Use this context to create components that integrate with these APIs: ${documentationContext} **Integration Requirements:** - Create components that work with the analyzed APIs - Include proper TypeScript interfaces based on API responses - Add error handling for API calls - Include loading states and proper UX - Use the API endpoints and patterns identified in the documentation - Follow the authentication methods described in the docs CRITICAL REQUIREMENTS: 1. Respond with ONLY the React component code - no explanations, no markdown, no text before or after 2. Use function declarations: function ComponentName() { } 3. Use Origin UI design patterns and Tailwind CSS classes with the Origin UI color palette 4. Component must be complete and functional with proper interactivity (useState, onClick handlers, etc.) 5. No import statements needed (React is available globally) 6. Always end your response with: window.default = ComponentName; 7. **INCLUDE MOCK/DEMO API INTEGRATION** - Since this runs in a sandboxed preview: - Use mock data for demonstration purposes - Create realistic demo functionality that doesn't rely on external APIs - Show loading states, error handling, and success states using mock scenarios - Add comments indicating where real API calls would go - Use setTimeout() to simulate API delays and responses 8. Add proper error handling, loading states, and realistic data structures 9. **ADD COMMENTS** in your code indicating API integration points and mock data usage 10. **NO EXTERNAL ASSETS** - Do not reference external fonts, images, or stylesheets. Use only Tailwind classes and system fonts 11. Use realistic API endpoints and data structures FROM THE DOCUMENTATION PROVIDED 12. Include form validation and user feedback 13. **CREATE DEMO FUNCTIONALITY** - Use mock data and simulated API calls for preview functionality 14. **NO TYPESCRIPT SYNTAX** - Use plain JavaScript, avoid type annotations like interface or type definitions 15. Use catch (error) not catch (e: any) for error handling 16. **MOCK DATA APPROACH** - Instead of real API calls, use: - Mock data arrays/objects that represent API responses - setTimeout() to simulate loading states - Conditional logic to show success/error states - Demo buttons that cycle through different states ORIGIN UI DESIGN PATTERNS TO USE: - Colors: Use bg-background, text-foreground, bg-card, text-card-foreground, bg-primary, text-primary-foreground - Borders: Use border-border, rounded-lg (0.625rem radius) - Shadows: Use shadow-sm, shadow-md, shadow-lg - Spacing: Use consistent padding (p-4, p-6, p-8) and gaps (gap-4, gap-6) - Interactive states: Use hover:bg-accent, hover:text-accent-foreground, focus:ring-2 focus:ring-ring - Typography: Use font-medium, font-semibold for headings, text-sm, text-base for body - Buttons: Use bg-primary text-primary-foreground hover:bg-primary/90 rounded-md px-4 py-2 - Cards: Use bg-card text-card-foreground border border-border rounded-lg p-6 shadow-sm EXAMPLE PATTERNS: - Primary Button: className="bg-primary text-primary-foreground hover:bg-primary/90 px-4 py-2 rounded-md font-medium transition-colors" - Card: className="bg-card text-card-foreground border border-border rounded-lg p-6 shadow-sm" - Input: className="bg-background border border-input px-3 py-2 rounded-md focus:ring-2 focus:ring-ring" - Badge: className="bg-secondary text-secondary-foreground px-2 py-1 rounded-md text-sm font-medium" **MOCK DATA EXAMPLE:** Instead of: fetch('/api/plans') Use: \`\`\`javascript const [plans, setPlans] = useState([]); const [loading, setLoading] = useState(false); const fetchPlans = async () => { setLoading(true); // Simulate API call with mock data setTimeout(() => { setPlans([ { id: 1, name: 'Basic', price: 9.99, features: ['Feature 1', 'Feature 2'] }, { id: 2, name: 'Pro', price: 19.99, features: ['All Basic', 'Feature 3', 'Feature 4'] } ]); setLoading(false); }, 1000); }; \`\`\` COMPONENT EXAMPLES: For pricing cards, buttons, modals, forms - create modern, clean designs with: - Proper hover effects and transitions - Interactive functionality (state management) - Responsive design (use flex, grid, responsive prefixes) - Accessibility features (proper ARIA labels, semantic HTML) - Beautiful spacing and typography - Origin UI color scheme and styling patterns - **MOCK API Integration** - Use mock data and simulated delays, not real fetch() calls Remember: Only return the component code with window.default export, nothing else!` : `You are a React component generator specialized in creating beautiful components using Origin UI design patterns and Tailwind CSS.

