Hello World : first reThink application

This example is a simple application that aims to illustrate the basics steps on how to use Hyperties.

Prerequisite

This application uses the Hello World Hyperties, that have to be already deployed in a catalogue. In this case we are using the catalogue of hybroker.rethink.ptinovacao.pt domain, and the Hyperties we use in this App are HelloWorldReporter and HelloWorldObserver. Thus the Catalogue URLs for these Hyperties are:

https://catalogue.hybroker.rethink.ptinovacao.pt/.well-known/hyperty/HelloWorldReporter
https://catalogue.hybroker.rethink.ptinovacao.pt/.well-known/hyperty/HelloWorldObserver

For the Web application HelloWorld you just need a web server e.g. you can use NodeJS http-server:

Install with npm:

npm install http-server -g

execute:

http-server

This example is written in ECMA5 and does not need any transformation to run on a browser.

Functions

This Example will show you:

• How the Runtime is loaded (which is also published on hybroker.rethink.ptinovacao.pt catalogue server)
• How Hyperties are instantiated and associated with an identity selected by the user
• How to synchronise a simple Hello data object between the HelloWorldReporter Hyperty and the HelloWorldObserver Hyperty.

Files included:

• index.html :main page
• helloWorldHypertyClient.js : javascript that manage the Hyperties in the application
