Minimongo is a client-side in-memory MongoDB clone for JavaScript/TypeScript with pluggable storage backends (Memory, LocalStorage, IndexedDB, WebSQL, SQLite). It supports hybrid local/remote synchronization over HTTP, replication, EJSON, and geospatial queries.

Use cases

• offline-first web app with local database and server sync
• query client-side data with MongoDB-like syntax
• cache server data in the browser with IndexedDB
• sync pending local edits to a REST API
• run geospatial queries like $near in the browser
• replicate data between local and remote database instances

When to choose

• you want a MongoDB-style query API entirely client-side
• you need offline persistence with automatic sync to a server
• you want multiple swappable storage backends (memory, IndexedDB, WebSQL, SQLite)
• you need geospatial queries ($near, $geoIntersects) in the browser

When to avoid

• you need a full MongoDB server with server-side aggregation pipelines
• you need multi-user real-time conflict resolution beyond simple base-document resolution
• you are not using JavaScript/TypeScript in a browser or Node environment
