An Azure Blob Storage extension for tusdotnet; .NET's most popular implementation of the tus protocol.

What is tus?

Tus is a web based protocol for resumable uploads. Implementations and client libraries exist for many platforms.

What is tusdotnet?

tusdotnet is a popular implementation of the tus protocol for .net.

Why do I need Xtensible.TusDotNet.Azure?

Tusdotnet only comes with a disk storage implementation. This extension allows you to use blobstorage instead of local (or network attached) disk.

Implemented Extensions

The tus protocol offers a few extensions. The following extensions are implemented:

  • Termination - Allows for deletion of completed and incomplete uploads.
  • Expiration - Server will consider uploads past a certain time expired and ready for deletion.

Why aren't the following supported?

  • Checksum - The code for checksum (using md5) is actually written and can be enabled by #defining ENABLE_CHECKSUM. It is disabled because it only works for upload chunks ⇐ 4MB, which is the buffer size used to send data to Azure. Anything beyond 4MB would be inefficient, because we'd have to download the bits from Azure to verify the checksum. This implementation did not want to force upload limitations on consuming code, so this extension was disabled. If you care about this feature and are ok with limiting chunk size to 4MB you can compile with it turned on.

  • Pipelines - tusdotnet supports pipelines for .net core 3.1+, which is more efficient than the streams implementation. I haven't gotten to this yet, but will happily accept pull requests.


Azurite is the latest, and recommended Azure Storage emulator to use for testing and local development. Unfortunately, it does not yet support tags (see issue). This is problematic because tags is how this library queries for expired files. To work around this, I have split out the expiration stuff into a separate interface ITusExpirationDetailsStore and implemented NullExpirationDetailsStore.

This allows you to use an external database (for just dev, or both prod and dev), or you can use NullExpirationDetailsStore in dev to forego using the expiration feature when using Azurite.
