attach is not a function

[Kikketer]

Pretty simple one to repeat, both the docs and the example cause the same error:

TypeError: sockjs_echo.attach is not a function

Using the example code:

const http = require('http')
const sockjs = require('sockjs')
const node_static = require('node-static')

// 1. Echo sockjs server
const sockjs_opts = {
  prefix: '/echo'
}

const sockjs_echo = sockjs.createServer(sockjs_opts)
sockjs_echo.on('connection', function(conn) {
  conn.on('data', function(message) {
    conn.write(message)
  })
})

// 2. Static files server
const static_directory = new node_static.Server(__dirname)

// 3. Usual http stuff
const server = http.createServer()
server.addListener('request', function(req, res) {
  static_directory.serve(req, res)
})
server.addListener('upgrade', function(req, res) {
  res.end()
})

// Dead here
sockjs_echo.attach(server)

console.log(' [*] Listening on 0.0.0.0:9999')
server.listen(9999, '0.0.0.0')

Has there been a major version update that breaks the documentation?

node -v
v8.12.0

There is a big warning on the README in master:

⚠️️ ATTENTION This is pre-release documentation. The documentation for the latest stable release is at: https://github.com/sockjs/sockjs-node/tree/v0.3.19 ️⚠️
