ssap-web

A hacky implementation of webOS remote control API on the web.

How it works

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.

Limitations

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

Demo app in index.html can be used to preview current screen contents and perform basic remote control (arrow keys, enter = OK, escape = Back, home = Home)
