## What it is
TaffyDB is an open-source JavaScript library providing in-memory database capabilities for browser and Node.js applications. It lets you treat arrays of JSON objects like database tables and query or manipulate them with a SQL-inspired interface.

## Use cases
- query arrays of JSON objects with SQL-like filters in the browser
- filter, sort, and update in-memory records without a backend database
- find records by field equality, comparison operators, or like patterns
- get distinct values, counts, and selected columns from a collection
- manipulate client-side data collections in a jQuery or DOM app
- store and query structured data in a Node.js script

## When to choose
- you need lightweight in-memory querying of JSON data in the browser or Node
- you want SQL-inspired operations (insert, update, sort, distinct) on object arrays
- you need a small, dependency-free library compatible with older browsers

## When to avoid
- you need persistent storage, transactions, or large datasets beyond memory
- you need a real database with indexes, joins, or concurrent access
- the project requires actively maintained software with modern ES module support

## Facets
- artifact type: library
- maturity: maintenance
- function: database, search-engine, serialization
- domain: databases, web-development, developer-tools
- platform: browser, cross-platform
- tags: in-memory-database, -database, sql-like-queries, data-manipulation, javascript, nodejs
