useVModel

Shorthand for v-model binding, props + emit -> ref

Usage 

import { useVModel } from '@vueuse/core'

export default {
  setup(props, { emit }) {
    const data = useVModel(props, 'data', emit)

    console.log(data.value) // props.data
    data.value = 'foo' // emit('update:data', 'foo')
  },
}

Type Declarations 

export interface VModelOptions {
  /**
   * When passive is set to `true`, it will use `watch` to sync with props and ref.
   * Instead of relying on the `v-model` or `.sync` to work.
   *
   * @default false
   */
  passive?: boolean
  /**
   * When eventName is set, it's value will be used to overwrite the emit event name.
   *
   * @default undefined
   */
  eventName?: string
  /**
   * Attempting to check for changes of properties in a deeply nested object or array.
   *
   * @default false
   */
  deep?: boolean
}
