normwerk

normwerk is a regulatory compliance layer for e-commerce on Medusa v2 and Vendure — the data and documents your regulator requires, built as thin, open-source adapters on top of a small, well-tested TypeScript core. Every product checks what it produces against the official tooling for its domain, not a reimplementation of it — and writes down what that tooling cannot check. Details: how we verify.
