eslint-plugin-require-path-exists is an ESLint plugin that checks whether paths in `require()` and `import` statements exist as files, preventing broken imports in CommonJS and ES6 applications. It supports webpack aliases, custom file extensions, and works seamlessly with the `linter-eslint` package in Atom. This tool is ideal for developers working on Node.js or webpack-based projects who want to enforce import path validation during development.
