Frontend Guideline Document: Xmind AI Desktop Client Landing Page

1. Introduction

Objective: Develop a responsive, high-performance landing page for "Xmind使用入口地址 Ai桌面客户端最新工具和软件app下载" to drive downloads of the Xmind AI Desktop Client. The page must showcase Xmind’s core features (unlimited nodes, multi-diagram support, cross-platform compatibility) while prioritizing user conversion.

Key Requirements:

• Cross-browser compatibility (Chrome, Firefox, Safari, Edge)
• Mobile-first responsive design (≥95 Lighthouse score)
• Secure download handling with integrity checks
• Localized content (Chinese primary, English optional)

2. Technology Stack

3. Implementation Steps

3.1 Project Initialization

npm create vite@latest xmind-landing --template react-ts
npm install -D tailwindcss postcss autoprefixer sass
npx tailwindcss init -p

3.2 Core Component Structure

src/
├── components/
│   ├── HeroSection.tsx       // Main CTA with download buttons
│   ├── FeatureGrid.tsx       // Showcases Xmind features (icons + text)
│   ├── DownloadCard.tsx      // OS-specific download cards (Windows/macOS/Linux)
│   └── Testimonials.tsx      // User reviews (carousel)
├── hooks/
│   └── useDownloadTracker.ts // Tracks download clicks (Zustand)
├── assets/                   // SVGs, optimized images (WebP format)
└── App.tsx                   // Root component with routes

3.3 Responsive Workflow

• Breakpoints: sm:640px, md:768px, lg:1024px (Tailwind defaults)
• Flexbox/Grid for feature card alignment.
• Dynamic download button visibility: Show OS-specific buttons via navigator.userAgent detection.

3.4 Performance Optimization

• Lazy-load testimonials and non-critical images (<img loading="lazy" />).
• Code splitting with React.lazy() for route-based chunks.
• Preconnect to CDNs for fonts (Google Fonts) and analytics.

3.5 Security

• Download links served over HTTPS with rel="noopener noreferrer".
• Subresource Integrity (SRI) hashes for all third-party scripts.
• CSP headers via vite-plugin-csp (nonce-based).

4. Accessibility & Localization

• WCAG 2.1 AA Compliance:
  • Semantic HTML (<section>, <article>).
  • ARIA labels for interactive elements (e.g., aria-label="Download for Windows").
  • Color contrast ≥ 4.5:1 (verified via axe-core).
• Localization:
  • i18next 23.2 for string management.
  • Language switcher with zh-CN (default) and en-US support.

5. Testing Strategy

6. Deployment & CI/CD

• Hosting: Vercel (static hosting with edge caching).
• CI/CD Pipeline:
  复制

  # .github/workflows/deploy.yml
  steps:
    - run: npm ci
    - run: npm run build
    - run: npm run test
    - uses: vercel/action@v1 # Deploys to Vercel

• Cache Policy:
  • Static assets: Cache-Control: public, max-age=31536000, immutable
  • HTML: max-age=300 (stale-while-revalidate)

7. Scalability & Maintenance

• Theming: Tailwind theme.extend for brand colors (Xmind’s purple/blue palette).
• Analytics Integration: Event tracking for download clicks (e.g., gtag('event', 'download_win')).
• Error Monitoring: Sentry SDK for runtime errors.
• Future-Proofing:
  • Atomic design system for component reuse.
  • Feature flags (via LaunchDarkly) for phased rollouts.
