The **find‑in‑files** package provides a lightweight Node.js API for recursively searching text patterns (plain strings or regular expressions) across files in a given directory, optionally filtered by a filename regex. It offers both asynchronous (`find`) and synchronous (`findSync`) functions that return a promise‑resolved results object describing each matching file, the matching strings, their count, and the containing lines—making it useful for developers who need a simple, programmatic “grep‑like” utility in JavaScript projects.
