How to Query Components

Basic Component Query

"Show me the shadcn button component"
"Get the shadcn card component"
"What's the shadcn dialog component?"

Framework-Specific Query

"Show me the shadcn button for React"
"Get the shadcn card for Svelte"
"What's the shadcn select for Vue?"

Block Query

"Show me the shadcn dashboard block"
"Get the shadcn form block"
"What blocks are available in shadcn?"

Metadata Query

"What dependencies does shadcn select need?"
"How do I install the shadcn button?"
"What peer dependencies does shadcn dialog require?"

Multi-Framework Support

One of shadcn-ui's unique advantages: same component logic, different framework implementations.

Component Categories

Form Components

• Button, Input, Textarea
• Select, Checkbox, Radio Group
• Switch, Slider
• Form, Label
• Date Picker, Calendar

Layout Components

• Card, Separator
• Accordion, Tabs
• Sheet, Dialog, Drawer
• Collapsible, Resizable

Navigation

• Navigation Menu, Breadcrumb
• Dropdown Menu, Context Menu
• Command, Menubar

Feedback

• Alert, Toast, Progress
• Skeleton, Badge
• Alert Dialog

Data Display

• Table, Data Table
• Avatar, Tooltip
• Hover Card, Popover

Usage Workflow

1. Query for Component

User: "Show me the shadcn button component"

2. Review Component Details

You'll get:

• TypeScript source code
• Component props and variants
• Usage examples
• Dependencies required
• Configuration needed

3. Implement and Customize

• Copy base component structure
• Apply your own styling/theming
• Customize variants as needed
• Add project-specific logic

Example: Building a Dashboard

Step 1: Query Blocks

"Show me the shadcn dashboard block"

What you get:

• Complete dashboard layout
• Pre-configured components (cards, tables, charts)
• Navigation structure
• Responsive grid system

Step 2: Query Individual Components

"Show me shadcn card component"
"Show me shadcn table component"

Step 3: Customize

• Apply your design system colors
• Modify typography
• Adjust spacing and layout
• Add custom functionality

Dependencies and Installation

Check Dependencies

"What dependencies does the shadcn select component need?"

Response includes:

• Required packages (@radix-ui/react-select, etc.)
• Peer dependencies (React, Tailwind CSS)
• Installation commands
• Configuration requirements

Common Dependencies

Most shadcn components require:

• React 18+ (for React version)
• Tailwind CSS 3+
• Radix UI primitives
• class-variance-authority
• clsx, tailwind-merge

Best Practices

✅ DO

1. Use as Foundation

   • shadcn provides structure and accessibility
   • Build your unique design on top

2. Query Before Building

   • Check if shadcn has a component before building from scratch
   • Save time on accessibility and edge cases

3. Check Multiple Frameworks

   • If switching frameworks, query for that implementation
   • Maintain consistent UX across platforms

4. Use Blocks for Rapid Prototyping

   • Dashboard, form, calendar blocks save hours
   • Customize blocks to match your brand

5. Review Metadata

   • Check dependencies before installing
   • Understand peer dependencies and conflicts

❌ DON'T

1. Don't Use Components As-Is in Production

   • Always customize to match your design system
   • Add brand colors, typography, spacing

2. Don't Skip Accessibility Review

   • shadcn provides accessible foundations
   • Don't break them with aggressive customizations

3. Don't Mix Framework Implementations

   • Stick to one framework per project
   • Cross-framework mixing causes conflicts

4. Don't Ignore Dependencies

   • Review required packages before installation
   • Check for version conflicts with existing dependencies
