I've found the examples provided elsewhere don't work correctly on the first request. The first request triggers .on('upgrade') registration, causing subsequent requests to succeed. But the first request hangs indefinitely.

@justin-together could you give concrete urls to the examples you are referring to?

Here you can find a Next.js recipe: https://github.com/chimurai/http-proxy-middleware/blob/master/recipes/servers.md#nextjs

Documentation to subscribe to upgrade event manually: https://github.com/chimurai/http-proxy-middleware/blob/master/README.md#external-websocket-upgrade

Happy to hear what kind of document is missing and can be improved
