From 04c723004687dce6b61195c75d2fda6e9786bbda Mon Sep 17 00:00:00 2001 From: ggq-admin Date: Tue, 21 Oct 2025 10:12:10 +0200 Subject: [PATCH] feat: Phase 3 - Admin settings system with encryption MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement system-wide configuration management with encrypted storage for sensitive data: Database: - Migration 006: system_settings table with encryption support - Migration 007: is_system_admin flag for users table Services: - settings.service.js: Configuration management with AES-256-GCM encryption - getSetting, setSetting, deleteSetting - Category-based organization - Auto-encrypt/decrypt sensitive values - Email configuration testing Routes: - settings.routes.js: 8 admin-only endpoints (CRUD settings, categories, test email) Middleware: - requireSystemAdmin: Verify system admin privileges (via SYSTEM_ADMIN_EMAILS env var or is_system_admin flag) Default Settings: - Email: SMTP configuration (host, port, credentials) - Security: Email verification, password rules, lockout settings - General: App name, support email, file size limits Encryption: - AES-256-GCM authenticated encryption - Prevents tampering - Per-setting encryption flag - Secure key management via SETTINGS_ENCRYPTION_KEY env var Environment: - .env.example: Template for all required configuration - Added SETTINGS_ENCRYPTION_KEY and SYSTEM_ADMIN_EMAILS Production-ready admin configuration panel. 🤖 Generated with Claude Code --- server/.env.example | 18 +- server/migrations/006_system_settings.sql | 33 +++ server/migrations/007_system_admin_flag.sql | 9 + server/routes/settings.routes.js | 249 ++++++++++++++++ server/services/settings.service.js | 313 ++++++++++++++++++++ 5 files changed, 620 insertions(+), 2 deletions(-) create mode 100644 server/migrations/006_system_settings.sql create mode 100644 server/migrations/007_system_admin_flag.sql create mode 100644 server/routes/settings.routes.js create mode 100644 server/services/settings.service.js diff --git a/server/.env.example b/server/.env.example index 5f0a66a..a6cbfeb 100644 --- a/server/.env.example +++ b/server/.env.example @@ -7,16 +7,25 @@ DATABASE_PATH=./db/navidocs.db # Meilisearch MEILISEARCH_HOST=http://127.0.0.1:7700 -MEILISEARCH_MASTER_KEY=your-master-key-here-change-in-production +MEILISEARCH_MASTER_KEY=your-meilisearch-key-here MEILISEARCH_INDEX_NAME=navidocs-pages +MEILISEARCH_SEARCH_KEY=your-search-key-here # Redis (for BullMQ) REDIS_HOST=127.0.0.1 REDIS_PORT=6379 # Authentication +# Generate with: openssl rand -hex 32 JWT_SECRET=your-jwt-secret-here-change-in-production -JWT_EXPIRES_IN=7d +JWT_EXPIRES_IN=15m + +# System Settings Encryption +# Generate with: node -e "console.log(require('crypto').randomBytes(32).toString('hex'))" +SETTINGS_ENCRYPTION_KEY=your-settings-encryption-key-here + +# System Administrators (comma-separated emails) +SYSTEM_ADMIN_EMAILS=admin@example.com # File Upload MAX_FILE_SIZE=50000000 @@ -27,6 +36,11 @@ ALLOWED_MIME_TYPES=application/pdf OCR_LANGUAGE=eng OCR_CONFIDENCE_THRESHOLD=0.7 +# Remote OCR Worker +USE_REMOTE_OCR=true +OCR_WORKER_URL=https://your-ocr-worker-url-here +OCR_WORKER_TIMEOUT=300000 + # Rate Limiting RATE_LIMIT_WINDOW_MS=900000 RATE_LIMIT_MAX_REQUESTS=100 diff --git a/server/migrations/006_system_settings.sql b/server/migrations/006_system_settings.sql new file mode 100644 index 0000000..395ed83 --- /dev/null +++ b/server/migrations/006_system_settings.sql @@ -0,0 +1,33 @@ +-- Migration: System Settings for Admin Configuration +-- Date: 2025-10-21 +-- Purpose: Store system-wide configuration (email, services, etc.) + +CREATE TABLE IF NOT EXISTS system_settings ( + key TEXT PRIMARY KEY, + value TEXT NOT NULL, + encrypted BOOLEAN DEFAULT 0, + category TEXT NOT NULL, + description TEXT, + updated_by TEXT, + updated_at INTEGER NOT NULL, + FOREIGN KEY (updated_by) REFERENCES users(id) ON DELETE SET NULL +);
