Fortumo Itrator Task

Simple iterator which polls a number of external services and if a certain criterion is met, redirects the user elsewhere.

---

Introduction

From the user's perspective, the experience is as follows:

• user arrives to the site,
• clicks a button,
• sees a loader,
• and is redirected to another page.

From the technical perspective, the flow follows a similar pattern:

• user arrives to the site,
• front end makes a request to the first service,
• the first service responds with the url of the second service and instructs to make an XHR request, 4. front end makes a request to the second service,
• 3-4 are repeated n times
• the (n+1)th service responds with the next url and instructs to redirect the user to the page

Implementation

As the idea is simple i preferd not using any MVC frameworks all done this plain javascript. i created 4 service json files in this formate as provided in spec and i added small fields for data visualization:-

{
	"id":" ",
    "activity": "xhr",
    "activity_url": "Url for next services",
    "name":"Name of service",
    "description":"service description",
    "img":"service image"

}

and the last service json format, which is responsible for redirecting after service end, like this provides also on spec:-

{
	"id":" ",
    "activity": "redirect",
    "activity_url": "http://example.com/landing_page"
}

I host this service on cloud site. i using simple ajax calling which it will recursively and automatically call the next servive until redirecting
