Server.
If you've built cordova apps before, just continue as is, or if you're new, checkout some bootstrap packages like those for Sencha or Ionic or any of the million other frameworks, or start building your own app from scratch (though it's a little tough to get everything in your head sometimes)
