Have we lost WebIDE with TCP/IP or is there a workaroud?

I often used the LINUX board and connect via WebIDE and TCP/IP for source testing. Looks like this is not possible any more because SETTINGS->COMMUNICATION does not offer TCP/IP input. I still can build a LINUX board and launch it with parameter --telnet like this:
```
bin/espruino --telnet
```
Any hints what I miss or what workaround is available to get this working again?

I'm afraid it's gone because Google are in the process of shutting down the Chrome web app, so we're left with espruino.com/ide which doesn't support telnet directly as far as I know.

I guess the only real option would be to make the Linux build capable of starting an HTTP server with websockets - there is a fragment of JS code that does this already (below), but because it's doing it in JS isn't not as flexible as something built in at a lower level:

function onPageRequest(req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.end(`<html>
<body style="margin:0px"> 
<iframe id="ideframe" src="https://www.espruino.com/ide/" style="width:100%;height:100%;border:0px;"></iframe>
<script src="https://www.espruino.com/ide/embed.js"></script>
<script>
  var ws = new WebSocket("ws://" + location.host + "/ws", "serial");
  var Espruino = EspruinoIDE(document.getElementById('ideframe'));
  Espruino.onports = function() {
    return [{path:'local', description:'Local Device', type : "net"}];
  };
  Espruino.onready = function(data) { Espruino.connect("local");};
  Espruino.onwrite = function(data) { ws.send(data); }
  ws.onmessage = function (event) { Espruino.received(event.data); };
  ws.onclose = function (event) { Espruino.disconnect(); };
</script>
</body>
</html>`);
}

/* Hack to ensure that `reset` won't cause us problems */
global.reset = function() {
  console.log("Ignoring reset() request");
};

var server = require('ws').createServer(onPageRequest);
server.listen(80);
server.on("websocket", function(ws) {
  ws.on('message',function(msg) { LoopbackA.write(msg); });
  LoopbackA.on('data',function(msg) { ws.send(msg); }); 
  ws.on('close', function() { 
    LoopbackA.removeAllListeners();
    USB.setConsole(); 
  });
  LoopbackB.setConsole();
});

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
