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
