## What it is
persistence.js is an asynchronous JavaScript object-relational mapper (ORM) library usable in both the browser and on Node.js servers, with shared data models between them. It supports HTML5 WebSQL, Google Gears, MySQL (via node-mysql), and in-memory/localStorage data stores, with plugins for full-text search, schema migrations, and server synchronization.

## Use cases
- store data offline in the browser with WebSQL
- share data models between browser and node.js server
- map JavaScript objects to a relational database asynchronously
- sync client-side database with a remote server
- run database schema migrations in JavaScript
- add full-text search to a client-side database

## When to choose
- building an older mobile web app needing offline storage on WebKit browsers
- you want one ORM working in both browser and Node.js
- you need client-server database synchronization in JavaScript

## When to avoid
- starting a new modern project (WebSQL and Gears are deprecated)
- you need an actively maintained library with a license file
- you need Promise/async-await based APIs
- targeting browsers without WebSQL support

## Facets
- artifact type: library
- maturity: abandoned
- function: orm, database, database-driver, search-engine, serialization
- domain: web-development, databases, frontend, backend, mobile-development
- platform: browser, cross-platform
