Write json file to Firebase with Node.js?

I have a third party API that I need to call every 5 seconds. I get JSON as response, and I’d like to write the JSON content to a Firebase node using Node.js. Based on Firebase examples I could import data with this code:

var usersRef = ref.child("users");
  alanisawesome: {
    date_of_birth: "June 23, 1912",
    full_name: "Alan Turing"
  gracehop: {
    date_of_birth: "December 9, 1906",
    full_name: "Grace Hopper"

Curl examples worked too. But what I really wanted to do is to import a third party API response directly to my Firebase database using the API endpoint. How can i do it with Node.js?

Logical display of dynamic data in 3d HTMl5

I cant reveal my project details here. So I am taking an example of Electrical circuit.

Suppose we have 10 lights at home and there is a centrepoint from where the electricity flows to the lights when switched on. I want to draw a logical view that at a given time, from the centrepoint, to what lights the electricity is flowing.

This representation should be in 3d View. Imagine, I have been provided with a unique symbol for centrepoint and switch.

My thought process towards this is generate a json data from my application and feed this data to HTML5 which can render the json data into 3D representation.

But my query is, the data I have is quiet complex. Say, centrepoint is connected to many subnets and set of lights are connected to each of the subnet and at a given point, what subnet is connected to centrepoint and what lights are getting electricity is connect to the particular subnet. I should show neither the subnet nor the lights which is not getting the electricity (assuming, electricity will flow to subnet when atleast one light is glowing from that subnet)

How can I render this dynamic data in HTML5 in 3d?

Kindly please point me to the example projects in github.com or direct me right tutorial.

If HTML5 is not the right choice, Kindly please direct me to the right technology that I can use to do this?

Convert Json parsed date to fit html5 input date

I am using Knockout to make a nice looking Gui like so


   viewModel = {
        lookupCollection: ko.observableArray()

    $(document).ready(function () {
            type: "GET",
            url:  "@Url.Action("GetView", "FakturaOmfangs", new {area = "" , id = ViewBag.id})",
        }).done(function (data) {
            $(data).each(function (index, element) {
                var mappedItem =
                        FakturaId: ko.observable(element.FakturaId),
                        FakturaProdukterId: ko.observable(element.FakturaProdukterId),
                        Beskrivelse: ko.observable(element.Beskrivelse),
                        Periode: ko.observable(element.Periode),
                        EndDate: ko.observable(element.EndDate),
                        procent: ko.observable(element.procent),
                        Rabat: ko.observable(element.Rabat),
                        Pris: ko.observable(element.Pris),
                        Ialt: ko.observable(element.Ialt),
                        Value: ko.observable(element.Value),
                        Mode: ko.observable("display")

the EndDate is a Datetime? parsed from controller like this

  return Json(list, JsonRequestBehavior.AllowGet);

This is my input where i would like to put the Date into, so i can edit it.

<td><input class="form-control" type="date" data-bind="value: EndDate" /></td>

How do i format the date to the correct format? so that i can use it in input type=Date ?

jQuery-Trying to emulate a simple Facebook info and feed page through Facebook Graph API

Im trying to emulate a simple page which includes facebook info like username, email etc. I’m not able to obtain the user’s posts from the json received. Tried various methods like making the feed a different function but all failed. Please help.

  function getInfo() {

    $.ajax('https://graph.facebook.com/me?access_token=' + fbtoken, {

You can insert your token in the fbToken variable using Graph API Explorer in Tools And Support. I think i'm making a mistake in retrieving the data part as it is an object-of-array but i'm having a hard time figuring out how to do it right.
