Link to the code that reproduces this issue

https://codesandbox.io/p/devbox/quizzical-maxwell-cdww8j

To Reproduce

  1. pnpm install
  2. pnpm dev (webpack)
  3. Visit localhost:3000
  4. Observe; console logs the randomUUID (when a client component is first ran on the server), but fails client-side
  5. Add the node: protocol to crypto
  6. Observe; console does not log the randomUUID (throws an error) and so does client-side

Current vs. Expected behavior

For client components, it seems that crypto is only pollyfilled server-side (where client components are first render on) and only with the non-protocol import.

importServer-sideClient-side
crypto✅❌
node:crypto❌❌

Shouldn't crypto be pollyfilled consistently? So node:crypto (with protocol) is also polyfilled server-side and preferably also client-side for both.

extent analysis

TL;DR

The issue can be resolved by consistently polyfilling the crypto module for both server-side and client-side rendering, including when using the node:crypto protocol.

Guidance

  • Verify that the crypto module is properly polyfilled in the Next.js configuration for both server-side and client-side rendering.
  • Check the Webpack configuration to ensure that the crypto module is not being excluded or overridden for client-side rendering.
  • Test using the crypto module without the node: protocol to see if the issue persists, and consider using a consistent import method throughout the application.
  • Review the Next.js documentation and Webpack configuration to ensure that the crypto module is properly handled for both server-side and client-side rendering.

Example

No explicit code example is provided as the issue is related to configuration and polyfilling, but ensuring consistent import and configuration of the crypto module is crucial.

Notes

The issue seems to be specific to the Next.js and Webpack configuration, and resolving it may require adjustments to the project's setup and dependencies.

Recommendation

Apply a workaround by consistently polyfilling the crypto module for both server-side and client-side rendering, as this seems to be the most straightforward way to resolve the issue without upgrading or changing the underlying dependencies.
