Fast & simple storage - a Node.js-style HyperLevelDB wrapper


Build Status dependencies

This is a convenience package that bundles the current release of LevelUP and LevelDOWN-Hyper and exposes LevelUP on its export.

Use this package to avoid having to explicitly install LevelDOWN-Hyper when you want to use LevelDOWN-Hyper with LevelUP.


Basic usage for putting and getting data:

var level = require('level-hyper')

// 1) Create our database, supply location and options.
//    This will create or open the underlying LevelDB store.
var db = level('./mydb')

// 2) put a key & value
db.put('name', 'Level', function (err) {
  if (err) return console.log('Ooops!', err) // some kind of I/O error

  // 3) fetch by key
  db.get('name', function (err, value) {
    if (err) return console.log('Ooops!', err) // likely the key was not found

    // ta da!
    console.log('name=' + value)

The .liveBackup() method is accessible on the underlying LevelDOWN-Hyper object:

var level = require('level-hyper')
var db = level('./mydb')
db.on('ready', function () {
  var name = String(
  db.db.liveBackup(name, function (err) {
    if (!err) console.log('backup to %s was successful', name)
