eslint-plugin-istanbul

ESLint plugin providing rules to enforce best practices for istanbul code coverage comments. Current stable version 0.1.2, low release cadence (last release 2020). Key differentiators: specifically targets istanbul ignore comments (no-ignore-file, prefer-ignore-reason) to maintain code quality in coverage exclusions. Requires ESLint 6.x or 7.x (not compatible with ESLint 8+/9+). Lightweight, no runtime dependencies beyond ESLint peer dependency.
