eslint-plugin-mdx

ESLint plugin and parser for MDX (Markdown with JSX), allowing linting of JavaScript/TypeScript syntax within MDX files. Current stable version is 3.7.0, with active maintenance and support for ESLint 10. It ships TypeScript types, supports both classic and flat ESLint configs, and can lint code blocks in MDX. Key differentiators include integration with remark-lint plugins, support for eslint-plugin-import and eslint-plugin-prettier, and a dedicated VSCode extension. Release cadence is monthly with minor and patch releases following Semantic Versioning.
