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.
