The **run‑with‑ganache** package is a small Node.js utility that launches a Ganache (Ethereum‑compatible blockchain) instance in the background, runs a single shell command (e.g., Truffle tests or migrations), and then shuts Ganache down automatically. It’s aimed at developers working with Ethereum smart contracts who need a convenient, scriptable way to execute test or deployment commands against a temporary Ganache node without manually managing its lifecycle.
