TDA4VM: websocket server examble

Hi Vadivel,

We have the websocket component in the filesystem, as seen in this ticket: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1085300/tda4vm-sdk8-1-websocketd-recipe-is-failing

However, we do not maintain an example on using it, but it should be the same as you would on any other system. You can find examples online and try them out on the Linux SDK. Please let me know if you have further questions.

Hi Erick, 

I am getting following error for the code.   so, how to add websocket module? through yocto build.

Note: websocketd (daemon) - already there in the final-image

Code:

        var websocket= require('ws')

              or

       var ws= require('websocket')

Error: Cannot find module 'ws'   

     or 

Error: Cannot find module 'websocket'   

root@j7-evm:/opt/cabin# node server_new.js
internal/modules/cjs/loader.js:818
throw err;
^
