yargs-patterns

What problem does it solve?

This Skill helps developers build robust Node.js CLIs using the yargs library by providing ready-to-use patterns for commands, options, middleware, and validation, reducing boilerplate and speeding up delivery.

Core Features & Use Cases

• Subcommands and namespace options: Create multi-command CLIs with isolated option spaces for each command.
• Options, flags, and validation: Define type coercion, defaults, and validation rules to catch errors early.
• Middleware and hooks: Preprocess arguments, load configs, and modify argv before command handlers run.
• Templates & Examples: Scaffold CLIs quickly with templates like basic-cli.js and advanced-cli.js, plus example subcommands.

Quick Start

Use the yargs-patterns skill to scaffold a new CLI by starting from the templates in templates/ and adapting the provided examples (such as subcommands-example.js) to your project. Then run the CLI and verify help and subcommand behavior.
