Hyperdrive does file synchronization and versioning, hyperdrive-archive-swarm does peer discovery over local networks and the Internet, and level provides a local LevelDB for storing metadata. More details are available in [How Dat Works](how-dat-works.md). The [dat](https://npmjs.org/dat) module itself is just some code that combines these modules and wraps them in a command-line API. - -Here's the minimal code needed to download data from a dat: - -```js -// run this like: node thisfile.js 4c325f7874b4070blahblahetc -// the dat link someone sent us, we want to download the data from it -var link = new Buffer(process.argv[2], 'hex') - -var Hyperdrive = require('hyperdrive') -var Swarm = require('hyperdrive-archive-swarm') -var level = require('level') -var raf = require('random-access-file') -var each = require('stream-each') - -var db = level('./dat.db') -var drive = Hyperdrive(db) -var archive = drive.createArchive(link, { - file: function (name) { - return raf(path.join(self.dir, name)) - } -}) -var swarm = Swarm(archive) - -archive.open(function (err) { - if (err) return console.error(err) - each(archive.list({live: archive.live}), function (data, next) { - var startBytes = self.stats.bytesDown - archive.download(data, function (err) { - if (err) return console.error(err) - console.log('file downloaded', data.relname) - next() - }) - }, done) -}) - -``` |
