ShareDrop

ShareDrop is HTML5 clone of Apple AirDrop service. It allows you to transfer files directly between devices, without having to upload them to any server first. It uses WebRTC for secure peer-to-peer file transfer and Firebase for presence management and WebRTC signaling.

ShareDrop allows you to send files to other devices in the same local network (i.e. devices with the same public IP address) without any configuration - simply open https://www.sharedrop.io on all devices and they will see each other. It also allows you to send files between networks - just click + button in the top right corner of the page to create a room with unique URL and share this URL with other people you want to send a file to. Once they open this page in a browser on their devices, you'll see each other's avatars.

The main difference between ShareDrop and AirDrop is that ShareDrop requires Internet connection to discover other devices, while AirDrop doesn't need one - it creates ad-hoc wireless network between them. On the other hand, ShareDrop allows you to share files between mobile (Android) and desktop devices and between networks as well.

Supported browsers

  • Chrome (desktop and Android) 33+
  • Opera (desktop and Android) 20+
  • Firefox (desktop and Android) 28+ (though we suggest using Chrome or Opera for transferring larger files)

How to set it up for local development

  1. Setup Firebase:
    1. Sign up for a Firebase account and create a database.
    2. Go to "Security Rules" tab, click "Load Rules" button and select firebase_rules.json file.
    3. Take note of your database URL and its secret, which can be found in "Secrets" tab.
  2. Run npm -g install grunt-cli to install Grunt.
  3. Run npm install to install NodeJS dependencies.
  4. Run bundle install to install Ruby dependencies.
  5. Run cp .env{.sample,} to create .env file. This file will be used by Grunt to set environemnt variables when running the app locally. You only need NEW_RELIC_* variables in production.
  6. Run grunt serve to start the app.
  7. Run grunt build to build production version of the app to dist directory.

Deployment

When deploying to Heroku, use multi buildpack.

For new apps:

heroku create myapp --buildpack https://github.com/ddollar/heroku-buildpack-multi.git

For existing apps:

heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git
