esmoduleserve is a lightweight HTTP shim that lets you run native ES‑module scripts in the browser without a bundling step. It serves a directory’s files normally but adds a special `/_m/` (or configurable) endpoint that rewrites import and re‑export statements to resolved, precise URLs using Node’s module‑resolution algorithm, optionally exposing parent directories. It’s aimed at web developers who want fast, zero‑config module loading for prototypes or small projects.
