datakey

Provides auto generating keys from objects. Uses '\x00' (null) as default divider.

.get(data, keys)

    var Datakey = require('datakey');

    var datakey1 = new Datakey(),
    keys = ['ID', 'name'],
    testData = { ID: 1, name: 'AA', result: 1000 },
    key;

    datakey1.get(testData, keys); // retruns: '1\x00AA'

    var datakey2 = new Datakey({divider: '!'});
    datakey2.get(testData, keys); // retruns: '1!AA'

.levelup(data, keys)

converts data into a levelup batch transaction object

    var Datakey = require('datakey');

    var datakey = new Datakey(),
    keys = ['ID', 'name'],
    testData = [{ ID: 1, name: 'AA', result: 56 },{ ID: 1, name: 'AB', result: 67 }],
    key;

    datakey.levelup(testData, keys)[0].key; // retruns: '1\x00AA'

    datakey.levelup(testData, keys)[1].value.name; // retruns: 'AB'

    //level up batch transaction (https://github.com/rvagg/node-levelup#batch)
    leveldb.batch(datakey.levelup(testData, keys));
