Doing Server Side WebAssembly the Hard Way

Explore the challenges and solutions of implementing server-side WebAssembly in this conference talk by Liam Crilly from NGINX. Discover how the NGINX Unit team tackled the complexities of connecting HTTP server implementation with Wasmtime, navigating the intricacies of direct memory access and low-level languages. Learn about the hurdles faced in carrying HTTP metadata in and out of the Wasm runtime, and the team's journey to overcome these obstacles. Gain insights into the lessons learned about server-side WebAssembly and understand how the WASI HTTP project aims to address similar issues, potentially combining HTTP scalability with WebAssembly's performance and portability.
