This is a demonstration of how we can display field event results, live, so that spectators can follow the action. We're "replaying" a competition in a loop for demo purposes. For an event in progress, an official with a phone or tablet would input the throws, and anyone watching - parents and friends at trackside, or anywhere in the world - can follow the state of the match easily.

Server.js (very basic):

Nodejs (https://nodejs.org/en/)

Node modules:

express (npm install express) // will be removed soon as no longer a requirement.

socket.io (npm install socket.io) // Handles websocket broadcasts.

forever (npm install forever) // keeps server.js running when it goes belly up

index.html:

This now does not need to be served from node server and can be loaded independantly from non-ssl servers.

examples/rawdemo.html:

Most stripped down basic client posible. Writes the raw json results from the server to the console.
