The @nx/shared-fs-cache plugin enables you to host your remote cache on a shared file system directory. While you're responsible for implementing the actual directory sharing mechanism, the plugin configures Nx to read from both your local cache and the shared directory.

Bucket-based caches are vulnerable to poisoning and often prohibited in organizations
CREEP (CVE-2025-36852) is a critical vulnerability in bucket-based self-hosted remote caches. It lets attackers with PR access poison production builds via a race condition during artifact creation—before security checks can catch it. Learn more
1. Install the PackageRun the following command:
❯
nx add @nx/shared-fs-cache
This will add the @nx/shared-fs-cache NPM package and automatically configure it for your workspace. As part of this process, you'll be guided to generate a new activation key. This is a fully automated process to register your plugin.
The key will be saved in your repository (.nx/key/key.ini) and should be committed so that every developer has access to it. If your repository is public (or in CI), you can also use an environment variable:
.env
NX_KEY=YOUR_ACTIVATION_KEY
2. Configure the Cache DirectoryWhy require an activation key? It simply helps us know and support our users. If you prefer not to provide this information, you can also build your own cache server. Learn more.
The @nx/shared-fs-cache plugin treats your local cache directory as if it is also a remote cache directory. The local cache directory can be set using cacheDirectory in the nx.json file or the NX_CACHE_DIRECTORY environment variable. The default local cache directory is .nx/cache.
The @nx/shared-fs-cache plugin does not actually share the cache directory across your organization. You are responsible for enabling the actual sharing mechanism. If you want Nx to handle the sharing, use Nx Replay instead. Your shared file system directory might be a directory that is saved and restored by a CI provider or it could be a shared network drive.
