A hacky implementation of webOS remote control API on the web.
By default a server implementing SSAP on webOS prevents web origins from
accessing its websocket. However there are exceptions to allow communication
from chrome extensions and file:// origins. Both file:// and data:
origins present themselves to remote server as Origin: null. We use that to
allow http-based origin to communicate with SSAP server using a hidden iframe
with src="data:..." communicating back and forth with the main http://
frame. This is implemented in wsproxy.js.
Currently this client can't be effectively used on https:// origins due to
mixed content security policies. Alternatively, user can be requested to
manually approve self-signed certificate used for wss://:3001 server exposed
by webOS.
Demo app in index.html can be used to preview current screen contents, save them when stopped and
perform basic remote control (arrow keys, enter = OK, escape = Back, home = Home, end = Exit)
