--- title: No Before Interactive Script Outside Document --- > Prevent usage of `next/script`'s `beforeInteractive` strategy outside of `app/layout.jsx` or `pages/_document.js`. ## Why This Error Occurred You cannot use the `next/script` component with the `beforeInteractive` strategy outside `app/layout.jsx` or `pages/_document.js`. That's because `beforeInteractive` strategy only works inside **`app/layout.jsx`** or **`pages/_document.js`** and is designed to load scripts that are needed by the entire site (i.e. the script will load when any page in the application has been loaded server-side). ## Possible Ways to Fix It ### App Router If you want a global script, and you are using the App Router, move the script inside `app/layout.jsx`. ```jsx filename="app/layout.jsx" import Script from 'next/script' export default function RootLayout({ children }) { return ( {children} ) } ``` - [App Router Script Optimization](/docs/app/building-your-application/optimizing/scripts) - [Pages Router Script Optimization](/docs/pages/building-your-application/optimizing/scripts)
