Golem and the WASM Component Model
summary
Golem runs arbitrary WebAssembly workers persistently and claims end-to-end statically typed worker-to-worker calls by building on the WASM Component Model. It uses a Rust crate to fully reconstruct component interfaces, generates component stubs that wrap a generic wasm RPC/vrpc library, composes those stubs into worker bundles, and exposes a CLI that automates generation and composition. The pipeline is implemented, open source, and demonstrated working inside Golem to eliminate JSON-over-HTTP hops and preserve type safety.
