Hey! 👋 It looks like you're trying to import an npm module without a build-step. Workers only natively support modules that are located in your upload directory, not node_modules. Check out https://miniflare.dev/recipes/esbuild.html for an example of using esbuild to bundle your code first. Let me know if you have any issues with this. 👍

Hey @mrbbot thanks for the quick answer

I am using the rollup configuration from cloudflare typescript template here : https://github.com/cloudflare/durable-objects-typescript-rollup-esm

I guess the rollup config is missing some option ?

I ll investigate more and might as well switch to esbuild that I am using for my frontend through vite anyway.

@janat08 , @wighawag, @mrbbot , I am having the same problem with a different package. I am getting
MiniflareError: Unable to resolve "dist/index.mjs" dependency "perf_hooks": no matching module rules
and I am using the rollback template setup. Any hints for what would fix it?
