Logging and Debugging + +```typescript +// Structured logging +import pino from 'pino'; + +const logger = pino({ + level: process.env.LOG_LEVEL || 'info', + transport: { + target: 'pino-pretty', + options: { + colorize: true, + }, + }, +}); + +// Log server lifecycle +server.onerror = (error) => { + logger.error({ error }, 'Server error'); +}; + +// Log tool calls +logger.info({ tool: name, args }, 'Tool called'); +``` + +### 4. Progress Notifications + +```typescript +// Report progress for long-running operations +import { CreateMessageRequestSchema } from '@modelcontextprotocol/sdk/types.js'; + +async function longOperation(server: Server) { + // Send progress updates + await server.sendNotification({ + method: 'notifications/progress', + params: { + progress: 0.25, + message: 'Processing step 1 of 4...', + }, + }); + + // Continue operation... + + await server.sendNotification({ + method: 'notifications/progress', + params: { + progress: 1.0, + message: 'Operation complete!', + }, + }); +} +``` + +## Testing Strategy + +### Unit Tests + +```typescript +// Test tool handlers +describe('ToolHandlers', () => { + it('should validate input parameters', async () => { + const result = await handleTool('example_tool', { + input: 'test' + });

Migration Guide + +## Overview +This guide covers migrating from the legacy Button component to the new shadcn/ui Button. + +## Breaking Changes + +### Prop Changes +- `variant="danger"` โ `variant="destructive"` +- `fullWidth` โ `className="w-full"` +- Removed `medium` size (use `default` instead) + +### Styling Changes +- CSS-in-JS โ Tailwind CSS classes +- Custom CSS properties no longer supported +- Use `className` prop for customization + +## Migration Steps + +1. **Update imports** + ```tsx + // Old + import { Button } from '@/components/legacy/Button' + + // New + import { Button } from '@/components/ui/button' + ``` + +2. **Update prop usage** + ```tsx + // Old + <Button variant="danger" fullWidth>Delete</Button> + + // New + <Button variant="destructive" className="w-full">Delete</Button> + ``` + +3. **Update custom styling** + ```tsx + // Old + <Button style={{ backgroundColor: 'custom' }}>Custom</Button> + + // New + <Button className="bg-custom-color">Custom</Button> + ``` + +## Compatibility Layer +For gradual migration, use the compatibility wrapper: + +```tsx +import { LegacyButtonCompat as Button } from '@/components/ui/button' +// No changes needed to existing code +``` +``` + +## Best Practices + +1. **Plan Incrementally** + - Start with leaf components + - Test thoroughly at each step + - Maintain backward compatibility during transition + - Use feature flags for gradual rollout + +2. **Automated Testing** + - Create visual regression tests + - Test all prop combinations + - Verify accessibility compliance + - Performance test before/after + +3. **Documentation** + - Document all breaking changes + - Provide migration examples + - Create comparison guides + - Update team knowledge base + +4. **Communication** + - Announce migration plans early + - Provide training sessions + - Create migration timelines + - Support team members during transition + +Remember: Successful migrations prioritize stability and user experience over speed!

tokens together + - Version your design tokens + +2. **Color Accessibility** + - Test contrast ratios for all color combinations + - Ensure colors work for colorblind users + - Don't rely solely on color to convey information + - Provide sufficient contrast in both themes + +3. **Performance Optimization** + - Use CSS custom properties for runtime changes + - Avoid inline styles for theme values + - Minimize CSS-in-JS overhead + - Cache theme calculations + +4. **Developer Experience** + - Provide TypeScript types for theme tokens + - Include theme documentation + - Create theme development tools + - Maintain consistent API patterns + +Remember: Great themes are invisible to users but make everything feel cohesive and professional!

Copy-Paste Architecture + +- **No npm package** - Components are copied into your project +- **Full ownership** - The code is yours to modify +- **Direct customization** - Edit components directly +- **No abstraction layers** - See exactly what's happening + +### 2. Component Anatomy + +Every component follows this structure: + +```tsx +// Root component with forwardRef +const Component = React.forwardRef<HTMLElement, ComponentProps>( + ({ className, variant, size, asChild = false, ...props }, ref) => { + const Comp = asChild ?

