Recursive Directory Creation Utility

mk-dirs is a minimalistic, Promise-based utility designed for recursively creating directories in Node.js, functioning as an `mkdir -p` equivalent. Currently stable at version 3.0.0, it differentiates itself by being exceptionally lightweight (381B to 419B gzipped) and having zero external dependencies, offering a faster alternative to packages like `mkdirp` and `make-dir`. It provides both an asynchronous (default) and a synchronous opt-in mode, catering to different application needs and Node.js versions (>=8.x for async, >=6.x for sync). While Node.js v10.12.0+ includes native `fs.mkdir` with a `recursive` option, `mk-dirs` maintains its value through a consistent, promise-based API and `cwd` option. Its release cadence is not explicitly stated but typically follows a "release when needed" pattern for such focused utilities.
