How to access server context / global state from a websocket handler?

I have this simple websocket handler defined at

server/routes/websocket.ts

server/routes/websocket.ts

, I've already enabled the

nitro.experimental.websocket

nitro.experimental.websocket

flag in

nuxt.config.ts

nuxt.config.ts

and it works fine.

export default defineWebSocketHandler({
  open(peer) {
    console.log('peer connected')
  },
  message(peer, message) {
    const text = message.text()

    if (text === 'ping') {
      peer.send('pong');
    }
  },
})

export default defineWebSocketHandler({
  open(peer) {
    console.log('peer connected')
  },
  message(peer, message) {
    const text = message.text()

    if (text === 'ping') {
      peer.send('pong');
    }
  },
})

However, it doesn't seem there's a way to access a global state or server context like it's possible on event handlers:

export default defineEventHandler(event => {
  // in event handlers context is accessible at `event.context`
})

export default defineEventHandler(event => {
  // in event handlers context is accessible at `event.context`
})

I need this in order to initialize and access global services like database connections etc.
