log4js‑api is a thin compatibility layer that lets library authors depend on a generic Log4js interface without tying their code to a specific Log4js version. It simply re‑exports `getLogger` (returning a logger with the standard trace/debug/info/warn/error/fatal methods) and forwards calls to the real Log4js implementation if it is present, otherwise acting as a no‑op. This package is aimed at developers building other Node.js libraries who want optional, version‑agnostic logging support.
