nookies 🍪 🍪 🍪

A collection of cookie helpers for Next.js

Demo

Try a demo of the example code below here:

Demo on CodeSandbox

getServerSideProps cookies (SSR + Client)

import { parseCookies, setCookie, destroyCookie } from 'nookies'

export default function Me({ cookies }) {
  return (
    <div>
      My profile. Cookies:
      <ul>
        {cookies &&
          Object.entries(cookies).map(([name, value]) => (
            <li>
              {name}: {value}
            </li>
          ))}
      </ul>
    </div>
  )
}

export async function getServerSideProps({ ctx }) {
  // Parse
  parseCookies(ctx)

  // Set
  setCookie(ctx, 'fromGetServerSideProps', 'value', {
    maxAge: 30 * 24 * 60 * 60,
    path: '/',
  })

  // Destroy
  // destroyCookie(ctx, 'cookieName')

  return { cookies };
};

OR

import nookies from 'nookies'

export default function Me () {
  return <div>My profile</div>
}

export async function getServerSideProps({ ctx }) {
  // Parse
  nookies.get(ctx)

  // Set
  nookies.set(ctx, 'fromGetInitialProps', 'value', {
    maxAge: 30 * 24 * 60 * 60,
    path: '/',
  })

  // Destroy
  // nookies.destroy(ctx, 'cookieName')

  return { cookies };
}

Client-only Cookies

import { parseCookies, setCookie, destroyCookie } from 'nookies'

function handleClick() {
  // Simply omit context parameter.
  // Parse
  const cookies = parseCookies()
  console.log({ cookies })

  // Set
  setCookie(null, 'fromClient', 'value', {
    maxAge: 30 * 24 * 60 * 60,
    path: '/',
  })

  // Destroy
  // destroyCookie(null, 'cookieName')
}

export default function Me () {
  return <button onClick={handleClick}>Set Cookie</button>
}

Reference

For client side usage, omit the ctx parameter. You can do so by setting it to an empty object ({}).

parseCookies(ctx, options) or cookies.get(ctx, options)

• ctx: Next.js context
• options:
  • decode: a custom resolver function (default: decodeURIComponent)

setCookie(ctx, name, value, options) or cookies.set(ctx, name, value, options)

• ctx: (Next.js context)
• name: cookie name
• value: cookie value
• options:
  • domain
  • encode
  • expires
  • httpOnly
  • maxAge
  • path
  • sameSite
  • secure

destroyCookie(ctx, name, options) or cookies.destroy(ctx, 'token', options)

• ctx: (Next.js context)
• name: cookie name
• options:
  • domain
  • path
