The **data‑test‑api** package provides a lightweight Node.js library that builds a simple, type‑safe API for browsing, reading and filtering static test files bundled with a project. By pointing it at a directory (optionally with a custom filter), developers can retrieve files by relative path or name, get their contents as buffers or streams, and iterate over all entries—making it ideal for test suites, CI pipelines, or any tooling that needs consistent access to fixture data.
