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.

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.
