What is the documentation issue?

https://nextjs.org/docs/pages/api-reference/edge According to the Edge Runtime documentation, Buffer is not listed in the supported APIs. However, based on our testing, Buffer appears to　be supported and works without errors.

Is there any context that might help us understand?

I'm using Next.js v15.x and Pages Router.

I tried to implement Content Security Policy (CSP). So I added the nonce by following the document: https://nextjs.org/docs/15/pages/guides/content-security-policy#nonces

In the sample code, it uses Buffer.

const nonce = Buffer.from(crypto.randomUUID()).toString('base64')

But in the document about middleware, "Middleware defaults to using the Edge runtime". https://nextjs.org/docs/15/app/api-reference/file-conventions/middleware#runtime

And I couldn't find Buffer in the supported APIs https://nextjs.org/docs/pages/api-reference/edge

However, as long as I deployed and tested, it worked without errors. Does it mean I can use Buffer in Edge Runtime?

Does the docs page already exist? Please link to it.

extent analysis

TL;DR

The issue can be resolved by verifying the support of Buffer in Edge Runtime through official documentation or testing, as it appears to work despite not being listed in the supported APIs.

Guidance

  • Review the Edge Runtime documentation to confirm if Buffer is supported, as the current documentation does not explicitly list it.
  • Test the usage of Buffer in a controlled environment to verify its functionality and potential errors.
  • Consider reaching out to the Next.js community or support for clarification on the support of Buffer in Edge Runtime.
  • If Buffer is not supported, explore alternative APIs or methods for achieving the desired functionality.

Example

// Alternative to Buffer for generating a nonce
const nonce = crypto.randomUUID();

Notes

The solution assumes that the Edge Runtime documentation is up-to-date and accurate. However, the fact that Buffer works despite not being listed suggests a potential discrepancy between the documentation and the actual implementation.

Recommendation

Apply workaround: Use Buffer with caution and thorough testing, as it appears to work despite not being explicitly supported in the Edge Runtime documentation. This approach allows for the continued use of Buffer while acknowledging the potential for future changes or issues.
