Self-signed certs with secure WebSockets in Node.js

First generate your self-signed certs:

Then create your httpsServer from an express app using node’s built-in https server:

Then setup your websocket server (ironically this will use the same port as the http server, I didn’t know this but I guess protocols can share ports? — this had me going for awhile).

Now browse to server and accept the self-signed cert in Chrome. Then websockets should now work isnide the browser.

Open a chrome devtools console and type:
