  await import('@prefresh/core')
  hotmods({ paths: ['/components'] }, (reloads) => {
    for (const { original, previous, next, type, key } of reloads) {
      console.log('Hot reloading - path:', key, 'operation:', type)
      window.__PREFRESH__.replaceComponent(original, next, true)
      window.__PREFRESH__.replaceComponent(previous, next, true)
    }
