What is Sleet?

Sleet is a static NuGet package feed generator.

  • Serverless. Create static feeds directly on Azure Storage, Amazon S3 or another S3 compatible storage. No compute required.
  • Cross platform. Sleet is built in .NET, it can run on .NET Framework, Mono, or dotnet CLI
  • Fast. Static feeds are created using the NuGet v3 feed format.
  • Simple. Sleet is a simple command line tool that can add, remove, and update packages.
  • Flexible. Configuration and credentials can be set using files, env vars, command line args, or AWS specific patterns to support a variety of workflows and CI builds.

Why use static feeds?

  • Package binaries are typically kept outside of git repos, static feeds provide a long term storage solution that can be paired with checked in code.
  • NuGet feeds are typically read for restore far more than they are updated.
  • Cloud storage accounts are a cheap and secure way to share nupkgs for public feeds.
  • You keep full control of your packages.

Getting Sleet

Sleet was created to achieve the original goals of the NuGet v3 feed format: Provide maximum availability and performance for NuGet restore by using only static files.

The v3 feed format was designed to do all compute when pushing a new package since updates are infrequent compared to the number of times a package is read for restore. Static files also remove the need to run a specific server to host the feed, allowing a simple file service to handle it.
