Levellevel-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.
