Your server code seems fine. Though you should check if you can connect to its socket via another client.

Anyway try this for react native code.

Import by:

import io from 'socket.io-client/socket.io'

In your component do:

componentDidMount () {
    const socket = io(YOURURL, {
      transports: ['websocket']
    })

    socket.on('connect', () => {
      console.log("socket connected")
      socket.emit('YOUR EVENT TO SERVER', {})
      socket.on('EVENT YOU WANNA LISTEN', (r) => {
      })
    })

    socket.on('connect_error', (err) => {
      console.log(err)
    })

    socket.on('disconnect', () => {
      console.log("Disconnected Socket!")
    })
  }
