I am customizing websocket node for subscribing to multiple comma separated node. I found the source code [https://github.com/node-red/node-red/blob/master/test/nodes/core/network/22-websocket\_spec.js](https://github.com/node-red/node-red/blob/master/test/nodes/core/network/22-websocket_spec.js) but how can I modify the code for custom websocket client creation.

Using an editor ?

You found the test case file for it. The actual source for the node is here - [node-red/packages/node\_modules/@node-red/nodes/core/network/22-websocket.js at master · node-red/node-red · GitHub](https://github.com/node-red/node-red/blob/master/packages/node_modules/%40node-red/nodes/core/network/22-websocket.js)
