What are the steps to turn off ASO (Automatic Static Optimization) in Next.js?

In my Next.js application, I am looking to generate a unique CSP (Content Security Policy) nonce for inline scripts on a per-request basis.

To implement this, I plan to create a nonce within my `middleware.ts` file and include it in the request headers. This nonce can then be accessed by my custom `Document` component's `getInitialProps` method, which receives a context object containing properties like `req` (the incoming request).

However, I have noticed that some pages do not have a request available in the `ctx` argument passed to the `Document.getInitialProps` method. According to the [Next.js documentation](https://nextjs.org/docs/pages/building-your-application/rendering/automatic-static-optimization):

"ctx.req will be undefined for pages that are prerendered"

Is there a way to completely disable prerendering in Next.js so that all pages are consistently server-side rendered, ensuring reliable access to the request in a custom `Document` component?

Answer №1

There isn't a specific setting to enable or disable ASO in Next.js. This is likely because ASO is considered a core feature of Next.js and typically it's not recommended to opt out of this behavior for the entire application.

However, if you do need to disable ASO for your entire application, you can achieve this by creating a custom App component and implementing a "no-op" function for getInitialProps.

Keep in mind that disabling ASO will result in all pages being re-rendered on every request, which could have an impact on user experience, loading times, etc.

// _app.ts
import App from 'next/app';

export default function CustomApp() {
  // ...
}

CustomApp.getInitialProps = async (appContext) => {
  const appProps = await App.getInitialProps(appContext);
  return { ...appProps };
};
