How to extend Client and Socket types in [email protected] and [email protected]

[ehsanshekari]

I have a Node.js Server with Typescript and now I want to update the socket.io depencency to 4.2.0.
I need to extend Client and Socket objects. Previously, in [email protected] I could do something like below:

export interface CustomClient extends Client {
  customField: string;
}

export interface CustomSocket extends Socket {
  client: CustomClient;
}

How can I achieve the same thing with [email protected]?

On Socket there is a data field which is any typed. So you can put any additional data there
