Node‑fixturify is a lightweight library that lets you serialize and deserialize arbitrary JSON objects to and from directory‑based file system structures, making it easy to create, read, and modify mock file hierarchies in code. It’s aimed at developers—particularly test writers—who need a simple, synchronous way to generate temporary file layouts for unit or integration testing. The API supports glob patterns, ignoring files, and removal of empty directories while handling UTF‑8‑encoded text files.
