The original title is "Building Vidiflow: A Production-Grade Video Downloader Backend in TypeScript"

Short summary

Detailed technical article on building a production-grade video downloader API in TypeScript using Node.js, Express, and PostgreSQL. Covers key architecture patterns: modular design, provider pattern for multi-platform support, JWT authentication, asynchronous job processing with BullMQ, and WebSocket real-time updates. Emphasizes designing for scalability through clean boundaries rather than premature optimization.

• •Modular architecture with separate auth, download, user, and provider modules for clean code organization and maintainability
• •Provider pattern enables easy extension to new video platforms without modifying core logic
• •Production patterns: JWT + refresh tokens, async job queues, WebSocket updates, typed error handling, and Swagger documentation
