NuGetMirror.exe is a command line tool to mirror nuget.org to disk, or any NuGet v3 feed. It supports filtering package ids and wildcards to narrow down the set of mirrored packages.

NuGet.CatalogReader is a library for reading package ids, versions, and the change history of a NuGet v3 feeds or nuget.org.

1. Download the latest nupkg from NuGet.org
2. Extract tools/NuGetMirror.exe to a local folder and run it.

1. dotnet tool install -g nugetmirror
2. nugetmirror should now be on your PATH

Mirror all packages to a folder on disk.

NuGetMirror.exe nupkgs https://api.nuget.org/v3/index.json -o d:\tmp

NuGetMirror can be used to continually sync the latest packages. Runs store to the last commit time to disk, future runs will resume from this point and only get new or updated packages.

Discover all packages in a feed using GetFlattenedEntriesAsync. To see the complete history including edits use GetEntriesAsync.

var feed = new Uri("https://api.nuget.org/v3/index.json");

using (var catalog = new CatalogReader(feed))
{
    foreach (var entry in await catalog.GetFlattenedEntriesAsync())
    {
        Console.WriteLine($"[{entry.CommitTimeStamp}] {entry.Id} {entry.Version}");
        await entry.DownloadNupkgAsync(@"d:\output");
    }
}

NuGet v3 feeds that do not have a catalog can be read using FeedReader.

var feed = new Uri("https://api.nuget.org/v3/index.json");

using (var feedReader = new FeedReader(feed))
{
    foreach (var entry in await feedReader.GetPackagesById("NuGet.Versioning"))
    {
        Console.WriteLine($"{entry.Id} {entry.Version}");
        await entry.DownloadNupkgAsync(@"d:\output");
    }
}
