The **require‑overrides** package provides a tiny CommonJS utility that lets developers transparently replace (or “alias”) one module with another—typically a server‑side rendering (SSR) version—by defining overrides that are applied at `require` time. It is geared toward Node.js projects that need to switch between client‑ and server‑specific implementations (e.g., swapping `uhtml` for `uhtml‑ssr`) without changing import statements, and also offers a callback API for bulk or dynamic mappings, with a brief guide for similar behavior in ESM via import‑maps.