Variant System with CVA + +```tsx +import { cva, type VariantProps } from "class-variance-authority" + +const buttonVariants = cva( + "inline-flex items-center justify-center whitespace-nowrap rounded-md text-sm font-medium transition-colors focus-visible:outline-none focus-visible:ring-1 focus-visible:ring-ring disabled:pointer-events-none disabled:opacity-50", + { + variants: { + variant: { + default: "bg-primary text-primary-foreground shadow hover:bg-primary/90", + destructive: "bg-destructive text-destructive-foreground shadow-sm hover:bg-destructive/90", + outline: "border border-input bg-background shadow-sm hover:bg-accent hover:text-accent-foreground", + secondary: "bg-secondary text-secondary-foreground shadow-sm hover:bg-secondary/80", + ghost: "hover:bg-accent hover:text-accent-foreground", + link: "text-primary underline-offset-4 hover:underline", + }, + size: { + default: "h-9 px-4 py-2", + sm: "h-8 rounded-md px-3 text-xs", + lg: "h-10 rounded-md px-8", + icon: "h-9 w-9", + }, + }, + defaultVariants: { + variant: "default", + size: "default", + }, + } +) +``` + +### 2. Polymorphic Components with asChild + +```tsx +import { Slot } from "@radix-ui/react-slot" + +interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> { + asChild?: boolean +} + +const Button = React.forwardRef<HTMLButtonElement, ButtonProps>( + ({ className, asChild = false, ...props }, ref) => { + const Comp = asChild ? Slot : "button" + return <Comp ref={ref} className={cn(...)} {...props} /> + } +) +``` + +### 3. Controlled/Uncontrolled Pattern + +```tsx +// Controlled +<Select value={value} onValueChange={setValue}> + <SelectTrigger>...</SelectTrigger> + <SelectContent>...</SelectContent> +</Select> + +// Uncontrolled +<Select defaultValue="apple"> + <SelectTrigger>...</SelectTrigger> + <SelectContent>...</SelectContent> +</Select> +``` + +### 4. Form Integration with React Hook Form + +```tsx +<Form {...form}> + <FormField + control={form.control} + name="email" + render={({ field }) => ( + <FormItem> + <FormLabel>Email</FormLabel> + <FormControl> + <Input placeholder="email@example.com" {...field} /> + </FormControl> + <FormDescription> + Enter your email address + </FormDescription> + <FormMessage /> + </FormItem> + )} + /> +</Form> +``` + +## Theming System + +### CSS Variables Structure + +```css +@layer base { + :root { + --background: 0 0% 100%; + --foreground: 222.2 84% 4.9%; + --card: 0 0% 100%; + --card-foreground: 222.2 84% 4.9%; + --popover: 0 0% 100%; + --popover-foreground: 222.2 84% 4.9%; + --primary: 222.2 47.4% 11.2%; + --primary-foreground: 210 40% 98%; + --secondary: 210 40% 96.1%; + --secondary-foreground: 222.2 47.4% 11.2%; + --muted: 210 40% 96.1%; + --muted-foreground: 215.4 16.3% 46.9%; + --accent: 210 40% 96.1%; + --accent-foreground: 222.2 47.4% 11.2%; + --destructive: 0 84.2% 60.2%; + --destructive-foreground: 210 40% 98%; + --border: 214.3 31.8% 91.4%; + --input: 214.3 31.8% 91.4%; + --ring: 222.2 84% 4.9%; + --radius: 0.5rem; + } + + .dark { + --background: 222.2 84% 4.9%; + --foreground: 210 40% 98%; + /* ... dark theme variables ... */ + } +} +``` + +### Color Convention + +- Each color has a **base** and **foreground** variant +- Base: Background color +- Foreground: Text color on that background +- Ensures proper contrast automatically + +## Accessibility Patterns + +### 1. ARIA Attributes + +```tsx +// Proper ARIA labeling +<Dialog> + <DialogTrigger asChild> + <Button>Open</Button> + </DialogTrigger> + <DialogContent> + <DialogHeader> + <DialogTitle>Title</DialogTitle> + <DialogDescription> + Description for screen readers + </DialogDescription> + </DialogHeader> + </DialogContent> +</Dialog> +``` + +### 2. Keyboard Navigation + +All components support: +- **Tab/Shift+Tab** - Focus navigation +- **Enter/Space** - Activation +- **Escape** - Close/cancel +- **Arrow keys** - List navigation +- **Home/End** - Boundary navigation + +### 3. Focus Management + +```tsx +// Visible focus indicators +className="focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2" + +// Focus trap in modals +<FocusTrap> + <DialogContent>...