cookie-universal-nuxt

Universal cookie plugin for Nuxt, perfect for SSR

You can use cookie-universal-nuxt to set, get and remove cookies in both client and server side nuxt apps. cookie-universal-nuxt parse cookies with the popular cookie node module.

Install

yarn: yarn add cookie-universal-nuxt
npm: npm i --save cookie-universal-nuxt

Add cookie-universal-nuxt to nuxt.config.js:

{
  modules: [
    // Simple usage
    'cookie-universal-nuxt',

    // With options
    ['cookie-universal-nuxt', { alias: 'cookiz' }],
 ]
}

ParseJSON

By default cookie-universal will try to parse to JSON, however you can disable this functionality in several ways:

Disable globally

Disable from the plugin options:

{
  modules: [
    ['cookie-universal-nuxt', { parseJSON: false }],
 ]
}

Disable globally on the fly

// nuxt middleware
export default ({ app }) => {
  app.$cookies.parseJSON = false
}

// client
this.$cookies.parseJSON = false

Disable on a specific get request

// nuxt middleware
export default ({ app }) => {
  app.$cookies.get('cookie-name', { parseJSON: false })
}

// client
this.$cookies.get('cookie-name', { parseJSON: false })
