Version Details and Security Vulnerabilities

Eslint-config-eslint offers a standardized ESLint configuration tailored specifically for projects developing ESLint itself, promoting consistent code style and quality within the ESLint ecosystem. Comparing versions 5.0.0 and 4.0.0 reveals key updates for developers. Version 5.0.0, released in July 2018, introduces a peer dependency: eslint-plugin-node with a version constraint of "^6.0.1". This signifies that projects utilizing eslint-config-eslint version 5.0.0 should also include eslint-plugin-node version 6.0.1 or higher to ensure compatibility and access to the plugin's rules and functionalities. This plugin typically offers rules specific to Node.js environments.

While both versions share the core js-yaml dependency and maintain the same core metadata (description, license, repository, and author), the inclusion of a peer dependency represents a significant change in how the configuration interacts with the larger ESLint environment. Developers upgrading to version 5.0.0 must ensure they install eslint-plugin-node to avoid potential errors or unexpected behavior. Furthermore, version 5.0.0 includes fileCount and unpackedSize in the dist object, which give more insights on the package content itself. The earlier 4.0.0 version, released in February 2017, lacks this peer dependency, offering a more basic and potentially less environment-aware configuration that works specifically for javascript linting without needing a specific plugin. Developers should consider their project's needs and target environment when choosing between these versions, prioritizing the newer v5 if Node.js-specific linting is desired and the eslint-plugin-node peer dependency is acceptable.
