## What it is
ZangoDB is a MongoDB-like interface for HTML5 IndexedDB in the browser, supporting familiar filtering, projection, sorting, updating, and aggregation operators. It lets client-side JavaScript code query browser-local storage with MongoDB-style syntax.

## Use cases
- store and query data offline in the browser
- use MongoDB query syntax with IndexedDB
- run aggregations on client-side data
- build offline-first web apps with local storage
- filter, sort, and project documents in IndexedDB

## When to choose
- you want MongoDB-style queries over browser IndexedDB
- you need client-side offline data storage with rich querying
- you're building a browser app that already uses MongoDB on the server

## When to avoid
- you need a real server-side database
- you need full MongoDB feature coverage or recent updates
- you need a maintained library - the last release was in 2018

## Facets
- artifact type: library
- maturity: maintenance
- function: database, orm
- domain: databases, web-development, frontend
- platform: browser
- tags: indexeddb, mongodb-like, nosql, client-side-database, query-operators, aggregation, nodejs, javascript
