Fast & simple storage - a Node.js-style HyperLevelDB wrapper
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.
If you are upgrading: please see UPGRADING.md.
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(Date.now())
db.db.liveBackup(name, function (err) {
if (!err) console.log('backup to %s was successful', name)
})
})See levelup and leveldown-hyper for more details.
