eslint-config-standardize is a customizable ESLint configuration based on StandardJS rules and PrettierX formatting, designed for JavaScript and TypeScript projects. It includes plugins for React, Preact, and other tools, offering a more strict and opinionated setup than StandardJS. The project is ideal for developers seeking a comprehensive and modern linting solution, though it's noted that the author now recommends using their newer package, @quitsmx/eslint-config, as this one will be discontinued.
