Peer-to-peer file transfers in your browser
Using WebRTC, FilePizza eliminates the initial upload step required by other web-based file sharing services. When senders initialize a transfer, they receive a "tempalink" they can distribute to recipients. Upon visiting this link, recipients' browsers connect directly to the sender’s browser and may begin downloading the selected file. Because data is never stored in an intermediary server, the transfer is fast, private, and secure.
A hosted instance of FilePizza is available at file.pizza.
The recommended way to deploy FilePizza is as a Docker container.
$ docker run -p 8080:8080 -e PORT=8080 -it kern/filepizza:latest
You can also use zeit/now:
$ now --npm --public -e NODE_ENV=production
If you'd like to use Twilio's STUN/TURN service for better connectivity behind NATs, you can specify your SID and token using the
TWILIO_TOKEN environment variables, respectively.
$ git clone https://github.com/kern/filepizza.git $ npm install $ npm run-script build $ npm start
FilePizza is an isomorphic React application which uses the Flux application architecture. ES6 features are used liberally and compiled using Babel. Views are rendered on the server, store data is serialized and sent to the client, which then picks up where the server left off.
lib/client.js are the server and client entrypoints, respectively.
lib/actions/ contain the corresponding Flux modules, implemented using alt.
lib/routes.js serves as the isomorphic routes file using react-router.
Where are my files sent? Your files never touch our server. Instead, they are sent directly from the uploader's browser to the downloader's browser using WebTorrent and WebRTC. This requires that the uploader leave their browser window open until the transfer is complete.
Can multiple people download my file at once? Yes! Just send them your tempalink.
How big can my files be? Chrome has issues supporting files >500 MB. Firefox does not have any issues with large files, however.
What happens when I close my browser? The tempalink is invalidated. If a downloader has completed the transfer, that downloader will continue to seed to incomplete downloaders, but no new downloads may be initiated.
Are my files encrypted? Yes, all WebRTC communications are automatically encrypted using public-key cryptography.
My files are sending slowly! Transfer speed is dependent on your network connection.
If you receive a
Error: EMFILE, too many open files error when running
npm start on a Mac, this is a result of Browserify's compilation step opening up a
large number of npm modules all at once. You'll have to increase the maximum
number of open files allowed on your system:
$ sysctl -w kern.maxfiles=20480
