The echo server will show number of types received (5 types for 5 characters in this case) and sent back.įinally, we can close the echo server by typing: sock.close() Once the connection is established, we can communicate with the echo server through the proxy websocket server. If successful, the websockify console window will show messages like:

The second parameter in the constructor () are protocols required to be supported by the client. This will create a websocket client and connect to the proxy server. Type the following command: var sock=new WebSocket("ws://localhost:27016", ) To connect to the proxy server, I use Firefox console. Next, run the echo server (the compile executable you get in Step 1). the first is the address/port for the proxy websocket server, the second is the address/port for the ‘target’ tcp/ip echo server. Now we are ready to run Websockify.js.įirst, open a console window and get to the directory “websockify-master\other\js\”, then type: node websockify.js localhost:27016 localhost:27015

Add NODE_PATH to your PATH variable by attaching %NODE_PATH% to the end of “PATH”.

Create a new system variable named “NODE_PATH”, and set its value to c:\\Users\%your account name%\AppData\Roaming\npm\npm_modules.

Go to: Control Panel\System and Security\System.

That’s because the environment variable is not set yet. Now, if you run Websockify.js, it most likely will complain about not finding files for optimist etc. You should be able to find them in the folder (assume your windows is installed on drive C): c:\\Users\%your account name%\AppData\Roaming\npm\npm_modules

#NODE JS WINDOWS MODULE WEBSOCKET INSTALL#

Replace ‘ modulename‘ with optimist, policyfile and ws (i.e., run npm install three times) to install all three modules. The command to install modules is as follows: npm install -g modulename It will show the installed version of Node on your machine. Once Node.js is installed, first lets check the installation is successful by opening a console window and type: Furthermore, Websockify requires a couple modules (optimist, policyfile, ws) not installed by default. In order to run Node version Websockify, we need Node.js to be installed first. Instead, it’s easier to work with Node version of Websockify (websockify-master\other\js\websockify.js), and that’s what we are going to do.

I have wasted a lot of time went down this path.

You can find posts about how to compile Websockify as Windows executable and even make it into a service.

Next, download Websockify zip file and unzip it on your machine. This echo server listens to port 27015 and will send whatever message it received back to the client. To setup the demo, an Winsock echo server will be used.

So I decided to write about what I have learned with a demo. However, it took me a while to figure out how exactly to use it in Windows. After a little search, Websockify seems to be THE way to do it. Some middle-ware is required to ‘bridge’ the two. Since TCP socket and WebSocket use different handshake, they cannot communicate directly. Recently, I ran into the problem of how to communicate between a TCP/IP socket server and a WebSocket client.
