The `eslint-config-sanity` package provides a set of pre‑configured ESLint rule sets that Sanity.io uses across its own JavaScript, React, and TypeScript projects. By installing the package (and the required peer plugin dependencies) and extending `sanity`, `sanity/react`, or `sanity/typescript` in an `.eslintrc`, developers can quickly enforce Sanity’s coding standards in their own Node, browser, or front‑end applications. It’s intended for developers building or maintaining Sanity‑related codebases who want a ready‑made, opinionated linting configuration.
