level-iterator-stream

Turn an abstract-leveldown iterator into a readable stream.

Usage

If you are upgrading: please see UPGRADING.md.

const iteratorStream = require('level-iterator-stream')
const leveldown = require('leveldown')

const db = leveldown(__dirname + '/db')

db.open(function (err) {
  if (err) throw err

  const stream = iteratorStream(db.iterator())
  stream.on('data', function (kv) {
    console.log('%s -> %s', kv.key, kv.value)
  })
})

Install

With npm do:

npm install level-iterator-stream

API

stream = iteratorStream(iterator[, options])

Create a readable stream from iterator. The options are passed down to the require('readable-stream').Readable constructor, with objectMode forced to true. Set options.keys or options.values to false to only get keys or values. Otherwise receive { key, value } objects.

Upon stream end or .destroy() the iterator will be closed after which a close event is emitted on the stream.
