WebAssembly Beyond the Browser
Talkat JCON Europe 2023 · on Thursday, 2023-06-22· at 12:00· Cinema Blackbox, Im Mediapark 1, 50670 Köln, Germany·
summary
WebAssembly runs outside the browser today using runtimes like Wasmtime, WasmEdge and Wasmer, compiled from Rust, TinyGo and .NET into .wasm modules; demos show building Rust/Go/.NET binaries and running them in those runtimes and (via Docker’s new support) containerd shims. Claimed benefits are tens of milliseconds startup and modules typically 2–3x smaller than equivalent containers, but the current WASI spec is limited — notably no socket support in WASI preview1 — and frameworks such as Spin and WAGI add HTTP and plugin capabilities.
