Wasm Components for Every Language
Talkat WasmCon 2023 · on Wednesday, 2023-09-06· at 15:45· Grand Ballroom F, Hyatt Regency Bellevue, 900 Bellevue Way NE·
summary
Argues WebAssembly can be componentized from compiled and runtime languages and shows working tooling and a demo that composes eight language components (WAT, C, Rust, JavaScript, Python, etc.) into one call stack. Uses wit-bindgen and generated type info with wasm-tools component new to wrap AOT modules, and shows runtime wrapping via componentized JS and componentize-py with snapshotting. Demonstrates a browser drag‑and‑drop wasm-builder that produces a composed component and a Wasmtime‑based runner that executes the full polyglot stack.
