There is probably nothing more common in the world of programming than the time honored tradition of "Hello World" examples, using the simplest possible problem to introduce someone to a new language, library, or tool.
While neither "hello" nor "world", appears anywhere in the ipify example element (https://github.com/CloudElementsOpenLabs/elements/tree/master/ipify) from our elements GitHub repository, nonetheless, it serves the same purpose by being the simplest possible (if you come up with a simpler one, please let me know).
Since elements are essentially adapters for existing APIs, this one needed a similarly minimalist API. ipify is about as simple as they come. A single endpoint that needs no authentication and just a single query parameter. This gives us an opportunity to build the perfect example of what is essential to building a new element in Cloud Elements.
