`eslint-plugin-wrapper` is a tool that allows developers to define custom ESLint rules directly within their project's configuration file, bypassing the need for separate plugin packages. It's particularly useful for organizations wanting to consolidate multiple ESLint plugins and configs into a single wrapper package, or for projects needing to cherry-pick specific rules from different versions of external plugins. This tool is designed for developers and teams looking to simplify their ESLint setup and maintain more control over their linting rules.
