Typescript for onConnect connectionParams?

[theogravity]

What's the generic to use for defining the connectionParams on context?

useServer({
  onConnect: async (ctx) => {
     // ctx.connectionParams.token is of type unknown
     const token = ctx.connectionParams.token
  }
})

There was none at the time of asking. The idea was that the server has to deal with clients that may not comply with the required connectionParams too, so I left the generic out.

However, you indeed expect most of the clients to send over the proper params, so why not have a generic! Landed in v5.6.0 (through #311). Your example becomes:

useServer<{ token: string }>(
  {
    onConnect: async (ctx) => {
      // connectionParams can be undefined because you shouldnt
      // rely on all clients on the internet to send them
      const token: string | undefined = ctx.connectionParams?.token;
    },
  },
  ...
);

Thank you!
