wait-on is a cross-platform command-line tool and Node.js API that pauses until files, network ports, sockets, or HTTP(S) resources become available or unavailable. Developers use it to coordinate builds, tests, and services by waiting for prerequisites to be ready or for services to shut down. Catalogue add-ons provide ways for coding agents to use or configure wait-on workflows.
