Package Exports

level-iterator-stream

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (level-iterator-stream) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
