I'm iOS developer ,need to learn node js to back end services can I do that ,any one suggest good tutorials

Of course you can do that, as much as you can learn any other language. If you know JavaScript, you are already half way there. I recommend using Express as a server. If you look up how to set up an express server and app (or even a rest api) you should find good resources.

there are frameworks for that like meteor.js, sails.js, firebase, and parse.

thanks rinse for help

@heyheni which one is easier to understand

@heyheni I wouldn't use Parse. It adds a whole lot of extra stuff that you really don't need if all you want is to create an api.

With Node I usually suggest to dive right in. Think of an *intermediate level* project that will drive you and code it while making use of popular mom packages.

A fun project to build is a back-end for instant messaging app. This will have you working with express for REST API implementation, socket.io for end2end websocket communication, RethinkDb for real-time database , etc etc.

popular npm packages. fuck you too autocorrect

you can always contact me for the node.js
