Incorrect type for ws.publish

[klavinski]

What version of Elysia is running?

1.1.12

What platform is your computer?

Darwin 24.1.0 arm64 arm

What steps can reproduce the bug?

In an Elysia.ws handler, add a response validator and use ws.publish, like this:

new Elysia()
    .ws( "/", {
        open: ws => {
            ws.publish( "channel", "hello" )
        },
        response: t.String()
    } )
    .listen( 3000 )

What is the expected behavior?

There should be no type error.

What do you see instead?

"hello" has a type error:

Argument of type string is not assignable to parameter of type { 200: string; }.

Additional information

Essentially, when response validates the type T, the type checking of data argument requires {200: T}. However, the execution expects T: if provided with a {200: T}, a validation error is thrown.

I believe a previous version had the correct type for the data argument: WS['data']['schema']['response'] instead of Route["response"].

Have you try removing the node_modules and bun.lockb and try again yet?

No.

The generated type for Eden Treaty's subscribe is also wrong. I currently use it like this:

treatyClient.websocketRoute.subscribe().subscribe( ( { data } ) => {
    const wellTypeData = data as unknown as ( typeof data )[ 200 ] )
} )