Browse & Summarize: Read API docs from URLs and extract key information 2. Component Generation: Create typed React components from documentation 3. Integration Instructions: Provide step-by-step implementation guides 4. Multi-API Support: Handle multiple documentation sources (e.g., billing + payments) ## 📋 Step-by-Step Implementation Plan ### Step 1: Add URL Detection to Chat Input What to build: Detect URLs in user messages and show preview Files to modify: - `components/chat/ChatInput.tsx` - Add URL detection - `components/chat/URLPreview.tsx` - New component for URL preview Implementation approach: \`\`\`typescript // Add to ChatInput component const detectUrls = (text: string) => { const urlRegex = /(https?:\/\/[^\s]+)/g; return text.match(urlRegex) || []; }; // Show detected URLs in real-time {detectedUrls.length > 0 && <URLPreview urls={detectedUrls} />} \`\`\` Reference docs: - URL regex patterns: MDN Web Docs - Regular Expressions - React state management: React official docs - useState ### Step 2: Set Up Firecrawl Integration What to build: API route for scraping documentation Files to create: - `app/api/scrape/route.ts` - Scraping API endpoint - `lib/scraping.ts` - Firecrawl wrapper functions Installation: \`\`\`bash npm install @mendable/firecrawl-js \`\`\` Environment variables: \`\`\`bash FIRECRAWL_API_KEY=your_firecrawl_api_key \`\`\` Implementation approach: \`\`\`typescript // Basic Firecrawl setup import FirecrawlApp from '@mendable/firecrawl-js'; const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY }); // Scrape single page for documentation const result = await firecrawl.scrapeUrl(url, { formats: ['markdown'], onlyMainContent: true }); \`\`\` Reference docs: - Firecrawl documentation: https://docs.firecrawl.dev/ - Next.js API routes: https://nextjs.org/docs/app/building-your-application/routing/route-handlers ### Step 3: Add Puppeteer Fallback (Optional) What to build: Fallback scraper for sites that block Firecrawl Files to modify: - `lib/scraping.ts` - Add Puppeteer fallback logic Installation: \`\`\`bash npm install puppeteer npm install --save-dev @types/puppeteer \`\`\` Implementation approach: \`\`\`typescript // Puppeteer fallback for protected sites import puppeteer from 'puppeteer'; const browser = await puppeteer.launch({ headless: true, args: ['--no-sandbox'] }); // Extract main content and convert to markdown const content = await page.evaluate(() => { // Remove scripts, styles, nav, footer // Extract main documentation content return document.querySelector('main, .documentation, #docs')?.textContent; }); \`\`\` Reference docs: - Puppeteer documentation: https://pptr.dev/ - Vercel Puppeteer deployment: https://vercel.com/guides/puppeteer-browserless Note: For Vercel deployment, consider using Browserless.io service instead of local Puppeteer. ### Step 4: Create Documentation Analysis Tool What to build: AI tool that analyzes scraped documentation Files to create: - `lib/tools/browseTool.ts` - AI tool for documentation browsing - `lib/analysis.ts` - Documentation analysis utilities Implementation approach: \`\`\`typescript // AI tool using AI SDK v5 import { tool } from 'ai'; export const browseTool = tool({ description: 'Browse and analyze API documentation', parameters: z.object({ urls: z.array(z.string()), focus: z.string().optional() }), execute: async ({ urls, focus }) => { const results = []; for (const url of urls) { // 1. Scrape documentation const scrapedContent = await scrapeUrl(url); // 2. Analyze with Gemini const analysis = await analyzeDocumentation(scrapedContent, focus); results.push({ url, content: scrapedContent, analysis }); } return { documentationResults: results }; } }); \`\`\` Reference docs: - AI SDK tools documentation: https://sdk.vercel.ai/docs/ai-sdk-core/tools-and-tool-calling - Google Gemini AI: https://ai.google.dev/docs ### Step 5: Enhance Component Generation Tool What to build: Upgrade existing generation to use documentation context Files to modify: - `lib/tools/generateTool.ts` - Add documentation context - `app/api/chat/route.ts` - Include both tools Implementation approach: \`\`\`typescript export const generateTool = tool({ description: 'Generate React components from API documentation', parameters: z.object({ componentName: z.string(), documentationContext: z.string(), // New parameter requirements: z.string(), apiEndpoints: z.array(z.any()).optional() // New parameter }), execute: async ({ componentName, documentationContext, requirements, apiEndpoints }) => { // Enhanced generation prompt with API context const enhancedPrompt = ` Generate ${componentName} component using this API documentation: API DOCUMENTATION: ${documentationContext} KEY ENDPOINTS: ${JSON.stringify(apiEndpoints, null, 2)} REQUIREMENTS: ${requirements} Include: - TypeScript interfaces based on API responses - Error handling for API calls - Loading states - Origin UI styling - Usage examples with real API integration `; return { enhancedPrompt }; } }); \`\`\` ### Step 6: Update Chat API Route What to build: Integrate both