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 a leveldown iterator into a readable stream

Example

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

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.

If options.decoder is passed, each key/value pair will be transformed by it. Otherwise, an object with { key, value } will be emitted.

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

.destroy() will force close the underlying iterator.
