Building a Multi-Language Code Integration Component with React & TypeScript 🚀


This content originally appeared on DEV Community and was authored by Alaa

Ever wanted to showcase your API or SDK across multiple programming languages in a beautiful, interactive way? I built a comprehensive SDK integration component that displays implementation examples for 12+ programming languages with framework-specific variations.

🚀 Try the live demo here!

What Makes Great SDK Integration UX? 🎯

When developers visit your documentation or landing page, they want to see code examples that match their tech stack. A great SDK integration component should:

  • Support multiple languages – From Node.js to Rust, Python to .NET
  • Show framework variations – Express vs Next.js vs NestJS for Node.js
  • Provide copy-paste ready code – No placeholder values or incomplete examples
  • Be visually appealing – Clean syntax highlighting and smooth animations
  • Remember user preferences – Persist language and framework selections

The Tech Stack 🛠 

// Core technologies
- React 18 + TypeScript
- Tailwind CSS for styling
- shadcn/ui components  
- Radix UI primitives
- Framer Motion for animations
- Simple Icons for language logos
- Lucide React for UI icons

Key Features:

🌍 12+ Programming Languages

  • Backend: Node.js, Python, PHP, Go, Ruby, Rust, Java, Elixir, .NET
  • Protocols: REST API, SMTP
  • Serverless: Serverless functions support

🎯 Framework-Specific Examples

Each language includes 2-3 popular frameworks:

  • Node.js: Express, Next.js, NestJS
  • Python: Django, Flask, FastAPI
  • PHP: Laravel, Symfony, CodeIgniter
  • Go: Gin, Echo, Fiber
  • Rust: Actix, Axum, Warp
  • And many more…

🎨 Smart Visual States

  • Language Selection: Interactive tabs with language icons
  • Framework Switching: Nested tabs for framework variations
  • Syntax Highlighting: Custom highlighting for keywords and strings
  • Copy Functionality: One-click code copying with visual feedback

Performance Optimizations 🚀

  • Lazy Loading: Code snippets are only rendered when needed
  • Memoization: Framework tabs are memoized to prevent unnecessary re-renders
  • Efficient Animations: Framer Motion with optimized transition settings
  • Local Storage: User preferences persist across sessions

Responsive Design 📱

The component is fully responsive with:

  • Mobile-first approach with horizontal scrolling for language tabs
  • Flexible code blocks that adapt to screen size
  • Touch-friendly interface elements
  • Optimized typography for different screen sizes

Key Features Checklist ✅

  • ✅ 12+ Programming Languages with authentic icons
  • ✅ Framework-Specific Examples (3+ per language)
  • ✅ Copy-to-Clipboard functionality
  • ✅ Syntax Highlighting with custom color scheme
  • ✅ Smooth Animations using Framer Motion
  • ✅ Persistent State with localStorage
  • ✅ Responsive Design for all screen sizes
  • ✅ TypeScript Support with full type safety
  • ✅ Accessibility with proper ARIA labels
  • ✅ Theme Support for light/dark modes

What I Learned 🎓

Building this component taught me several valuable lessons:

  1. State Management Complexity: Managing nested state (language → framework) requires careful consideration of validation and persistence
  2. Icon Integration: Using Simple Icons for consistent, high-quality language logos
  3. Animation Performance: Balancing smooth animations with performance using Framer Motion’s optimized settings
  4. Code Organization: Structuring large code snippet objects in a maintainable way
  5. User Experience: The importance of remembering user preferences and providing immediate visual feedback

The Result 🎉

The final SDK integration component provides a comprehensive, interactive way to showcase API integrations across multiple programming languages. It’s perfect for:

  • API Documentation – Show SDK implementation examples
  • Landing Pages – Demonstrate multi-language SDK support
  • Developer Portals – Help developers get started quickly with your SDK
  • Open Source Projects – Showcase community SDK support
