Frontend-Backend Integration Fixes

Issues Identified and Fixed

1. Environment Variables Inconsistency

Problem: Frontend was using inconsistent environment variable names (NEXT_API_PUBLIC_URL vs NEXT_PUBLIC_API_URL) Solution:

  • Updated .env file to use consistent naming
  • Updated API routes to use NEXT_PUBLIC_SERVER_URL and NEXT_PUBLIC_API_URL

2. Duplicate Authentication Providers

Problem: Two different AuthProvider implementations causing conflicts Solution:

  • Consolidated to a single AuthProvider in components/providers/auth-provider.tsx
  • Removed duplicate hooks/use-auth.tsx (renamed to backup)
  • Added proper TypeScript interfaces and error handling

3. Inconsistent API Calling Patterns

Problem: Mixed usage of direct backend calls and Next.js API routes in use-user-api.ts Solution:

  • Updated all API calls to use consistent Next.js API route pattern (/api/...)
  • Removed the generic makeRequest function
  • Added proper error handling and token management for all endpoints

4. Missing/Inconsistent Authorization Headers

Problem: Some API calls weren't properly sending authorization headers Solution:

  • Standardized authorization header format: Authorization: Bearer ${token}
  • Added proper token validation in all API routes
  • Consistent error responses for unauthorized requests

5. API Route Error Handling

Problem: Inconsistent error handling across API routes Solution:

  • Standardized error response format
  • Added proper HTTP status codes
  • Improved error messages and logging

Updated Files

Frontend

  1. .env - Fixed environment variable names
  2. hooks/use-user-api.ts - Complete rewrite for consistency
  3. components/providers/auth-provider.tsx - Consolidated auth provider
  4. app/api/user/verify-token/route.ts - Fixed environment variable usage
  5. app/api/user/profile/[userId]/route.ts - Added profile management routes
  6. app/api/user/profile/[userId]/complete/route.ts - Fixed error handling
  7. app/api/user/profile/[userId]/projects/route.ts - Fixed error handling
  8. app/api/upload/single/route.ts - Created upload route
  9. app/api/upload/multiple/route.ts - Created multiple upload route
  10. app/api/upload/[filename]/route.ts - Created delete file route

Configuration

  • Environment Variables: Consistent naming between frontend and backend
  • CORS: Backend already configured to accept frontend requests
  • Rate Limiting: Backend has proper rate limiting for different endpoint types

Integration Pattern

The application now follows this pattern:

Frontend Component → useUserAPI Hook → Next.js API Route → Backend Express Server

Authentication Flow

  1. User logs in through /api/user/login
  2. JWT token stored in localStorage
  3. All subsequent API calls include Authorization: Bearer ${token} header
  4. Next.js API routes forward requests to backend with proper authentication
  5. Backend validates JWT and processes requests

API Route Structure

├── login (POST)
├── verify-token (GET)
├── complete-profile (POST)
├── profile/[userId]/
│   ├── route.ts (GET, PUT)
│   ├── complete/ (GET)
│   ├── projects/ (GET, POST)
│   ├── experiences/ (GET, POST)
│   ├── achievements/ (GET, POST)
│   ├── certifications/ (GET, POST)
│   └── profile-links/ (GET, POST)
├── projects/[projectId]/ (PUT, DELETE)
├── experiences/[experienceId]/ (PUT, DELETE)
├── achievements/[achievementId]/ (PUT, DELETE)
├── certifications/[certificationId]/ (PUT, DELETE)
└── profile-links/[profileLinkId]/ (PUT, DELETE)

/api/upload/

Testing Status

✅ Frontend Development Server: Running on http://localhost:3000 ⏳ Backend Server: Needs to be started on http://localhost:5000 ⏳ Database: MongoDB connection needs verification

Next Steps for Complete Integration

  1. Start Backend Server:

    cd server
npm start

  2. Verify Database Connection:

    • Check MongoDB is running (local or Atlas)
    • Verify connection string in server/.env

  3. Test API Endpoints:

    • Login functionality
    • Profile management
    • File upload
    • CRUD operations for projects, experiences, etc.

  4. Production Deployment:

    • Update environment variables for production URLs
    • Configure CORS for production domains
    • Set up proper SSL certificates

Key Improvements Made

  • Type Safety: Proper TypeScript interfaces throughout
  • Error Handling: Comprehensive error handling with meaningful messages
  • Security: Proper JWT token validation and secure headers
  • Consistency: Uniform API patterns and response formats
  • Maintainability: Clean separation of concerns and consistent code style
