ESLint is Now Language-Agnostic: Linting JSON, Markdown, and...
Blog post from Socket
ESLint has evolved into a language-agnostic linting tool by introducing support for JSON and Markdown through officially-supported plugins, marking a significant expansion beyond its original JavaScript focus. This development follows a strategic refactoring of ESLint's core to separate JavaScript-specific elements from language-agnostic components, allowing for a more unified linting experience across different programming languages and file formats. The new plugins, @eslint/json and @eslint/markdown, can be installed from npm and enable users to create custom rules, enhancing error detection and consistency in JSON and Markdown files. ESLint's Technical Steering Committee initiated this shift to accommodate requests for broader language support, starting with JSON and Markdown due to their widespread use and demand, and plans to extend support to YAML and CSS in the future. This transformation aims to establish ESLint as a universal linter capable of handling various file types, leveraging both official and community-developed plugins to tap into diverse expertise across different ecosystems.
