vue-is-defined

A Vue 3 composition API type guard utility that checks if a ref's value is defined (not null or undefined), with proper TypeScript type narrowing for safe property access.

Installation

``bash
npm install vue-is-defined
`

Usage

`ts
import { isDefined } from 'vue-is-defined'
import { ref, computed } from 'vue'

const value = ref('hello')
const defined = isDefined(value)

console.log(defined.value) // true

value.value = undefined
console.log(defined.value) // false
``
