Instagram Gallery
Storify runs on Node.js and Express.js, therefore why not use these technologies to write an application that demonstrates how to build apps that rely on third-party APIs and HTTP requests to them?
The Instagram Gallery app will fetch story object and display title, description, and a gallery of the elements/images like this:

Require dependencies:
var express = require('express');
var superagent = require('superagent');
var consolidate = require('consolidate');
var app = express();Configure template engine:
app.engine('html', consolidate.handlebars);
app.set('view engine', 'html');
app.set('views', __dirname + '/views');Set up a static folder middleware:
app.use(express.static(__dirname + '/public'));
var user = 'azat_co';
var story_slug = 'kazan';
Paste your values, i.e., Storify API key, username and _token:
var api_key = "";
var username = "";
var _token = "";

[Sidenote]
Reading blog posts is good, but watching video courses is even better because they are more engaging.
A lot of developers complained that there is a lack of affordable quality video material on Node. It's distracting to watch to YouTube videos and insane to pay $500 for a Node video course!
Go check out Node University which has FREE video courses on Node: node.university.
