`pool.ts` where `_WebSocket` and `useWebSocketImplementation` can be found:
Morning folks. Quick one, I'm working (well, actually, talking my mouth off and getting in the way of their good work 🤣) with Keyoxide folks on their Matrix channel. They are implementing Nostr support and having an interesting issue with nostr-tools.
Apparently
```
import { WebSocket } from 'ws'
useWebSocketImplementation(WebSocket)
```
Is not setting the WS in their environment. Bizarrely, manually setting the variable works.
```
pool._WebSocket = WebSocket
```
See: https://code.jaenis.ch/gists/nostr-tools-websocket-closure-leak/src/branch/main/nostr.js#L28
If you comment line 28 things break.
The code is runnable (`npm i && npm run test`).
I'm a bit clueless when it comes to TypeScript, but it feels like this was meant be somewhat of a "private" global variable. Somehow `useWebSocketImplementation` is not working in this example. After calling `useWebSocketImplementation` WebSocket is still undefined.
Anyone more familiar with TypeScript and Nostr tools can have a look?
