vue-observables

Knockout-like functional syntax for Vue.js. Observables use all of Vue's reactivity, therefore they can trigger template updates, watchers, etc.

observable<T>(value?: T)

import { observable } from 'vue-observables'

const foo = observable(1)
console.log(foo()) // 1

foo(2)
console.log(foo()) // 2

observableArray<T>(value: T[] = T[])

Technically not needed, as Vue tracks deep reactivity for refs, but is provided for symmetry with Knockout.

import { observableArray } from 'vue-observables'

const foo = observableArray([1])
console.log(foo()) // [1]

foo().push(2)
console.log(foo()) // [1, 2]

computed(getter [, debugOptions ])

import { computed } from 'vue-observables'
// ...
const foo = computed(() => bar())

computed(options [, debugOptions ])

A computed observable.

options

function	description
read / get	getter function
write / set	(opt) setter function

Usage in templates

<script setup lang="ts">
// ....
import { observable } from 'vue-observables'

const show = observable(false)
</script>

<template>
  <Popup :show="show()" />
</template>
