Add frontend for managing API keys#22
Conversation
- Add ApiKeyManager utility for safe JSON-based API key storage - Add ApiKeyController with CRUD endpoints for API key management - Create Vue 3 Composition API frontend for managing API keys - Add /admin and /keys routes to serve the management interface - Implement file locking to prevent concurrent write issues - Add user-to-API-key association tracking
- Create separate Vue 3 project in frontend/ directory with own package.json - Use Vite as build tool and Vue 3 Composition API with <script setup> - Update Dockerfile to build both frontend and backend projects - Update backend build script to copy frontend build output to dist/static - Remove incorrect package-lock.json (project uses yarn) - Remove CDN-based static HTML file - Frontend builds to frontend/dist, then copied to dist/static during backend build
- Add jest, ts-jest, and @types/jest dependencies - Create jest.config.js for TypeScript support - Add comprehensive tests for ApiKeyManager (15 tests covering CRUD operations) - Update GitHub Actions workflow to run tests on push and PR - Test job runs before build job to ensure code quality - All tests passing successfully
- Update GitHub Actions workflow to run only on PR events (opened, synchronize, reopened) - Add in-memory cache to ApiKeyManager for faster API key lookups - Keys are loaded into memory on initialization and kept in sync with disk - Add apiKeyMiddleware to validate API keys before proxying LLM requests - LLM proxy now validates API keys against stored keys (revocation support) - All API key operations use cache, eliminating repeated disk reads - Tests continue to pass with new caching behavior
Implement comprehensive per-API-key request tracking with: - RequestTracker utility for CSV-based storage (epoch ms timestamps) - Track start/end times per request (null endTime for failures) - In-memory caching of last week's data - Analytics API endpoint with date range query support - Frontend analytics tab with table display and date pickers - Request success/failure status tracking in middleware Analytics features: - Default view shows last week of data - Custom date range picker for historical queries - Table displays: start time (dd/mm/yyyy hh:mm:ss), elapsed (ms), status - Summary statistics: total requests, successful, failed Modified apiKeyMiddleware to intercept response completion and track timing data.

Automated review 🤖 Summary of ChangesThis pull request introduces a comprehensive frontend application for managing API keys within the LLM Proxy system. The changes include adding Vue.js-based UI components for authentication, API key creation/deletion, and analytics viewing. Backend support is enhanced with new controllers for API key management and analytics tracking, along with updated middleware for API key validation and request monitoring. CI workflows are also improved to include testing and better build processes. Key Changes & Positives• Frontend Implementation: 🟢 Added complete Vue.js frontend with login, API key management, and analytics views Potential Issues & Recommendations

However, several security concerns need addressing:
Once these security and quality improvements are addressed, the PR will be ready for production use. The feature implementation itself is well-structured and follows modern patterns. |
Security Enhancements: - Implement HttpOnly cookie-based authentication (XSS protection) - Add comprehensive input validation using Joi library - Configure CORS with credential support - Replace DOM manipulation with proper Vue patterns Validation: - Username: 3-50 chars, alphanumeric only - Password: 8-128 chars - API keys: 64-char hex string format validation - Timestamps: reasonable range validation - All endpoints validate inputs before processing Testing: - Add unit tests for analytics controller - Test coverage for validation logic - Test auth middleware (token and API key) - All tests passing with Jest Infrastructure: - Add .dockerignore for optimized builds - Update dependencies (cookie-parser, cors, joi) - Add cookie-parser middleware - CORS origin configurable via CORS_ORIGIN env var Frontend Updates: - Remove localStorage entirely (security risk) - Use cookies with credentials: 'include' - Simplified clipboard with fallback message - Check authentication on mount via API call Backend Updates: - New /auth/login endpoint (cookie-based) - New /auth/logout endpoint - Legacy /auth/token maintained for API clients - TokenMiddleware supports both cookies and Bearer tokens - All validation errors return descriptive messages Documentation: - Comprehensive README update - Security practices section - Secret management best practices - API endpoint documentation - Development and testing guide - Troubleshooting section

Approval Recommendation Approve with caveats ✅ Should approve after addressing:
The PR significantly enhances the product with valuable administrative capabilities while maintaining good architectural practices. The main concerns are around operational security and some UX details that would benefit from refinement. |
The afterEach cleanup was removing the entire __tests__ directory by calling fs.remove(path.dirname(testFilePath)). This deleted the test file itself after running tests. Removed the problematic line - only clean up the test data files, not the directory containing the test file.

tsconfig.json is required for the TypeScript build to work. Removing it from .dockerignore caused tsc to fail in Docker builds.
