## What it is
NeDB is a pure-JavaScript embedded database for Node.js, Electron, nw.js, and the browser, offering persistent or in-memory storage with an API that is a subset of MongoDB's. It requires no binary dependencies and stores data in files or memory.

## Use cases
- embed a lightweight nosql database in an electron app
- store  documents locally in node.js without a database server
- use a mongodb-like query api in the browser
- prototype apps with a simple file-based datastore
- add persistent storage to nw.js desktop apps

## When to choose
- you need an embedded, zero-dependency database with MongoDB-style queries
- you're building a small Electron or browser app needing local persistence
- you want a simple datastore for prototyping or small datasets

## When to avoid
- you need a maintained library with security fixes - the project is explicitly unmaintained
- you need high concurrency, replication, or large-scale production workloads
- you need full MongoDB feature coverage

## Facets
- artifact type: library
- maturity: abandoned
- function: database, serialization
- domain: databases, developer-tools, web-development
- platform: browser, cross-platform
- tags: embedded-database, mongodb-like-api, nosql, electron, in-memory-database, javascript, nodejs
