Uppy

Uppy is a sleek, modular JavaScript file uploader that integrates seamlessly
with any application. It’s fast, has a comprehensible API and lets you worry
about more important problems than building a file uploader.

Fetch files from local disk, remote URLs, Google Drive, Dropbox, Box,
Instagram or snap and record selfies with a camera
Preview and edit metadata with a nice interface
Upload to the final destination, optionally process/encode

and its plugins.

Features

Lightweight, modular plugin-based architecture, light on dependencies :zap:
Resumable file uploads via the open tus standard, so large
uploads survive network hiccups
Supports picking files from: Webcam, Dropbox, Box, Google Drive, Instagram,
bypassing the user’s device where possible, syncing between servers directly
via @uppy/companion
Works great with file encoding and processing backends, such as
Transloadit, works great without (all you need is
to roll your own Apache/Nginx/Node/FFmpeg/etc backend)
Sleek user interface :sparkles:
Optional file recovery (after a browser crash) with
Golden Retriever
Speaks several languages (i18n) :earth_africa:
Built with accessibility in mind
Free for the world, forever (as in beer 🍺, pizza 🍕, and liberty 🗽)
Cute as a puppy, also accepts cat pictures :dog:

Installation

Add CSS
uppy.min.css,
either to your HTML page’s or include in JS, if your bundler of choice
supports it.

Alternatively, you can also use a pre-built bundle from Transloadit’s CDN: Smart
CDN. In that case Uppy will attach itself to the global window.Uppy object.

⚠️ The bundle consists of most Uppy plugins, so this method is not recommended
for production, as your users will have to download all plugins when you are
likely using only a few.

Plugins

UI Elements

Dashboard — universal UI with previews,
progress bars, metadata editor and all the cool stuff. Required for most UI
plugins like Webcam and Instagram
Progress Bar — minimal progress bar
that fills itself when upload progresses
Status Bar — more detailed progress,
pause/resume/cancel buttons, percentage, speed, uploaded/total sizes (included
by default with Dashboard)
Informer — send notifications like “smile”
before taking a selfie or “upload failed” when all is lost (also included by
default with Dashboard)

Sources

Drag & Drop — plain drag and drop area
File Input — even plainer “select files”
button
Webcam — snap and record those selfies 📷
ⓒ Google Drive — import files from
Google Drive
ⓒ Dropbox — import files from Dropbox
ⓒ Box — import files from Box
ⓒ Instagram — import images and videos
from Instagram
ⓒ Facebook — import images and videos from
Facebook
ⓒ OneDrive — import files from Microsoft
OneDrive
ⓒ Import From URL — import direct URLs from
anywhere on the web

The ⓒ mark means that @uppy/companion, a
server-side component, is needed for a plugin to work.

Destinations

Tus — resumable uploads via the open
tus standard
XHR Upload — regular uploads for any
backend out there (like Apache, Nginx)
AWS S3 — plain upload to AWS S3 or
compatible services
AWS S3 Multipart — S3-style
“Multipart” upload to AWS or compatible services

File Processing

Transloadit — support for
Transloadit’s robust file uploading and encoding
backend

Miscellaneous

Golden Retriever — restores files
after a browser crash, like it’s nothing
Thumbnail Generator — generates
image previews (included by default with Dashboard)
Form — collects metadata from
right
before an Uppy upload, then optionally appends results back to the form
Redux — for your
emerging time traveling needs

Native with Expo

Browser Support

We aim to support recent versions of Chrome, Firefox, and Safari.

FAQ

Why not use ?

Having no JavaScript beats having a lot of it, so that’s a fair question!
Running an uploading & encoding business for ten years though we found that in
cases, the file input leaves some to be desired:

We received complaints about broken uploads and found that resumable uploads
are important, especially for big files and to be inclusive towards people on
poorer connections (we also launched tus.io to attack that
problem). Uppy uploads can survive network outages and browser crashes or
accidental navigate-aways.
Uppy supports editing meta information before uploading.
Uppy allows cropping images before uploading.
There’s the situation where people are using their mobile devices and want to
upload on the go, but they have their picture on Instagram, files in Dropbox
or a plain file URL from anywhere on the open web. Uppy allows to pick files
from those and push it to the destination without downloading it to your
mobile device first.
Accurate upload progress reporting is an issue on many platforms.
Some file validation — size, type, number of files — can be done on the client
with Uppy.
Uppy integrates webcam support, in case your users want to upload a
picture/video/audio that does not exist yet :)
A larger drag and drop surface can be pleasant to work with. Some people also
like that you can control the styling, language, etc.
Uppy is aware of encoding backends. Often after an upload, the server needs to
rotate, detect faces, optimize for iPad, or what have you. Uppy can track
progress of this and report back to the user in different ways.
Sometimes you might want your uploads to happen while you continue to interact
on the same single page.

Not all apps need all these features. An is fine in many
situations. But these were a few things that our customers hit / asked about
enough to spark us to develop Uppy.

Why is all this goodness free?

Transloadit’s team is small and we have a shared ambition to make a living from
open source. By giving away projects like tus.io and
Uppy, we’re hoping to advance the state of the art, make life
a tiny little bit better for everyone and in doing so have rewarding jobs and
get some eyes on our commercial service:
a content ingestion & processing platform.

Our thinking is that if only a fraction of our open source userbase can see the
appeal of hosted versions straight from the source, that could already be enough
to sustain our work. So far this is working out! We’re able to dedicate 80% of
our time to open source and haven’t gone bankrupt yet. :D

Does Uppy support S3 uploads?

Yes, please check out the docs for more
information.

Can I use Uppy with Rails/Node.js/Go/PHP?

Yes, whatever you want on the backend will work with @uppy/xhr-upload plugin,
since it only does a POST or PUT request. Here’s a
PHP backend example.

If you want resumability with the Tus plugin, use
one of the tus server implementations 👌🏼

And you’ll need @uppy/companion if you’d
like your users to be able to pick files from Instagram, Google Drive, Dropbox
or via direct URLs (with more services coming).
