Next generation microservices and serverless apps with WebAssembly & Spin
summary
WebAssembly plus the open source Spin framework compiles Rust and TypeScript into tiny portable modules (example sizes: Rust wasm ~2 MB JIT / 300 KB AOT; Spin HTTP app JIT ~2.3 MB, AOT ~1.1 MB), starts in under a millisecond, and runs serverless locally or in the cloud. Demo builds a front end plus two backends with SQLite and key‑value store persistence, deploys to cloud successfully with a visible cold start request, and runs on Kubernetes via runwasi using the spin CLI and spin watch/build.
