Composable instrumentation in the Component Model | WebAssembly Unleashed

Debugging is where real engineering happens, and WebAssembly is reaching the point where “you can instrument it” isn’t good enough. In this episode of WebAssembly Unleashed, Joel Moses and Oscar Spencer sit down with Elizabeth Gilbert, a PhD candidate at Carnegie Mellon, to talk about Whamm: a DSL and framework designed to make instrumentation in Wasm less of a one-off engineering project and more of a repeatable, portable capability.

Elizabeth explains how she arrived at WebAssembly through the developer tooling and fault-injection world, and why existing instrumentation approaches in Wasm…