</DialogContent> +</FocusTrap> +``` + +## Data Display Patterns + +### 1. Tables with TanStack Table + +```tsx +const table = useReactTable({ + data, + columns, + getCoreRowModel: getCoreRowModel(), + getPaginationRowModel: getPaginationRowModel(), + getSortedRowModel: getSortedRowModel(), + getFilteredRowModel: getFilteredRowModel(), +}) + +<Table> + <TableHeader> + {table.getHeaderGroups().map((headerGroup) => ( + <TableRow key={headerGroup.id}> + {headerGroup.headers.map((header) => ( + <TableHead key={header.id}> + {flexRender(header.column.columnDef.header, header.getContext())} + </TableHead> + ))} + </TableRow> + ))} + </TableHeader> + <TableBody> + {table.getRowModel().rows.map((row) => ( + <TableRow key={row.id}> + {row.getVisibleCells().map((cell) => ( + <TableCell key={cell.id}> + {flexRender(cell.column.columnDef.cell, cell.getContext())} + </TableCell> + ))} + </TableRow> + ))} + </TableBody> +</Table> +``` + +### 2. Charts with Recharts + +```tsx +<ChartContainer config={chartConfig}> + <AreaChart data={data}> + <CartesianGrid strokeDasharray="3 3" /> + <XAxis dataKey="month" /> + <YAxis /> + <ChartTooltip /> + <Area + type="monotone" + dataKey="value" + stroke="hsl(var(--chart-1))" + fill="hsl(var(--chart-1))" + /> + </AreaChart> +</ChartContainer> +``` + +## Common Commands + +### Development + +```bash +# Initialize shadcn/ui +npx shadcn@latest init + +# Add components +npx shadcn@latest add button card dialog form + +# Add all components +npx shadcn@latest add --all + +# Update components +npx shadcn@latest add button --overwrite + +# Build custom registry +npx shadcn@latest build +``` + +### Component Development + +```bash +# Development server +npm run dev + +# Type checking +npm run type-check + +# Linting +npm run lint + +# Testing +npm run test + +# Build +npm run build +``` + +## Performance Optimization + +### 1. Bundle Size + +- Only import what you use +- Components are tree-shakeable +- No runtime overhead from library + +### 2. Code Splitting + +```tsx +// Lazy load heavy components +const HeavyChart = lazy(() => import('@/components/ui/chart')) + +<Suspense fallback={<Skeleton />}> + <HeavyChart /> +</Suspense> +``` + +### 3. Animation Performance + +```tsx +// Use CSS transforms for animations +className="transition-transform hover:scale-105" + +// Avoid layout shifts +className="transform-gpu" +``` + +## Testing Strategies + +### 1.

Use unprefixed classes for mobile base styles + - Add complexity with larger breakpoint prefixes + - Test on actual devices, not just browser dev tools + +2. **Breakpoint Strategy** + - Use standard breakpoints unless project specifically requires custom + - Avoid too many breakpoints (complexity vs. benefit) + - Consider content-based breakpoints over device-based + - Use container queries for component-specific responsive needs + +3. **Performance Considerations** + - Minimize layout shifts between breakpoints + - Use `aspect-ratio` utilities to maintain proportions + - Optimize images for different viewport sizes + - Consider critical CSS for above-the-fold content + +4. **Testing and Validation** + - Test across multiple device sizes and orientations + - Verify touch targets are at least 44px on mobile + - Ensure content remains readable at all sizes + - Validate responsive behavior in slow network conditions + +Remember: **Mobile-first responsive design creates better user
