Dat is a decentralized data tool for distributing data small and large.
| Windows | Mac/Linux |
|---|---|
 |
Documentation for the Dat project is available at docs.dat-data.com.
- Live sync folders by sharing files as they are added to the folder.
- Distribute large files without copying data to a central server by connecting directly to peers.
- Intelligently sync by deduplicating data between versions.
- Verify data integrity using strong cryptographic hashes.
- Work everywhere, including in the browser and on the desktop.
Dat embraces the Unix philosophy: a modular design with composable parts. All of the pieces can be replaced with alternative implementations as long as they implement the abstract API.
- Dat CLI: command line tool
- Dat Desktop: desktop application
- dat.land: website application
This is the Dat CLI 1.0 release candidate (RC2). We are actively seeking feedback & developing this release candidate. Follow this issue for the Dat CLI road map discussion and see known RC2 issues.
Please note that previous versions of Dat (alpha, beta) are incompatible with the 1.0 release candidate.
To install the 1.0 release candidate from npm:
npm install dat -g

There are two main commands in dat:
- Share data:

You are now publishing that data from your computer. It will be publicly accessible as long as your terminal is open. The hash is a secret hash, your data is visible to anyone you send the hash to. As you add more files to the folder, dat will update and share the new files.
Your colleague can get data like this:
$ dat 2bede435504c9482910b5d4e324e995a9bc4d6f068b98ae03d97e8d3ac5f80ea download_dir

Download Finished, you may exit process
It will start downloading the data into the download_dir folder. Anyone who gets access to the unique dat-link will be able to download and re-host a copy of the data. It's distributed mad science!

Please see guidelines on contributing before submitting an issue or PR.
Clone this repository and in a terminal inside of the folder you cloned run this command:
npm link
This should add a dat command line command to your PATH. Now you can run the dat command to try it out.
