Making a node.js component

[André Simões]

Hi. I'm trying to create a component in Node.js that consumes two external APIs.

The code of my component is something like:

var api1 = require('./api1');
var api2 = require('./api2');
var component = { api1: api1, api2: api2 };
module.exports = component;
--------------------

api1 is something like this:

var api1 = { testFunc: function(stuff,callback){ // do http request & callback(result) } }
module.exports = api1;

--------------------

I've one endpoint on nodejs where i'm trying to use this component, like this:

var component = require('../../component');
component.api1.testFunc(1, function(result) {return res.json(200, result.data);});

--------------------

It works fine for the first time. On the second call i have no response from server.
Newbie here. Can someone help me please?

Thanks in advance

Can you include the code for

// do http request & ...

? And what is the code if do http request fails?

Another point: you don't need

return res.json ..;

Change to

res.json...;

Its like this. Thank you. 

(can view the code here: http://www.codeshare.io/rA1w9)

var testFunc : function(stuff, callback) {

    var result = {

        error: false,

        data: ''

    };

    var post_body_xml = xmlbuilder.buildObject(post_body);

    // An object of options to indicate where to post to

    var post_options = {

        host: api.endpoint,

        path: api.path,

        port: '80',

        method: 'POST',

        headers: {

            'Content-Type': 'text/xml',

            'Content-Length': post_body_xml.length

        }

    };

    // Set up the request

    var post_req = http.request(post_options, function(res) {

        res.setEncoding('utf8');

        res.on('data', function(chunk) {

            result.data += chunk;

        });

        res.on('error', function(e) {

            console.log('problem with request: ' + e.message);

            result = {

                error: true,

                data: e.message

            };

        });

        res.on('end', function() {

   

            xmlparser.addListener('end', function(json_result) {

                result.data = json_result;

                //console.log(result);

                callback(result);

            });

            xmlparser.parseString(result.data);

            

        });

    });

    // post the data

    post_req.write(post_body_xml);

    post_req.end();

};
