Node.js: Parse JSON object

Question

I am receiving a JSON object as :

http.get(options, function(res) {
 res.on('data', function (chunk) {
 console.log('BODY: ' + chunk);
 var obj = JSON.parse(chunk);
 console.log(sys.inspect(obj));
 });
});

And it prints:

BODY: [{"buck":{"email":"[email protected]"}}]

but now I'm not able to read anything inside it. How do I get the "email" field?

Thanks

You should be doing something along the lines of:

http.get(options, function(res){
 var data = '';
 res.on('data', function (chunk){
 data += chunk;
 });
 res.on('end',function(){
 var obj = JSON.parse(data);
 console.log( obj.buck.email );
 })
});

If im not mistaken.

• Kevin Decker: The final call should be res.on('end', function(err) { ... }); nodejs.org/docs/v0.4.8/api/http.html#event_end_
• Langdon: This seems like a lot of work to get json from a server. Is there anything in node now to shorten this... I think jQuery spoiled me $.get('url', function(d) { console.log(d); })
• King Friday: Is it better to use data = [] then data.push(chunk) then JSON.parse(data.join('')) ? since strings are immutable?
