Exactly four years after the last major release of tusd, version 1.0.0, it is time for another big announcement: we are happy to say that tusd v2 is finished! The release is ready for production and has been battle tested at scale at Transloadit in the past months. tusd is our server implementation in Go for the tus resumable upload protocol.
The Node.js tus server has been revived and is now officially semver stable! It has been completely rewritten in TypeScript and was split into separate packages. There is a new system for events and hooks, as well as elaborate docs with examples. And those are just a few of the many fixes and features that we will dive into below.
In the past year, we have worked together with the HTTP working group inside the Internet Engineering Task Force (IETF) to advance the state of resumable uploads and craft an official RFC for better file uploads over the internet. In this post, we share the latest developments from this journey.
tus is a protocol based on HTTP for resumable file uploads. Resumable here means that an interrupted upload can carry on without re-uploading already uploaded data again. An interruption may happen willingly, if the user wants to pause while switching to another workspace, or by accident in case of a network issue or server outage. When resumability is implemented with automatic retries, the user does not need to notice there was an interruption. Since HTTP/1.1 such a resumability is available for file downloads already but not for file uploads as tus offers.
Seven years ago, in November 2015, we announced the release of tus 1.0, the first major and stable version of our uploading protocol. In the past months, we have been actively working on the next steps for tus and wanted to share early details about tus 2.0.
Today we are excited to announce that tusd is now also able to store uploaded files in the Azure Cloud Storage! Just like all tus servers, tusd's role is to accept incoming uploads from the tus clients and then relay them to the underlying storage providers. For a long time has tusd already supported storing uploads locally on disk, on AWS S3 and Google's Cloud Storage. Thanks to an incredible contribution from Ole-Martin Bratteng, this support has been expanded to also cover the Azure Cloud Storage!
Since the tus project began in 2013, countless contributors with various technical backgrounds have joined our mission and helped move the protocol forward. Many people have contributed their knowledge to tus over these years, some as front-end developers and server engineers, and others as security professionals or network administrators. This variety is of great importance as it allows us to look at problems from different angles and find the optimal solution for everyone involved. Furthermore, since we want the tus protocol to be available and usable for many applications, it's essential to get feedback from as many people as possible.

Today, we are thrilled to announce the v1.0.0 release of our tusd project, the official reference implementation for the tus protocol. Don't let yourself be fooled by the version number, tusd has been production-ready and battle-tested for many years already.
A bit less than two months ago, we released version 1.6.0 of tus-js-client, our open source tus implementation for JavaScript environments. Usually, we don't write a blog post about a specific release, but this one is very special to us for two reasons:
Just a quick update from the team!
Yes, oddly enough, this seems to be the case! A while ago, we noticed something really interesting on tus.io, our open protocol for resumable uploads: a comment from Jaroslaw Wasilewski mentioned that tus was being used to support firefighting rescue operations. Now that is exciting news!
With their Simple Storage System (S3), Amazon Web Services has built one of the major providers of cloud storage for applications ranging from small side projects to enterprise systems. Since the introduction of flexible storage back-ends for the official tusd server, an integration with S3 has been a much desired feature by our users. We are happy to announce that we are now able to deliver on this request. During the time it took to create this, we had to deal with various peculiarities of Amazon's service and were able to gain a lot of experience. In this post, we want to focus on the downsides of building a tus server on top of S3 and share some of our recently acquired knowledge with you.
As time progresses, we share ever larger media files from our phones and desktops. More than often, however, complications arise during this process. Whether it is through servers misbehaving or mobile users switching to a WiFi connection, the outcome is the same: 'upload interrupted'.
Here's a quick update on the status of the project.
More than a year ago the last release, 0.2.2 was published. Now the final 1.0
release is just around the corner introducing breaking changes and a lot of new
features.
This is a minor protocol release:

After releasing our first draft a few weeks ago, we received an incredible amount of feedback and suggestions. Based on this feedback as well as discussing the problems with the IETF HTTPbis Working Group, we identified a few key issues with v0.1 of the protocol:
tl;dr: We are happy to announce version 0.1 of the tus resumable upload protocol and are interested in your feedback!
Hey everybody, we're starting a new blog here to discuss file uploading, and the protocol we are working on. So keep an eye on this space!
