GraphQL at the Edge with WebAssembly

on YouTube ↗37m

" summary

A Rust GraphQL server is compiled to WebAssembly and trimmed to a ~950KB runtime so it fits Cloudflare Workers; pure computation (parsing, IR, query-to-SQL mapping) runs unchanged but networking needs platform-specific glue using the Worker socket API and a JS async bridge. Connection latency drops from ~300ms to ~100ms with hyperdrive pooling; build uses wasm-bindgen, optimizes with wasm-opt/wasm-gc, and targets wasi preview2.
