Nodejs & Express: How to send multiple Json variable from server to Client through response.send()

Question

I am developing an nodejs search application for itunes-search and searching some software information from my local database with express framework. The search module returns information like software name, music name through a single json variable. But now I also need Music artist details/ Software company name through another different json variable. I can simply return the song details with the bellowed code. In client sides:

$scope.search_music_data = function(data)
{
  var data="Hamdoon Soft";//Search my favourite artist name or band name
    $http({'method' : 'post', url: '/search', data: {'search_item' : data}}).
    success(function(data){ 
        $scope.artist_name = data; 
    }).
    error(function(data){ 
    })
    $scope.check = true;
}

Bellowed codes are in server sides:

In route.js

app.post('/search', search.search_music);

In search_music function currently this code is working:

ItemName="calculated data Json Data"
var response.send(ItemName);

But I also need send another calculated data like

  ItemName="calculated data Json Data"
  ArtistName="calculated data Json Data"
  var response.send(ItemName, ArtistName);

Or ItemName="calculated data Json Data" SoftWareCompnayName="calculated data Json Data" var response.send(ItemName, SoftWareCompnayName); Is it possible?I will really appreciate him/her if he/she can help me.

Answer 1

Use this in server side code. I think this will help you. This is the example of multiple value sent from server to client.

res.send({artist: artist_details, music: music_details});

In client side :

you can access it data.artist & data.music from angular controller.
