Building a High-Performance SQLite Edge Replica with Turso and Fly.io
2025-02-13

This tutorial demonstrates how to build custom SQLite edge replicas for Turso using Node.js and Fly.io to boost database performance. By deploying proxy servers across multiple global regions and leveraging Fly.io's Anycast network, low-latency data access is achieved. The solution caches data locally in a SQLite file, periodically syncing with the primary database, reducing network latency and data replication costs for a superior user experience. The tutorial covers Dockerfile configuration, Fly.io deployment, proxy server implementation details, and includes a security authentication mechanism.