tools into chat flow Files to modify: - `app/api/chat/route.ts` - Add both tools to streamText Implementation approach: \`\`\`typescript import { browseTool } from '@/lib/tools/browseTool'; import { generateTool } from '@/lib/tools/generateTool'; export async function POST(req: Request) { const { messages } = await req.json(); const result = await streamText({ model: google('gemini-2.5-pro'), messages, tools: { browse_documentation: browseTool, // New tool generate_component: generateTool // Enhanced tool }, maxSteps: 3, // Allow multi-step execution temperature: 0.1, system: `You are an expert React developer. When users provide URLs, use the browse_documentation tool first to analyze the APIs, then use generate_component tool to create integrated components.` }); return result.toDataStreamResponse(); } \`\`\` ### Step 7: Add Documentation Summary Display What to build: Show documentation analysis in chat Files to create: - `components/chat/DocumentationSummary.tsx` - Display scraped docs summary Implementation approach: \`\`\`typescript // Component to show documentation analysis results export function DocumentationSummary({ results }) { return ( <Card className="mb-4"> <CardHeader> <CardTitle>📚 Documentation Analysis</CardTitle> </CardHeader> <CardContent> {results.map((result, idx) => ( <div key={idx} className="mb-4"> <h4 className="font-medium">{new URL(result.url).hostname}</h4> <p className="text-sm text-gray-600">{result.analysis?.summary}</p> <div className="flex gap-2 mt-2"> {result.analysis?.endpoints?.map((endpoint, i) => ( <Badge key={i} variant="outline">{endpoint}</Badge> ))} </div> </div> ))} </CardContent> </Card> ); } \`\`\` ### Step 8: Enhance Instructions Tab What to build: Better implementation guides with API setup Files to modify: - `components/preview/InstructionsTab.tsx` - Add API setup instructions Implementation approach: \`\`\`typescript // Enhanced instructions with API-specific setup const generateAPIInstructions = (documentationResults) => { return ` ## API Setup ${documentationResults.map(result => ` ### ${result.domain} 1. Sign up at ${result.url} 2. Get API key from dashboard 3. Add to environment: \`${result.envVarName}=your_api_key\` `).join('\n')} ## Component Usage \`\`\`tsx <${componentName} apiKey={process.env.${envVarName}} onSuccess={(data) => console.log(data)} onError={(error) => console.error(error)} /> \`\`\` ## Error Handling - Handle authentication errors (401) - Implement retry logic for rate limits (429) - Validate required props before API calls `; }; \`\`\` ### Step 9: Test Multi-API Integration What to test: The billingsdk.com + dodopayments.com example Test flow: 1. User inputs: "Browse https://billingsdk.com/docs and https://dodopayments.com/docs and create a unified pricing component" 2. System should: - Detect 2 URLs - Scrape both documentation sites - Analyze API structures - Generate component integrating both APIs - Provide setup instructions for both services Testing approach: \`\`\`typescript // Test message for development const testMessage = ` Browse https://stripe.com/docs/api and https://docs.developers.paypal.com and create a unified payment component with pricing tiers `; // Expected AI workflow: // 1. browseTool extracts both API documentation // 2. generateTool creates component using both APIs // 3. Result shows unified component with both integrations \`\`\` ### Step 10: Production Deployment Considerations What to prepare: 1. Environment Variables: \`\`\`bash FIRECRAWL_API_KEY=your_key PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium # For Vercel \`\`\` 2. Vercel Configuration: \`\`\`json // vercel.json { "functions": { "app/api/scrape/route.ts": { "maxDuration": 30 }, "app/api/chat/route.ts": { "maxDuration": 30 } } } \`\`\` 3. Error Handling: - Timeout handling for slow documentation sites - Graceful fallback when scraping fails - User-friendly error messages Reference docs: - Vercel deployment: https://vercel.com/docs/deployments - Environment variables: https://nextjs.org/docs/app/building-your-application/configuring/environment-variables ## 🎯 Expected Final Outcome User Experience: \`\`\` User: "Browse https://stripe.com/docs and create payment form component" System Response: 1. 🌐 "Browsing Stripe documentation..." 2. 📊 "Found API endpoints: /charges, /customers, /payment-methods..." 3. ⚡ "Generating payment component with Stripe integration..." 4. 📋 "Component generated with setup instructions" Result: - TypeScript component with Stripe API integration - Props based on Stripe API requirements - Step-by-step setup guide - Error handling for Stripe-specific errors \`\`\` Success Criteria: ✅ Detects URLs in user messages ✅ Successfully scrapes documentation content ✅ Generates components with API-specific props ✅ Provides implementation instructions ✅ Handles multiple APIs in single request ✅ Works with billing + payment example scenario This step-by-step approach will extend your existing Prism app with smart documentation analysis while keeping the implementation clean and minimal.
