Uppy 0.14: Responsive Dashboard, Standalone & Pluggable Server, Dropbox

Feb 13, 2017

Hi! Hope y’all have had great holidays! 🎄 Which reminds us, we still have a gift for you — and we even wrapped it in a package (npm). Look inside and you’ll find that Uppy 0.14!

“But wait”, you might ask, “where is the 0.13 release that we have been waiting for?”

Well, let’s just say we are superstitious like that. You won’t see us coding under any ladders either! And we were also in the middle of the holiday season, so we decided to call 0.13 “The Release That Wasn’t” and skip it.

Let’s take a look at what Uppy 0.14 has in store for you.

Uppy 0.12: Responsive. Cancel. Feedback. Refreshed ES6 server

Dec 7, 2016

Hello! Here’s what’s new in Uppy 0.12.

Dashboard: local mode and multipart uploads support in UI

Prior to this release, we’ve optimized the Dashboard for usage with multiple “acquire plugins”, say Webcam + Google Drive. But sometimes all you need is “local disk” with drag & drop support, nice file previews and progress. And now the Dashboard UI works great with that use case out of the box. When you don’t add (.use) any acquire plugins, it looks like this:

Also (prior to this release), we’ve built the Dashboard to work well with tus resumable uploads. That’s why you can pause and resume individual uploads, as well as all at once. But if you use an endpoint that is not yet ready for the future and upload resumability (here’s how to fix that, by the way), the Dashboard UI will show regular “cancel” buttons instead of pause/resume.

Dashboard is gradually becoming more mobile friendly too, but we’ll be saving some of that stuff for the next release.


Uppy server has undergone a quite a few changes, including the build setup:

  • We are using ES2015, transpiling to ES5 with Babel.
  • Added linting, lint-staged, pre-commit all that good stuff.
  • Added npm run release command that publishes releases for us.
  • Google Drive is working again on the Uppy Server side.
  • Refactoring, error handling and more minor improvements.

Uppy 0.11: StatusBar, research, https and API docs

Nov 15, 2016

Hey everyone! It has been a while since we last shared some news about our progress and we can’t wait to let you know what’s up(py)!

In October, we have been working hard to get Uppy 0.11 ready for release. This entailed, among other things, doing a write-up of our general architecture, bringing in a friend to look at what we’ve been up to, experimenting with Redux, and updating the Dashboard UI and website example.

Here’s what we have been up to, in some more detail.

Uppy 0.10: Getting together, the future, Google Drive UI, exposed events

Sep 28, 2016

Hi! Another month has passed and we have just released a new version of Uppy. Here’s what we’ve been up to.

Thinking about the future 🔮

We have been spending quite a lot of time thinking about Uppy’s future and the direction in which we would like to take this project. Our primary concern is making Uppy as flexible as possible as well as compatible with popular libraries, such as React and React Native. We also want to make it easy to port Uppy to any environments or ecosystems that are not officially supported.

We have done a lot of research. We created prototypes of Uppy React components and we also created a new module that we like to call “Uppy Base.” uppy-base is a thin module containing reusable functionality from some of our plugins that can be used in any ecosystem or environment, without being opinionated about the UI.

Uppy version 0.8 released: The Webcam Edition and Meta Data

Aug 17, 2016

We have just released Uppy 0.8.0 and we can’t wait to tell you more about it. Along with various under-the-hood improvements, this release also contains some very visible upgrades. You can read below for further details.

Including Meta Data

While fetching your files, Uppy is now also able to supply some custom metadata to go along with them. So far, there are three components in place for that: Core API (core:update-meta event), MetaData plugin, and a new panel in Dashboard UI called File Card, which looks like this:

metadata dashboard UI, editing file name, future size and adding description

Uppy: let’s teach an old dog some new tricks

Jul 15, 2016

For the past six months, we have been working hard on We feel that it is high time we gave you a look behind the scenes: what are we working on, and why.

The way uploading works has not changed in a meaningful way since the days of our trusty old 56 kbit/s modems. Of course, files have gotten bigger and speeds have increased, but that is more or less all there is to say. If it were up to us – and we hope it is – that is all about to change.

We at Transloadit are on a mission to change the way the world does uploading. To accomplish this, our first step has been to develop an open protocol for resumable file uploads, called ‘tus’. Finally, that 2GB video upload from your smartphone doesn’t have to start over when your train passes through a tunnel! The protocol got Hacker News excited on several occasions and is being deployed by, among others, our friends at Vimeo. Now that a stable version 1.0 of ‘tus’ has been released, it is time to put it to the test. A protocol without real-world applications is nothing more than a meaningless document, after all.

We are therefore excited to tell you about Uppy: the file uploader that will certainly fetch more than just your newspaper.
