Wasm Components: The Interchangeable Parts of Software
summary
Wasm components let application logic compile to small actor modules that wire to runtime-provided pieces: the demo replaces a bulky wasmbus RPC dependency with WIT interface files and a few thin imports so a 42-line HTTP+counter example no longer bundles storage code. Tooling currently glues modules with cargo-component, wit-bindgen and wasm-tools compose, runtime support today requires wasmtime, and providers can be swapped or even hot-swap components without recompiling the actor.
