Universal cookie plugin, perfect for SSR

You can use cookie-universal to set, get and remove cookies in the browser, node, connect and express apps. cookie-universal parse cookies with the popular cookie node module.

Install

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

Usage

// server
app.get('/', (req, res) => {
  const cookies = require('cookie-universal')(req, res)
  cookies.set('cookie-name', 'cookie-value')
})

// browser, from import
import Cookie from 'cookie-universal'
const cookies = Cookie()
cookies.set('cookie-name', 'cookie-value')

// browser, from dist
// note: include dist/cookie-universal.js
const cookies = Cookie()
cookies.set('cookie-name', 'cookie-value')

ParseJSON

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


Disable globally

// server
const parseJSON = false
app.get('/', (req, res) => {
  const cookies = require('cookie-universal')(req, res, parseJSON)
})

// browser, from import
import Cookie from 'cookie-universal'
const parseJSON = false
const cookies = Cookie(false, false, parseJSON)


Disable globally on the fly

// server
app.get('/', (req, res) => {
  const cookies = require('cookie-universal')(req, res)
  cookies.parseJSON = false
})

// browser, from import
import Cookie from 'cookie-universal'
const cookies = Cookie(false, false)
cookies.parseJSON = false


Disable on a specific get request

// server
app.get('/', (req, res) => {
  const cookies = require('cookie-universal')(req, res)
  cookies.set('cookie-name', 'cookie-value')
  cookies.get('cookie-name', { parseJSON: false })
})

// browser, from import
import Cookie from 'cookie-universal'
const cookies = Cookie(false, false)
cookies.set('cookie-name', 'cookie-value')
cookies.get('cookie-name', { parseJSON: false })
