We recommend node version 0.12 or above. You can check your node version by running node -v on the command line.

$ node -v
v0.12...

npm install dat -g

The -g means "install globally" which makes the dat command available in your command line path.

If it all worked correctly, you should see something like this when you type dat.

usage: dat <command(s)> [--flag] [--key=value]

commands:
  init        initialize a new dat store in a directory
  status      show current status
  log         view a list of recent changes
  clone       download and make a full copy of a remote dat
  ...

Dat is still in beta. If you have any trouble, it's probably because we did something wrong!

Please tell us by opening an issue here or asking us a question in #dat on IRC in freenode.

The dat module is designed with a small-core philosophy. It defines an API for reading, writing and syncing datasets and is implemented using Node.js.

Internally dat has two kinds of data storage: tabular and blob. The default tabular data store is LevelDB and the default blob store stores files on a content-addressable blob store. Both of these default backends can be swapped out for other backends.

If it's broken, you can probably help fix it!

• Start by checking out our help wanted issue tag.
• Help us with the module wishlist! We hope to connect every database backend to dat, but we can't do it without your help!

You can install the latest development version with git:

git clone git://github.com/maxogden/dat.git
cd dat
npm install
npm link
