Add Package to Workspace

Add and configure new project dependencies: $ARGUMENTS

Instructions

1. Package Definition and Analysis

   • Parse package name and type from arguments: $ARGUMENTS (format: name [type])
   • If no arguments provided, prompt for package name and type
   • Validate package name follows workspace naming conventions
   • Determine package type: library, application, tool, shared, service, component-library
   • Check for naming conflicts with existing packages

2. Package Structure Creation

   • Create package directory in appropriate workspace location (packages/, apps/, libs/)
   • Set up standard package directory structure based on type:
     • src/ for source code
     • tests/ or __tests__/ for testing
     • docs/ for package documentation
     • examples/ for usage examples (if library)
     • public/ for static assets (if application)
   • Create package-specific configuration files

3. Package Configuration Setup

   • Generate package.json with proper metadata:
     • Name following workspace conventions
     • Version aligned with workspace strategy
     • Dependencies and devDependencies
     • Scripts for build, test, lint, dev
     • Entry points and exports configuration
   • Configure TypeScript (tsconfig.json) extending workspace settings
   • Set up package-specific linting and formatting rules

4. Package Type-Specific Setup

   • Library: Configure build system, export definitions, API documentation
   • Application: Set up routing, environment configuration, build optimization
   • Tool: Configure CLI setup, binary exports, command definitions
   • Shared: Set up common utilities, type definitions, shared constants
   • Service: Configure server setup, API routes, database connections
   • Component Library: Set up Storybook, component exports, styling system

5. Workspace Integration

   • Register package in workspace configuration (nx.json, lerna.json, etc.)
   • Configure package dependencies and peer dependencies
   • Set up cross-package imports and references
   • Configure workspace-wide build order and dependencies
   • Add package to workspace scripts and task runners

6. Development Environment

   • Configure package-specific development server (if applicable)
   • Set up hot reloading and watch mode
   • Configure debugging and source maps
   • Set up development proxy and API mocking (if needed)
   • Configure environment variable management

7. Testing Infrastructure

   • Set up testing framework configuration for the package
   • Create initial test files and examples
   • Configure test coverage reporting
   • Set up package-specific test scripts
   • Configure integration testing with other workspace packages

8. Build and Deployment

   • Configure build system for the package type
   • Set up build artifacts and output directories
   • Configure bundling and optimization
   • Set up package publishing configuration (if library)
   • Configure deployment scripts (if application)

9. Documentation and Examples

   • Create package README with installation and usage instructions
   • Set up API documentation generation
   • Create usage examples and demos
   • Document package architecture and design decisions
   • Add package to workspace documentation

10. Validation and Integration Testing

    • Verify package builds successfully
    • Test package installation and imports
    • Validate workspace dependency resolution
    • Test development workflow and hot reloading
    • Verify CI/CD pipeline includes new package
    • Test cross-package functionality and integration
