eslint-plugin-github

An opinionated collection of ESLint shared configs and rules used by GitHub. Current stable version is 6.0.0, which includes flat config support and ESM-only. The package provides configs for browser, React, TypeScript, and internal GitHub applications. Key differentiators: it enforces GitHub's own coding standards, includes accessibility rules (a11y), async/await best practices, and actionable rules like array-foreach and no-then. It supports both legacy .eslintrc and flat config via getFlatConfigs().
