fs-copy-file-sync provides synchronous file copying functionality. It's a tiny, dependency-free module ideal for scenarios where blocking operations are acceptable or preferred. It mirrors the behavior of fs.copyFileSync but offers broader Node.js version compatibility by including a polyfill approach from Node version 8.5 if needed. This simple module ensures reliable and consistent file copying without external dependencies. It excels in situations requiring a no-frills, synchronous file duplication.
