How to install the cookie banner on version Next.js 13 and above?

Last updated on May 20, 2026

To install the cookie banner, you can follow either of the two ways to add the third-party script to your Next.js project:

  1. Navigate to app>layout.js and add the following steps, or
  2. Navigate to the pages>_app.js and add the following steps.

Step 1: Import the next/script component.

To load CookieYes in your Next.js application, add the following import statement:

import Script from 'next/script';

Step 2: Add CookieYes script code.

To enable CookieYes on your website, add the following CookieYes script code:

<Script
  src={`https://cdn-cookieyes.com/client_data/XXXXXXXX/script.js`}>
  </Script>
Note:

You need to replace ‘XXXXXXXX’ with your CookieYes website key.

You can copy your installation code from Site Settings from the top navigation panel of your CookieYes dashboard.

Step 3: Add the strategy property beforeInteractive.

To ensure the script loads and executes without delaying the rendering of the page, add the following strategy below the CookieYes script code.

strategy="beforeInteractive"

After completing the above steps, the file should be like this:

Note:

CookieYes does not support the crossorigin attribute, as it may cause caching issues when used with the CookieYes script. If your website automatically adds this attribute when using the Next.js script component, we recommend using the standard <script> tag provided by CookieYes (installation script) instead to ensure that updates are applied immediately.
