AlaSQL is a lightweight in-memory SQL database written in pure JavaScript that runs in the browser, Node.js, and mobile apps. It queries both relational tables and nested JSON data, and supports importing/exporting data from formats like localStorage, IndexedDB, and Excel.

Use cases

run SQL queries on JSON data in the browser
in-memory data processing for BI dashboards on fat clients
import and export Excel/CSV data with SQL
ETL and data manipulation in Node.js
persist query results to localStorage or IndexedDB
query nested NoSQL-style JSON with SQL joins and grouping

When to choose

you need fast client-side SQL over in-memory relational or JSON data
you want easy import/export across Excel, CSV, localStorage, and IndexedDB
you're building browser or Node.js apps needing a lightweight embedded SQL engine

When to avoid

you need durable multi-user server-side storage or full ACID transactions
you need very limited transaction support or concurrent writes
you need a production-grade database backend like PostgreSQL or SQLite
