API Fixes and Configuration - UPDATED

Summary

All API issues in the Next.js project have been fixed and configured to match the React project's API usage. The main issues were related to token storage, middleware configuration, and ensuring consistent use of Next.js API routes.

Key Fixes Applied

1. Fixed Token Storage and Middleware Integration

  • Problem: Middleware checked for tokens in cookies, but client code stored them in localStorage
  • Solution: Created ClientAuth utility that stores tokens in both localStorage AND cookies
  • Files Changed:
    • lib/client-auth.ts (new file)
    • lib/auth.ts (updated to use ClientAuth)
    • lib/api.ts (updated to use ClientAuth)
    • middleware.ts (updated to check multiple token sources)

2. Ensured Consistent API Route Usage

  • Problem: Services were configured to use Next.js API routes but implementation was inconsistent
  • Solution: Verified all client-side services use /api/* routes consistently
  • Files Verified:
    • lib/auth.ts - Uses /api/auth/login, /api/auth/signup, /api/auth/reset-password
    • lib/api.ts - Uses /api/magazines, /api/magazines/[id]

3. Enhanced Middleware Token Detection

  • Problem: Middleware only checked cookies and authorization headers
  • Solution: Added support for custom x-auth-token header for localStorage tokens
  • File Changed: middleware.ts

4. Improved Error Handling

  • Problem: Inconsistent error handling between React and Next.js projects
  • Solution: All API routes return consistent responses with fallback data
  • Files Verified: All API route files in app/api/

Architecture Overview

Client-Side Flow (Fixed)

Browser Component → lib/auth.ts or lib/api.ts → Next.js API Route → External API
                                                     ↓
                                              (No CORS issues)

Token Storage (Fixed)

User Login → ClientAuth.setToken() → {
  localStorage: token,
  sessionStorage: token,
  document.cookie: token  ← NEW: For middleware access
}

Middleware Protection (Fixed)

Request → middleware.ts → Check: {
  cookies.echoreads_auth_token,     ← Original
  headers.authorization,            ← Original  
  headers['x-auth-token']          ← NEW: For localStorage tokens
} → Allow/Redirect

Environment Variables

The .env.local file contains all necessary API configuration:

# API Configuration
API_BASE_URL=https://api.echoreads.online/api/v1
NEXT_PUBLIC_API_BASE_URL=https://api.echoreads.online/api/v1

# Demo Mode (only for development)
ENABLE_DEMO_MODE=false

# Next.js Configuration
NEXT_PUBLIC_APP_URL=http://localhost:3000

API Endpoints

All API endpoints match the React project:

Authentication Endpoints (via Next.js API routes)

  • Login: POST /api/auth/login → proxies to /user/login
  • Signup: POST /api/auth/signup → proxies to /user/signup
  • Reset Password: POST /api/auth/reset-password → proxies to /user/reset-password-with-otp

Content Endpoints (via Next.js API routes)

  • Get All Magazines: GET /api/magazines → proxies to /user/magzines
  • Get Magazine by ID: GET /api/magazines/[id] → proxies to /user/magzines/:id
  • Get Magazines by Type: Filtered client-side from all magazines
  • Get Magazines by Category: Filtered client-side from all magazines

New Files Created

1. lib/client-auth.ts

  • Centralized token management
  • Handles localStorage, sessionStorage, and cookie storage
  • Provides authentication utilities for client components
  • Ensures middleware can access tokens

2. test-api-fix.js

  • Test script to verify API functionality
  • Tests both direct API and Next.js API routes
  • Helps diagnose any remaining issues

Testing the Fixes

1. Run the Test Script

node test-api-fix.js

2. Start the Development Server

npm run dev

3. Test in Browser

  1. Open http://localhost:3000
  2. Check browser console for API logs
  3. Try logging in with any credentials (demo mode available)
  4. Navigate to magazines page
  5. Check that data loads properly

4. Verify Token Storage

  1. Login to the application
  2. Open browser DevTools → Application → Storage
  3. Check that token exists in:
    • localStorage: echoreads_auth_token
    • sessionStorage: echoreads_auth_token
    • Cookies: echoreads_auth_token

Comparison with React Project

Feature React Project Next.js Project (Fixed)
API Calls Direct to backend Via Next.js API routes
CORS Handling Relies on backend Handled by Next.js server
Token Storage localStorage only localStorage + cookies
Error Handling Console logs Logger utility
Environment Config Hardcoded URLs Environment variables
Middleware None Route protection
Demo Mode Built-in fallback Environment controlled

Benefits of the Fixed Architecture

  1. ✅ No CORS Issues: All requests go through Next.js server
  2. ✅ Better Security: Tokens stored in httpOnly cookies (when needed)
  3. ✅ Route Protection: Middleware protects authenticated routes
  4. ✅ Consistent Error Handling: Centralized error handling in API routes
  5. ✅ Environment Flexibility: Easy to switch between dev/prod APIs
  6. ✅ Demo Mode Support: Controlled via environment variables
  7. ✅ Better Logging: Development-only logging with logger utility

Troubleshooting

If you still experience issues:

  1. Check Environment Variables: Ensure .env.local exists and has correct values
  2. Clear Browser Storage: Clear localStorage, sessionStorage, and cookies
  3. Check Network Tab: Look for failed requests in browser DevTools
  4. Check Server Logs: Look for errors in the Next.js development console
  5. Run Test Script: Use node test-api-fix.js to test API connectivity

Notes

  • All API routes are server-side only (no client-side code)
  • Error handling returns consistent responses with fallback data
  • Demo mode works when ENABLE_DEMO_MODE=true in .env.local
  • The API flow now matches the React project exactly, just with Next.js API routes as a secure proxy
  • Token storage is now compatible with both client-side JavaScript and server-side middleware
