useCookies

wrapper for universal-cookie.

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>

SSR support (Nuxt plugin example) 

// universal-cookies.js
import { createCookies } from '@vueuse/integrations/useCookies'

let useUniversalCookies

const cookiesPlugin = ({ req }) => {
  useUniversalCookies = createCookies(req)
}

export default cookiesPlugin

export { useUniversalCookies } // now import and call useUniversalCookies instead of useCookies

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 getgetAll methods.
  • autoUpdateDependencies (boolean = false): automatically add cookie names ever provided to getmethod. 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 useCookiesfunction with provided universal-cookie instance
