The **@cfware/nyc** package supplies a pre‑configured set of Istanbul/nyc code‑coverage defaults that the author uses across his Node.js projects. It provides a chainable API (both as a class and via static helpers) for customizing common nyc options—such as enabling `all`, toggling coverage checks, adding includes/excludes, and setting reporters—so developers can quickly import a ready‑made, opinionated coverage configuration and extend it as needed.
