travis-deploy-once is a small Node‑JS utility for Travis CI that lets you run a deployment (or any script) only once when a build matrix contains multiple jobs (e.g., different Node versions or OSes). It determines a single “build leader” job—by default the one using the highest Node version—and returns success only if that job and all other matrix jobs pass, providing both a CLI and a programmatic API. The tool is aimed at developers who need to coordinate a single release step across a multi‑environment test suite.
