Datt is a node.js and web browser app for decentralized content sharing with integrated payments. It is currently undergoing heavy development and has not yet reached alpha. Our issues are tracked on GitHub. Check out the blog or twitter to stay up-to-date on progress.

Datt can be built and run on Linux. It is not tested on Mac or Windows, but should work with minimal or no changes on those platforms. To help program the Datt application, first be sure you are running node 4.2:

> node --version
v4.2.1

Then clone this repo:

git clone https://github.com/dattnetwork/datt.git

Then install the dependencies:

cd datt
npm install

To run all of Datt tests:

npm test

You may wish to run the node tests while you edit files:

npm run watch-test-node

...then save a file and the tests will run.

To run only the browser tests:

npm run serve

This will serve the files, run the PeerJS rendezvous server, and run a browser-sync proxy server that will automatically refresh your browser when the files change. You can then access the tests at:

http://localhost:3040/tests.html

Or access the app itself at:

http://localhost:3040/

The app makes use of IndexedDB and Web RTC in a browser. Each "domain" has its own IndexedDB and p2p connections. This means if you run the app on a different port, it's as though you're running the app as a different person from a different computer. This makes it easy to test the p2p properties of Datt if you simply deliver the same app from different ports. To facilitate this, the ports 3040 - 3044 are all assigned to simply deliver the app. So feel free to open up these other ports to see the same app but with a different user, content, and p2p connections:

http://localhost:3040/
http://localhost:3041/
http://localhost:3042/
http://localhost:3043/
http://localhost:3044/

To run in testnet mode:

FULLNODE_NETWORK=testnet DATT_BLOCKCHAIN_API_URI=https://test-insight.bitpay.com/api/ npm run serve
