How to Connect to a TCP Socket from a Browser Using JavaScript in Chrome\'s Experimental Feature?

Connecting to TCP Socket from Browser Using JavaScript

While you seek to establish a two-way communication between a browser's JavaScript and a TCP socket hosted by a .NET application, the current landscape of web technologies poses challenges.

As of now, popular browsers lack a standardized socket API for JavaScript. However, there are promising developments underway. The Raw Sockets API, which would allow direct socket manipulation, is currently in its draft stage.

Although the Raw Sockets API remains in flux, experimental support for TCP sockets has emerged in the Chrome browser. To leverage these features, enable the "experimental" flag in your Chrome extension's manifest. The following code snippet illustrates how to create and connect a TCP socket:

<code class="javascript">chrome.experimental.socket.create('tcp', '127.0.0.1', 8080, function(socketInfo) {
  chrome.experimental.socket.connect(socketInfo.socketId, function (result) {
    if (result) {
      chrome.experimental.socket.write(socketInfo.socketId, "Hello, world!");
    }
  });
});</code>
