The future of nx-remotecache-*

Nrwl Nx just introduced us to Powerpack. It's the clear successor of the remote cache setup and officially supports custom caching solutions. This will mark the end of the nx-remotecache-* packages as custom caching solutions based on the filesystem won't work anymore starting with Nx 21.

Powerpack fills exactly the void that nx-remotecache-custom filled. Therefore I'm happy to give this topic back to the creators behind Nx. Thanks for the great ride – we reached over 114,000 weekly downloads on npm as I'm writing this 🥳

Feel free to read the Introduction to Powerpack by Jeff yourself. If you have any further questions checkout the pinned GitHub issue.

Cheers, Niklas 👋

Critical Vulnerability: CVE-2025-36852

Due to the way remote caching with shared buckets works, cache poisoning is possible via anything that runs pipelines on untrusted code (e.g. a pull request). You can read-up on the vulnerability in this document from NX or here on nist. There's no planned fix for this vulnerability. I still recommend to use the official solution powerpack by Nx instead.

nx-remotecache-minio

A task runner for @nrwl/nx that uses an Minio Storage as a remote cache. This enables all team members and CI servers to share a single cache. The concept and benefits of computation caching are explained in the NX documentation.

This package was built with nx-remotecache-custom 🙌

Run it 🚀

Running tasks should now show the storage or retrieval from the remote cache:
