# JWT Architecture Consolidation - v5.2.0 **Document**: Centralized JWT Configuration Architecture **Version**: v5.2.0 FULLY OPERATIONAL **Date**: January 12, 2025 **Status**: 🔧 ARCHITECTURE IMPROVEMENT - JWT Consolidation **Sync**: EuConquisto Composer MCP v5.2.0 ## Problem Analysis ### Before: Fragmented JWT References (Poor Practice) The system had **6+ different hardcoded paths** for the same JWT token file: ```javascript // Pattern 1: Archive path const tokenPath = join(PROJECT_ROOT, 'archive/authentication/correct-jwt-new.txt'); // Pattern 2: Project root const tokenPath = join(PROJECT_ROOT, 'correct-jwt-new.txt'); // Pattern 3: Server directory this.jwtFilePath = path.join(__dirname, 'correct-jwt-new.txt'); // Pattern 4: Relative paths const tokenPath = resolve(currentDir, '..', 'correct-jwt-new.txt'); // Pattern 5: Hardcoded absolute paths const jwtToken = fs.readFileSync('/Users/.../correct-jwt-new.txt', 'utf8'); // Pattern 6: Various __dirname combinations const jwtPath = join(__dirname, 'archive/authentication/correct-jwt-new.txt'); ``` ### Issues Identified 1. **Maintenance Nightmare**: Changes require updating 20+ files 2. **Fragility**: Moving/renaming token file breaks multiple components 3. **Inconsistency**: Different files look in different locations 4. **No Single Source of Truth**: No centralized configuration 5. **Error Prone**: Easy to miss references during updates 6. **Poor Debugging**: Hard to track down JWT loading issues ## Solution: Centralized JWT Configuration ### After: Single Source of Truth (Best Practice) ```javascript // All files now use: import { getJWTToken, getJWTPrimaryPath } from '../src/config/jwt-config.js'; // Simple token loading const token = getJWTToken(); // Path access if needed const tokenPath = getJWTPrimaryPath(); ``` ### Architecture Components #### 1. Centralized Configuration Module **File**: `/src/config/jwt-config.js` ```javascript export class JWTConfig { constructor() { this.primaryPath = join(PROJECT_ROOT, 'config', 'jwt-token.txt'); this.fallbackPaths = [ join(PROJECT_ROOT, 'archive', 'authentication', 'correct-jwt-new.txt'), join(PROJECT_ROOT, 'correct-jwt-new.txt'), join(PROJECT_ROOT, 'tools', 'servers', 'correct-jwt-new.txt') ]; } loadToken() { // Intelligent loading with fallbacks } } ``` #### 2. Standardized Location **Primary Path**: `/config/jwt-token.txt` - Clean, semantic naming - Dedicated configuration directory - Clear separation from source code #### 3. Intelligent Fallback System - Automatic fallback to legacy locations - Graceful migration path - Clear logging for debugging ## Migration Strategy ### Phase 1: Infrastructure (Complete ✅) - ✅ Created centralized JWT configuration module - ✅ Established primary JWT location (`/config/jwt-token.txt`) - ✅ Implemented intelligent fallback system - ✅ Created migration tooling ### Phase 2: Critical Files Migration (In Progress 🔧) **Target Files**: - `dist/browser-automation-api-jit-v5.1.0.js` (Main production entry) - `tools/servers/jwt-redirect-server-v1.0.2.js` (JWT server) **Migration Tool**: `/utils/migrate-jwt-references.js` ### Phase 3: Gradual Migration (Future) - Update remaining source files progressively - Remove duplicate token files - Clean up legacy path references ## Implementation Details ### New Usage Pattern ```javascript // Before (Fragmented) try { const tokenPath = join(PROJECT_ROOT, 'archive/authentication/correct-jwt-new.txt'); this.jwtToken = readFileSync(tokenPath, 'utf-8').trim(); } catch (error) { try { const fallbackPath = join(PROJECT_ROOT, 'correct-jwt-new.txt'); this.jwtToken = readFileSync(fallbackPath, 'utf-8').trim(); } catch (fallbackError) { // Handle error } } // After (Centralized) import { getJWTToken } from '../src/config/jwt-config.js'; this.jwtToken = getJWTToken(); // Handles all fallbacks automatically ``` ### Error Handling ```javascript // Centralized error handling with clear messaging try { const token = getJWTToken(); } catch (error) { console.error(` ❌ JWT Token not found in any configured location: Primary: /config/jwt-token.txt Fallbacks: /archive/authentication/correct-jwt-new.txt, ... Please ensure the JWT token file exists in one of these locations. `); } ``` ### Configuration Access ```javascript import { jwtConfig, getJWTToken, getJWTPrimaryPath } from '../src/config/jwt-config.js'; // Simple token access const token = getJWTToken(); // Path information const primaryPath = getJWTPrimaryPath(); const fallbacks = jwtConfig.getFallbackPaths(); // Force reload (if token changes) jwtConfig.resetToken(); ``` ## Benefits ### 1. Maintainability ✅ - **Single point of change** for JWT configuration - **Easy token file relocation** without breaking system - **Centralized fallback logic** instead of scattered implementations ### 2. Reliability ✅ - **Consistent token loading** across all components - **Automatic fallback system** prevents failures - **Better error messages** for debugging ### 3. Security ✅ - **Clear token file location** management - **Consistent access patterns** reduce security mistakes - **Centralized validation** and error handling ### 4. Developer Experience ✅ - **Simple API** (`getJWTToken()` vs complex path logic) - **Clear documentation** of JWT architecture - **Migration tooling** for safe updates ## File Structure ### Current JWT Locations ``` /config/ ├── jwt-token.txt # ✅ PRIMARY - New centralized location /archive/authentication/ ├── correct-jwt-new.txt # 🔄 FALLBACK - Legacy location /tools/servers/ ├── correct-jwt-new.txt # 🔄 FALLBACK - Server location /correct-jwt-new.txt # 🔄 FALLBACK - Root location ``` ### Recommended Cleanup (Post-Migration) ``` /config/ ├── jwt-token.txt # ✅ ONLY LOCATION # Remove duplicates after migration complete ``` ## Migration Commands ### Run Migration Tool ```bash cd /path/to/project node utils/migrate-jwt-references.js ``` ### Manual Migration Pattern ```javascript // Replace this pattern: const tokenPath = join(PROJECT_ROOT, 'any/path/to/correct-jwt-new.txt'); const token = readFileSync(tokenPath, 'utf-8').trim(); // With this pattern: import { getJWTToken } from '../src/config/jwt-config.js'; const token = getJWTToken(); ``` ## Testing ### Verify Centralized Loading ```javascript import { getJWTToken } from './src/config/jwt-config.js'; try { const token = getJWTToken(); console.log('✅ JWT loaded successfully:', token.length, 'characters'); } catch (error) { console.error('❌ JWT loading failed:', error.message); } ``` ### Test Fallback System ```bash # Move primary token temporarily mv config/jwt-token.txt config/jwt-token.txt.backup # Verify fallback works node -e "import('./src/config/jwt-config.js').then(m => console.log('Token length:', m.getJWTToken().length))" # Restore primary token mv config/jwt-token.txt.backup config/jwt-token.txt ``` ## Success Criteria ### ✅ Phase 1 Complete - [x] Centralized JWT configuration module created - [x] Primary JWT location established - [x] Intelligent fallback system implemented - [x] Migration tooling created ### 🔧 Phase 2 In Progress - [ ] Critical production files migrated - [ ] JWT redirect server updated - [ ] Production testing completed ### ⏳ Phase 3 Future - [ ] All source files migrated - [ ] Legacy token files removed - [ ] Documentation updated ## Conclusion This JWT architecture consolidation transforms a fragmented, error-prone system into a maintainable, reliable configuration architecture. The centralized approach eliminates the **6+ different hardcoded paths** problem and provides a foundation for robust JWT token management. **Impact**: - **Before**: 20+ files with hardcoded JWT paths - **After**: Single import statement: `getJWTToken()` This change significantly improves system integrity and maintenance efficiency.
