Building a Production-Ready File Download System with GoFrame
- The article explores building a production-ready file download system with GoFrame, covering basic implementation, handling large files, resume support, security measures, and optimization for production.
- GoFrame is chosen for its stream-based processing, middleware support, clean error handling, and progress tracking capabilities.
- Security measures are emphasized, including validating file paths, checking permissions, limiting file types, and implementing robust validation functions.
- Handling large files efficiently without memory issues is achieved through streaming implementations in chunks.
- Resume support is discussed to handle failed downloads, especially for large files, by implementing range requests.
- Real-world scenarios like handling different file types, browser compatibility, and download progress monitoring are addressed with practical examples.
- Production tips include rate limiting, caching, monitoring metrics, implementing circuit breakers, and graceful shutdowns for robust file download services.
- Advanced features like zip downloads on the fly, cloud storage integration, and download queue implementation are detailed for more complex requirements.
- Comprehensive error handling patterns, specific use case examples like video streaming, large Excel file generation, and PDF generation are provided to handle various scenarios.
- Common gotchas to avoid like memory leaks, security issues, and performance problems are highlighted to ensure a smooth file download experience.
