unified-args streamlines command-line argument parsing for Node.js applications. It leverages a unified configuration object to define arguments, their types, and associated validation rules, simplifying the process of handling user input. The package supports both synchronous and asynchronous validation, allowing for flexible integration into various application architectures. It reduces boilerplate code traditionally needed for argument parsing, improving code maintainability and developer productivity. It's suitable for building CLIs with clear and concise input configuration.
