Are there any decent logging libraries that work with the edge runtime?

I've had a hard time adding some form of logging to Next.js middleware when self-hosting. I've tried to use winston and pino since those are the most popular options, but both of them have issued when used in middleware, or any route that uses the edge runtime. (winston uses process.nextTick internally, which is not supported, and pino transports don't seem to work at all: TypeError: pino__WEBPACK_IMPORTED_MODULE_0__.pino.transport is not a function)

Are there any decent logging libraries that work with the edge runtime?

Good news, Node.js Middleware support landed in Next.js 15.2 (experimental). This is now ready for testing. For any issues you run into, please open new issues so we can track and address before marking it as stable. Thank you!

That sounds pretty exciting @leerob! I'll make sure to test it out.
Still, that doesn't quite answer my original question. I was looking for any recomendations that are production-ready. I would also consider the after API for my specific use case: https://nextjs.org/docs/app/api-reference/functions/after
