Problem WebSocket about core

[javruben]

Could you paste the full code of your plugin (first to last line)?

Thanks.

I wrote a plugin (and put it in ~/.c9/plugin/plugin-name) with following code:

var WebSocket = require('ws')
, ws = new WebSocket('ws://mylocalipaddress:8090/');
ws.on('open', function() {
ws.send('something');
});
ws.on('message', function(message) {
console.log('received: %s', message);
});
On localhost I have a server listening on port 8090

var WebSocketServer = require('ws').Server
, wss = new WebSocketServer({port: 8090});
wss.on('connection', function(ws) {
ws.on('message', function(message) {
console.log('received: %s', message);
});
ws.send('something');
});
When I try to load the IDE at

http://localhost:8186/ide.html?sdk=1?debug=2

It loads only IDE but not the plugin and my server doesn't receive any data.

If I try the same code in a client loaded in a different container it works perfectly.

Thanks

The plugin looks good, although I don't fully understand why you set an outside IP address in your plugin.

It loads only IDE but not the plugin and my server doesn't receive any data.

How do you know the plugin isn't loaded? Could you test by setting a console.log in your load() function?

If you check the network tab of the browser's console. Do you see the websocket trying to connect?

I have c9 on a container and a WebSocket server in a different docker
container. I suppose that plugin isn't loaded because in firebug I can't
find trace about console.log (when I added it) and also alert messages
aren't displayed at all. Likely it found some error and blocks js
execution... I will try to re-implement the scenario and check the network
tab.

Nope. In the network tab my websocket is absent...

I've checked package.json file. Should I add something to it?

I tried to use other "common node.js API" such as path or querystring (that have slightly different sintax) that I've seen in the documentation and they work perfectly. The problem is with "ws"

[alessioguglielmo]

Worked around the problem using different way, passing data through fs, although the original problem I have quoted persists.
