Usage

Use to create or read Dat Archives on the file system in Node applications.

var Dat = require('dat-node')

Dat(dir, opts, function (err, dat) {
  console.log(dat.path) // dat is created here with a .dat folder

  var db = dat.db // level db in .dat folder
  var archive = dat.archive // Dat Archive

  // Join the network
  var network = dat.network(opts) 
  network.swarm // hyperdrive-archive-swarm

  // Track stats
  var stats = dat.stats() // hyperdrive-stats

  // Import Files
  var importer = dat.importFiles(opts, cb) // hyperdrive-count-import
})

API

`Dat(dir, [opts], cb)``

Initialize a Dat Archive in dir. If there is an existing Dat Archive, the archive will be resumed.

Initial opts can include:

opts = {
  db: level(path/.dat), // level-db compatible database
  key: '<dat-key>', // existing key to create archive with or resume
  resume: Boolean, // fail if existing archive differs from opts.key

  // Hyperdrive archive options
  live: Boolean, // archive.live setting (only set if archive is owned)
  file: raf(), // file option for hyperdrive.createArchive()

  // dat-folder-db options
  dbName: '.dat' // directory name for level database
}

The callback includes a dat object that has the following properties:

dat.archive

Hyperdrive archive instance.

dat.db

.dat folder database

dat.path

Path of the Dat Archive

---

dat-node provides an easy interface to common Dat modules for the created Dat Archive on the dat object provided in the callback:

var network = dat.network([opts])

Join the Dat Network for your Dat Archive.

opts are passed to the swarm module. See hyperdrive-archive-swarm for options.

network.swarm

discovery-swarm instance.

network.peers()

Get number of peers connected to you.

var importer = dat.importFiles([opts], [cb])

Import files to your Dat Archive from the directory using hyperdrive-import-files. Options are passed to the importer module. cb is called when import is finished.

dat-node provides a default ignore option, ignoring the .dat folder and all hidden files or directories.

Returns the importer event emitter.

var stats = dat.stats()

hyperdrive-stats instance for the Dat Archive. Stats are stored in a sublevel database in the .dat folder.
