## What it is
LokiJS is a fast, embeddable, in-memory document-oriented NoSQL database written in JavaScript. It stores JavaScript objects as documents with indexing and dynamic views, and runs in browsers, Node.js, and mobile/hybrid environments like Cordova and NativeScript.

## Use cases
- embed an in-memory document database in a node app
- store session data client-side in the browser
- persist data offline in a cordova/phonegap mobile app
- query javascript object collections with indexes and views
- build a desktop app with a local nosql store
- sync in-browser data back to a server at end of session

## When to choose
- you need a fast embedded NoSQL store for JavaScript objects without a separate database server
- you're building browser, Electron, or hybrid mobile apps needing client-side persistence
- your dataset fits in memory and you need high-throughput reads/writes with indexing

## When to avoid
- you need a durable, multi-client server database with concurrent writes
- your data exceeds available memory
- you need advanced SQL features or strong ACID guarantees across processes

## Facets
- artifact type: library
- maturity: maintenance
- function: database, caching, serialization
- domain: databases, web-development, developer-tools
- platform: browser, cross-platform
- tags: nosql, in-memory-database, document-oriented, embedded-database, javascript, offline-sync, indexeddb, nodejs, mobile, desktop
