dat-walk

Recursive directory walker for dat archives.

Supports both raw hyperdrive instances and Beaker Browser's DatArchive API. With scoped-fs you can use it on your local file system as well.

Installation

In Beaker or Webrun you can import the module directly in your code:

import walk from 'dat://brecht.pamphlets.me/lib/dat-walk/v2.1.js'

Note that it's advised to always use the dat protocol for this. HTTPS might be fine for testing, but I can't guarantee the required reliability and performance for production usage.

If you need dat-walk in Node.js, you can get it from NPM:

npm install dat-walk

Usage

This package exports two modules. The default require('dat-walk') works with async iteration, whereas require('dat-walk/stream') uses standard Node streams. Both these examples log all file paths of a given dat to the console.

// Async iteration
var walk = require('dat-walk')

async function main () {
  var dat = DatArchive.load(key)

  for await (var file of walk(dat)) {
    console.log(file)
  }
  console.log('done!')
}

main()

// Node stream
var hyperdrive = require('hyperdrive')
var walk = require('dat-walk/stream')

var dat = hyperdrive(key)
var stream = walk(dat, 'subdir')

stream.on('data', console.log)
stream.on('end', () => console.log('done!'))
