level-iterator-stream

Turn an abstract-leveldown iterator into a readable stream.

Usage

If you are upgrading: please see UPGRADING.md.

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

var db = leveldown(__dirname + '/db')
db.open(function (err) {
  if (err) throw err

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

Installation

$ npm install level-iterator-stream

API

stream = iteratorStream(iterator[, options])

Create a readable stream from iterator. 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 values / keys. Otherwise receive { key, value } objects.

When the stream ends, the iterator will be closed and afterwards a "close" event emitted.

.destroy() will force close the underlying iterator.
