TS2304: Cannot find name 'WebSocket'.

[JimmyBjorklund]

node_modules/mqtt/build/lib/shared.d.ts:10:14 - error TS2304: Cannot find name 'WebSocket'.

This line seams to be missing
import type { WebSocket } from 'ws';

This issue was introduced in 5.3.0, its not present in 5.2.2

@JimmyBjorklund That's strange as I should get the same error on compilation too. That websocket is not the ws Websocket, it's https://developer.mozilla.org/en-US/docs/Web/API/WebSocket and them are really different.

Maybe some types are missing ?

try add: "skipLibCheck": true to your tsconfig

Having exactly the same issue (link).

"skipLibCheck": true suppresses the issue but not acceptable because it reduce the type-system accuracy

[robertsLando]

@Koenkk Do you guys have a suggestion about how I could explicitly make it to return window.Websocket type instead ws Websocket?

5.3.1 is coming, sorry for the inconvenience...
