When we set out to support Next.js applications on HarperDB, we quickly discovered that the path from next dev to a production-ready hosting solution was far from straightforward. This talk dives deep into the architectural decisions, technical challenges, and engineering solutions that went into building a flexible, scalable Next.js hosting platform. You'll learn how we tackled version compatibility (going back as far as Next.js v9!), engineered for scalability using worker threads, and all the meanwhile maintained local development experience parity. Whether you're considering self-hosting Next.js applications or interested in advanced deployment architectures, this session will equip you with practical insights and battle-tested strategies.
