A lightweight, zero-setup JSON database with SQL-like queries, perfect for rapid development. LazyDB mimics SQLite’s functionality but works directly with JSON files or in-memory, requiring no installation.
- File-Based or In-Memory Storage: Use
database.jsonor run in-memory. - SQL-like Queries:
db.select('users').where('age', '>', 20).join('orders', 'id', 'userId'). - Advanced Features: Joins, aggregations (
count,sum,avg,min,max), full-text search. - Indexing: B-tree for speed, inverted index for text search.
- Zero-Config:
new LazyDB()for in-memory mode. - Event-Driven: React to inserts, updates, and deletes.
- CLI:
npx lazydb "SELECT * FROM users WHERE age > 20". - REST API: Integrate with Express.js.
- Cross-Platform: Works in Node.js, browsers, and Deno.
