This app supports displaying HTML web pages using the OVE framework.


The HTML app hosts within it a number of utilities useful for another OVE app or a generic web page:

  1. Background Utility
  2. Distributed.js Library

Application State

The state of this app has a format similar to:

    "url": "http://my.domain"

The url, property is mandatory. Optionally, launchDelay and changeAt properties can be provided to control the initial delay to pre-load the contents of the web page and the precise time at which all clients will change the page they display.

Loading the App

A web page can be loaded using the OVE APIs:


curl --header "Content-Type: application/json" --request POST --data '{"app": {"url": "http://OVE_APP_HTML_HOST:PORT","states": {"load": {"url": "http://my.domain"}}}, "space": "OVE_SPACE", "h": 500, "w": 500, "y": 0, "x": 0}' http://OVE_CORE_HOST:PORT/section


curl --header "Content-Type: application/json" --request POST --data "{\"app\": {\"url\": \"http://OVE_APP_HTML_HOST:PORT\", \"states\": {\"load\": {\"url\": \"http://my.domain\"}}}, \"space\": \"OVE_SPACE\", \"h\": 500, \"w\": 500, \"y\": 0, \"x\": 0}" http://OVE_CORE_HOST:PORT/section

If the HTML app is used to display static web pages no further controlling would be required after the web page has been loaded. The app provides a controller and exposes API that can used to control interactive web pages.

Controlling the App

The controller of the app can be loaded by accessing the URL http://OVE_APP_HTML_HOST:PORT/control.html?oveSectionId=SECTION_ID.

The app’s API also exposes a refresh operation. This operation can be executed on an individual web page or across all web pages.

To refresh a web page that is already loaded, using OVE APIs:

curl  --request POST http://OVE_APP_HTML_HOST:PORT/operation/refresh
