Component Development

1. Core Principles

• Library First: Shared components live in libs/ui.
• Strict Separation: libs/ui CANNOT depend on apps/nextblock. It must remain publishable as a standalone package.
• Tech Stack: React, Tailwind CSS, Radix UI, Lucide React.

2. Directory Structure (libs/ui)

• src/lib/: All UI components — both base Shadcn/UI components (Button, Input, etc.) and custom complex components live here as flat files.
• src/styles/globals.css: Tailwind configuration and global styles.
• src/styles/: Additional CSS files (theme, typography, animations, base, components).

3. Workflow

Creating a new component

1. Shared Component:
   • Create in libs/ui/src/lib/<Name>.tsx.
   • Export from libs/ui/src/index.ts.
   • Use nx lint ui to verify.
2. App-Specific Component:
   • Create in apps/nextblock/components/.
   • Only do this if the component is tightly coupled to Next.js features (like cookies, headers, or specific app logic).

Styling

• Use className with Tailwind utility classes.
• Use cn() utility from @nextblock-cms/utils for conditional class merging.
• Do not use CSS modules or styled-components unless absolutely necessary.

4. Best Practices

• Client Components: Add 'use client' at the top if using hooks (useState, useEffect) or event listeners.
• Accessibility: Use Radix UI primitives where possible to ensure a11y compliance.
