      data: { stop: "5008" },
    },
    {
      widget: "Status",
      data: { url: "https://example.com/status.txt" },
    },
    {
      widget: "Weather",
      data: { appid: "xxxxxxxxx", city: "Waterloo" },
    },
  ],
};

The config file allows you to select widgets and set the background images. The widget tag refers to the name of the function in the file and the data is passed to the widget constructor. We can include multiple instances of the same widget as well.

Widgets

Widgets are added via a single js file in /widgets in the template below:

/*
{Widget Description}
@author {author}
@version 1.0

@data
  {id} - {description}

*/

widgetDirectory.{Widget ID} = function(data){
  // 10 second loop
  // we've decided not to use this loop, we still have to define it
  this.quickloop = null;

  // 10 min loop
  this.loop = function(callback){
    $.getJSON("https://exampleurl.com?a=" + data.{id},function(value){
      //icon class from owf or font awesome fonts
      var icon = "owf owf-" + value.icon + "-d";
      //the text (usually a single or double digit number)
      var text = value.text;
      // callback to pass the information to the display
      callback(icon, text);
    });
  }
}

Unfortunately, we need to include the js file in the top of index.html right now. (see issue #1)
