TypeScript ESLint: "Unsafe assignment of an error typed value" when using Socket in NestJS WebSocket

[merry shale]

I'm working on a NestJS WebSocket gateway and running into a TypeScript ESLint error when trying to use the Socket type from socket.io. 😵‍💫

[upbeat leaf]

[dreamy pecan]

can u explan about this?

why did u write there?

[upbeat leaf]

it goona disable that property of eslint for that file

It’s still not fixed.
I’d like to know if there are any solutions other than disabling this rule.

I don’t understand why the original code throws an error. From what I read in the documentation, the first parameter of handleConnection should be the WebSocket instance in use.

it's just type error

variable a can't have Socket

so, plz change type

What type should I be using then?

Even if I just call a method that the client should normally have, like emit, it still throws an error.
It really seems like the issue is with the type of the client parameter.

Errors are hard aren't they?

The documentation says you can’t assign a value of type any to another value.
In my screenshot, the handleConnection function is an implementation of OnGatewayConnection.

When I looked into the OnGatewayConnection interface, I found this code:

export interface OnGatewayConnection<T = any> {
  handleConnection(client: T, ...args: any[]): any;
}

Since client is defined as a generic any by default, I thought that if I moved the Socket type from handleConnection(client: Socket) up to the class level, it would solve the problem:

export class AppGateway implements OnGatewayConnection<Socket> {}

But even after passing the generic parameter, the issue still wasn’t resolved.
Or is there something I’ve misunderstood?

now i see what you mean you ussually want to avoid this
but you can always

// @ts-ignore the line
