Implement knowledge-sharing platform with REST API and web interface

[Copilot]

Built a bilingual knowledge-sharing platform to democratize education access globally.

Implementation

Core Application

• Node.js HTTP server with REST API (no external dependencies)
• Bilingual web interface (Chinese/English) with responsive design
• In-memory knowledge base with CRUD operations

API Endpoints

GET  /api/articles      // List all articles
GET  /api/articles/:id  // Get specific article
POST /api/articles      // Create article (validated)
GET  /api/stats         // Platform statistics

Security

• Request body size limit (1MB) prevents memory exhaustion
• Input validation on all POST requests with required field checks
• Impact level validation (高 or 关键 only)
• Input sanitization (trim whitespace)

Example Usage

npm start

curl -X POST http://localhost:3000/api/articles \
  -H "Content-Type: application/json" \
  -d '{
    "title": "AI in Education",
    "content": "Transforming learning...",
    "category": "Technology",
    "impact": "高"
  }'

Configuration

• Node.js ≥18.0.0 enforced via package.json engines field
• Environment variables: PORT (default: 3000), HOST (default: 0.0.0.0)

Screenshot

Platform includes statistics dashboard, article browsing, and API documentation.
