What Is LokiJS?

.

LokiJS is a document oriented database written in javascript, published under MIT License. Its purpose is to store javascript objects as documents in a nosql fashion and retrieve them with a similar mechanism. Runs in node (including cordova/phonegap and node-webkit), nativescript and the browser. LokiJS is ideal for the following scenarios:

1. client-side in-memory db is ideal (e.g., a session store)
2. performance critical applications
3. cordova/phonegap mobile apps where you can leverage the power of javascript and avoid interacting with native databases
4. data sets loaded into a browser page and synchronised at the end of the work session
5. node-webkit desktop apps
6. nativescript mobile apps that mix the power and ubiquity of javascript with native performance and ui

LokiJS supports indexing and views and achieves high-performance through maintaining unique and binary indexes (indices) for data.
