Socket support with chrome extensions

[Johnny Bx]

Hi,

I want to create a chrome extension that will expose the current tab and url opened by chrome. I should be able to query this extension from any external app (nodejs server for ex) and I expected to use socket.

The chrome extension will play the role of the server and I will send request from the external applications to get the current tab.

By checking the chrome documentation I am really confuse if I can use chrome.socket.udp or chrome.socket.tcp or even chrome.socket.tcpserver from an extension or is it limited to apps? Is websocket is supported?  

Looks like others are using socket.io (https://stackoverflow.com/questions/31061673/chrome-extension-socket-io-node-js) but this example is actually the opposite because the extension consumes data and the server is the external app.

I need a bit of guidance to take the right decision because everything I've tried so far, doesn't work. I am sure that I will be facing to other issues afterward (CORS....) but I will fix that at the right moment.

Thanks in advance.

chrome.socket.* can't be used in extension. But Native Messaging seems to work in extension.

Thanks. I will check how I can interact with native messages from an external source.
