  path: '/status'
})

const app = new Engine()

// registers status monitor's middleware
app.use(statusMonitor.middleware)

app.use(({ req, res, rawRes }) => {
  // registers status monitor's page route, defaults to `/status`
  if (req.path === statusMonitor.path) {
    return statusMonitor.page({ rawRes })
  }
  res.end('Hello world')
})

app.run(3000, () => {
