This is a simple WebView running as a websocket client. Here are notes: | |
- To test, run a local socket server (ie, socket.io). Socket.io example chat app: http://socket.io/get-started/chat/ | |
- Pass the websocket URL into io.connect() method | |
- Event callbacks are registered on Ti.App.. app should fire 'app:ws:connected'. Observe console.log: "Websocket is connected" | |
- For securty purposes, use inline HTML (string below) to compile into bytecode, rather than filesystem / HTML resources. | |
- The final webview has to be painted to the screen to instantiate Webkit. Simply 1x1 pixel with offset positiong. Webview becomes a processor. | |
