Wrapper for universal-cookie.

TIP

When using with Nuxt 3, this functions will NOT be auto imported in favor of Nuxt's built-in useCookie(). Use explicit import if you want to use the function from VueUse.

Available in the @vueuse/integrations add-on.

Install

npm i universal-cookie

Usage

Common usage

<template>
  <div>
    <strong>locale</strong>: {{ cookies.get('locale') }}
    <hr>
    <pre>{{ cookies.getAll() }}</pre>
    <button @click="cookies.set('locale', 'ru-RU')">Russian</button>
    <button @click="cookies.set('locale', 'en-US')">English</button>
  </div>
</template>

<script>
  import { defineComponent } from 'vue'
  import { useCookies } from '@vueuse/integrations/useCookies'

  export default defineComponent({
    setup() {
      const cookies = useCookies(['locale'])
      return {
        cookies,
      }
    },
  })
</script>

Options

Access and modify cookies using vue composition-api.

By default, you should use it inside setup(), but this function also works anywhere else.

const { get, getAll, set, remove, addChangeListener, removeChangeListener } = useCookies(['cookie-name'], { doNotParse: false, autoUpdateDependencies: false })

`dependencies` (optional)

Let you optionally specify a list of cookie names your component depend on or that should trigger a re-render. If unspecified, it will render on every cookie change.

`options` (optional)

doNotParse (boolean = false): do not convert the cookie into an object no matter what. Passed as default value to get getAll methods.
autoUpdateDependencies (boolean = false): automatically add cookie names ever provided to get method. If true then you don't need to care about provided dependencies.

`cookies` (optional)

Let you provide a universal-cookie instance (creates a new instance by default)

Info about methods available in the universal-cookie api docs

`createCookies([req])`

Create a universal-cookie instance using request (default is window.document.cookie) and returns useCookies function with provided universal-cookie instance

req (object): Node's http.IncomingMessage request object
