wait-on: Resource Readiness Utility

wait-on is a robust, cross-platform utility available as both a command-line interface (CLI) and a Node.js programmatic API, designed to pause execution until specified resources become available or unavailable. Its current stable version is 9.0.5, with minor patch releases addressing dependency updates and bug fixes, while major versions primarily align with Node.js LTS lifecycle. It differentiates itself by supporting a wide array of resource types including local files, TCP ports, Unix domain sockets, and HTTP(s) endpoints, with advanced features like waiting for files to stop growing (useful for build processes) and a 'reverse mode' to await resource unavailability. This makes it particularly suited for orchestrating tasks in CI/CD pipelines, development environments, and service startup/shutdown sequences where precise timing and resource readiness are crucial.
