The **JavaScript Basic Route Matcher** is a lightweight utility that creates functions for parsing URLs into parameter objects and for building URLs from data, with optional per‑parameter validation. It works in both Node.js and browsers and is intended to be embedded into larger routing libraries, providing simple pattern syntax (e.g., `"user/:id"`), regex‑based routes, and bidirectional `parse`/`stringify` methods. It’s aimed at developers needing a minimal, plug‑in‑ready router component for web applications.
