Hi @wanton minnow. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

The error message you’re seeing:

Error: Failed to publish your Function. Got error: Uncaught Error: [unenv] string_decoder.StringDecoder is not implemented yet!

indicates that the Cloudflare Pages environment (with the Nitro server engine) does not support the Node.js core module string_decoder.StringDecoder via the unenv polyfill layer. Even with the nodejs_compat compatibility flag enabled, not all Node.js APIs are available or fully polyfilled in the Cloudflare Workers runtime, and string_decoder is one of those not yet implemented.

From the knowledge sources, there is no explicit workaround or fix for this specific string_decoder.StringDecoder issue. However, similar issues with missing Node.js APIs or polyfills in the Cloudflare Pages environment have been reported, especially when using dependencies that expect a full Node.js environment. The general advice is to:

  • Audit your dependencies to see if any are importing or requiring string_decoder (directly or indirectly).
  • If possible, remove or replace those dependencies with alternatives that do not require Node.js-only modules.
  • Be aware that even with nodejs_compat, some Node.js modules are not supported in Cloudflare Workers, and this is a known limitation.

If you need full Node.js compatibility, you may need to consider deploying your Nuxt 3 app to a platform that provides a true Node.js runtime, or refactor your code and dependencies to avoid unsupported modules.

#

Unfortunately, the knowledge sources do not provide a direct solution for this specific error with string_decoder.StringDecoder on Cloudflare Pages. If you have control over your dependencies, try to identify and remove the usage of this module. Otherwise, you may need to wait for Cloudflare or the unenv project to implement support for this module, or choose a different deployment target that supports it natively.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
