Maxsus Renderer API ​

createRenderer() ​

Maxsus renderer yaratadi. Platformaga xos tugun yaratish va manipulyatsiya qilish API'larini taqdim etish orqali, Vue'ning asosiy runtime'idan DOM bo'lmagan muhitlarni nishonlash uchun foydalanish mumkin.

  js

  import { createRenderer } from '@vue/runtime-core'
  
  const { render, createApp } = createRenderer({
    patchProp,
    insert,
    remove,
    createElement
    // ...
  })
  
  // `render` - bu past darajali API
  // `createApp` - ilova instansiyasini qaytaradi
  export { render, createApp }
  
  // Vue core API'larini qayta eksport qilish
  export * from '@vue/runtime-core'

  Vue'ning o'zining @vue/runtime-dom xuddi shu API yordamida amalga oshirilgan. Soddaroq amalga oshirish uchun, Vue'ning o'zining unit testlari uchun maxfiy paket bo'lgan @vue/runtime-testni tekshiring.
