Promise based leveldb interface
npm install then-levelup
// having run npm install level
var db = require('then-levelup')(require('level')('./mydb'));
// use like level-up except APIs return promises instead of taking callbacks
db.put('foo', 'bar').then(function () {
return db.get('foo');
}).then(function (value) {
assert(value === 'bar');
}).done(function () {
console.log('tests passed');
});MIT
