Front-End Integration

Rationale

Efficient front-end integration improves performance, maintainability, and user experience. It enables scalable development and easier collaboration between teams.

Asset Management

Organize and manage CSS, JavaScript, and image assets in public/ or assets/ directories. Use hashed filenames for cache busting and bundle assets for production.

Example:

// Good: Import and bundle assets
import './styles/main.css';
import logo from './assets/logo.png';

// Bad: Inline styles and unorganized assets
const style = '<style>body { color: red; }</style>';
document.head.innerHTML += style;
  • Use tools like Webpack, Vite, or Parcel for asset bundling and optimization.
  • Use hashed filenames for cache busting: main.abc123.css
  • Organize assets by type: assets/images/, assets/css/, assets/js/

Framework Integration

Integrate front-end frameworks (e.g., React, Vue) using build tools or via APIs. Serve built assets from the public directory.

Example (React):

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
ReactDOM.createRoot(document.getElementById('root')).render(<App />);

Example (Vue):

import { createApp } from 'vue';
import App from './App.vue';
createApp(App).mount('#app');
  • Register components in entry files (e.g., index.js, main.js).
  • Use environment variables for API endpoints and config.

Accessibility & Responsive Design

  • Use semantic HTML and ARIA attributes for accessibility.
  • Ensure keyboard navigation and screen reader compatibility.
  • Use media queries and flexible layouts for responsive design. Example:
    // Good: Accessible button
    <button aria-label="Close" onClick={handleClose}>×</button>

Performance Optimization

  • Minimize and bundle assets for production.
  • Use CDN for serving static files in production.
  • Lazy load images and components where possible.
  • Test front-end builds and integration as part of CI/CD.

Best Practices

  • Minimize and bundle assets for production.
  • Use CDN for serving static files in production.
  • Document asset structure and build steps for new team members.
  • Write tests for critical front-end functionality.
  • Use automated tools (Lighthouse, axe) for accessibility and performance checks.
  • Involve real users in usability testing when possible.
