   • Clicks "Save and Share"
   • System generates a unique URL for the snippet

2. Snippet Discovery and Use:

   • User enters search terms or browses categories
   • Views list of relevant snippets
   • Clicks on a snippet to view details
   • Copies snippet or forks it to their collection
   • Optionally leaves a comment or rating

3. Profile and Settings Management:

   • User navigates to profile page
   • Updates personal information and preferences
   • Manages snippet collections and organization
   • Adjusts notification settings
   • Views activity history and statistics

Technical Specifications

File Structure

Implementation Plan

1. Project Setup (1-2 days)

   • Initialize Git repository
   • Set up React frontend with Create React App
   • Set up Node.js backend with Express
   • Configure ESLint and Prettier

2. Backend Development (5-7 days)

   • Implement user authentication (register, login, JWT)
   • Create database models and migrations
   • Develop RESTful API endpoints for snippets, users, and tags
   • Implement search functionality

3. Frontend Development (7-10 days)

   • Create reusable UI components
   • Implement user authentication flows
   • Develop snippet creation, editing, and viewing pages
   • Create user profile and settings pages
   • Implement search and discovery features

4. Integration and Testing (3-5 days)

   • Connect frontend with backend API
   • Implement error handling and loading states
   • Write unit and integration tests
   • Perform manual testing and bug fixes

5. Enhancement and Optimization (3-4 days)

   • Add syntax highlighting for multiple languages
   • Implement snippet forking and version control
   • Optimize performance and loading times
   • Enhance responsive design for mobile devices

6. Deployment and Documentation (2-3 days)

   • Set up production environment
   • Deploy application to chosen cloud provider
   • Write user documentation and API documentation
   • Create README and contribution guidelines

7. Final Testing and Launch (1-2 days)

   • Perform final round of testing
   • Address any last-minute issues
   • Launch the application

Deployment Strategy

1. Set up separate staging and production environments
2. Use Docker to containerize the application for consistent deployment
3. Deploy backend to a scalable cloud platform (e.g., AWS Elastic Beanstalk or Heroku)
4. Use a managed PostgreSQL database service (e.g., AWS RDS or Heroku Postgres)
5. Deploy frontend to a CDN for fast global access (e.g., AWS CloudFront or Netlify)
6. Implement CI/CD pipeline using GitHub Actions or GitLab CI
7. Set up monitoring and logging (e.g., ELK stack or Datadog)
8. Configure automatic backups for the database
9. Implement SSL/TLS encryption for all communications
10. Use environment variables for sensitive configuration data

Design Rationale

• React and Node.js were chosen for their robust ecosystem and developer productivity
• PostgreSQL provides strong data integrity and supports complex queries for efficient snippet management
• JWT authentication ensures secure and stateless user sessions
• Docker containerization simplifies deployment and ensures consistency across environments
• The modular file structure promotes code organization and scalability
• Implementing search functionality early on ensures it's deeply integrated into the platform's architecture
• Syntax highlighting and language support are crucial for a code-centric application
• The phased implementation plan allows for iterative development and early feedback
