LokiJS

Overview

LokiJS is a document oriented client side database written in javascript. Its purpose is to store javascript objects as documents in a nosql fashion and retrieve them with a similar mechanism. Runs in node and the browser. LokiJS is ideal for the following scenarios:

  1. where a lightweight in-memory db is ideal
  2. cross-platform mobile apps where you can leverage the power of javascript and avoid interacting with native databases
  3. data sets are not so large that it wouldn't be a problem loading the entire db from a server and synchronising at the end of the work session

LokiJS has limited supports for indexing, transactions, couchdb-style views.

In a nodejs/node-webkit environment LokiJS also persists to disk whenever an insert, update or remove is performed.

Current state

LokiJS is currently at an alpha stage, it is stable but not 100% feature complete. As LokiJS is written in Javascript it can be run on any environment supporting javascript such as browsers, node.js/node-webkit, hybrid mobile apps (such as phonegap/cordova), or the jvm through engines such as rhino.

Installation

For browser environments you simply need the lokijs.js file contained in src/

You can use bower to install lokijs with bower install lokijs

For node environments you can install through npm install lokijs.

Roadmap

  • Wider and more specific support for indexes such as unique, compound.
  • Replication across nodes.
