Reactively omit fields from a reactive object.

Usage

Basic Usage

import { reactiveOmit } from '@vueuse/core'

const obj = reactive({
  x: 0,
  y: 0,
  elementX: 0,
  elementY: 0,
})

const picked = reactiveOmit(obj, 'x', 'elementX') // { y: number, elementY: number }

Predicate Usage

import { reactiveOmit } from '@vueuse/core'

const obj = reactive({
  bar: 'bar',
  baz: 'should be omit',
  foo: 'foo2',
  qux: true,
})

const picked = reactiveOmit(obj, (value, key) => key === 'baz' || value === true)
// { bar: string, foo: string }

Scenarios

Selectively passing props to child

<script setup>
import { reactiveOmit } from '@vueuse/core'

const props = defineProps({
  value: {
    default: 'value',
  },
  color: {
    type: String,
  },
  font: {
    type: String,
  }
})

const childProps = reactiveOmit(props, 'value')
</script>

<template>
  <div>
    <!-- only passes "color" and "font" props to child -->
    <ChildComp v-bind="childProps" />
  </div>
</template>

Type Declarations

export type ReactiveOmitPredicate<T> = (
  value: T[keyof T],
  key: keyof T,
) => boolean
export declare function reactiveOmit<T extends object, K extends keyof T>(
  obj: T,
  ...keys: (K | K[])[]
): Omit<T, K>
export declare function reactiveOmit<T extends object>(
  obj: T,
  predicate: ReactiveOmitPredicate<T>,
): Partial<T>
