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.

The final call should be res.on('end', function(err) { ... }); nodejs.org/docs/v0.4.8/api/http.html#event_end_

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); });

Is it better to use data = [] then data.push(chunk) then JSON.parse(data.join('')) ? since strings are immutable?

How can I fetch req.param after parsing? Req is not an input.
