A high-performance storage architecture featuring Direct Cloudflare R2 Presigned S3 uploads, 5MB binary chunked resumable transfers with simulated network interruption recovery, and asynchronous media transformation workers that save up to 82% bandwidth.
App servers never become memory bottlenecks. React Router server issues cryptographic presigned PUT URLs, allowing clients to stream raw binaries directly to Cloudflare R2 at full line speed.
Files are partitioned into 5MB chunks with SHA-256 integrity verification. Test connection drops with the interactive simulator and watch uploads seamlessly auto-resume from the last byte offset.
Automated background queue pipeline handles lossy/lossless WebP encoding, next-gen AVIF compression, multi-size responsive thumbnails, and Blurhash strings saving 70%+ bandwidth.
Designed for high concurrency, zero web server memory bottlenecks, and automated network disconnect recovery.
Client requests authenticated S3 PUT URL from React Router server. Zero file bytes pass through web server.
Large files are split into 5MB chunks. Each chunk is streamed directly to Cloudflare R2 bucket with checksum verification.
Each uploaded chunk index is committed to PostgreSQL Neon. If connection drops, transfers resume without restarting.
On upload completion, background workers generate WebP/AVIF conversions (-74% bandwidth) and multi-scale srcset thumbnails.
