Patterns, extensions, and real-world examples for using SQLite as your only database.
Stop spinning up expensive Postgres instances and Redis clusters for an app with 1,000 DAU. The SQLite renaissance is here.
SQLite for Everything is a manifesto and practical codebase demonstrating how to use SQLite for session management, queueing, caching, full-text search, and relational data—all in a single file on disk, supporting tens of thousands of concurrent users.
WAL Mode&PRAGMAoptimizations: 10x your concurrent write throughput.- SQLite as Redis: Implementing TTL caching and fast KV stores using JSON1 extensions.
- SQLite as a Vector DB: Using
sqlite-vssfor local similarity search and AI applications. - SQLite as a Message Queue: Building robust background task workers relying entirely on SQLite locking mechanisms.
- Backup & Replication: Real-world examples of integration with LiteFS and Turso.
All examples are provided in Node.js (better-sqlite3) and Python (sqlite3), featuring fully commented code indicating where optimizations matter most. View the examples/ directory to get started.
