+# DMS Architecture Deep Dive (Backend + Frontend)
+
+**Project:** Document Management System (DMS) — LCBP3
+**Platform:** QNAP TS‑473A (Container Station)
+**Last updated:** 2025‑10‑07 (UTC+7)
+
+---
+
+## 0) TL;DR (Executive Summary)
+
+* Reverse proxy (Nginx/NPM) เผยแพร่ Frontend (Next.js) และ Backend (Node.js/Express) ผ่าน HTTPS (HSTS)
+* Backend เชื่อม MariaDB 10.11 (ข้อมูลหลัก DMS) และแยก n8n + Postgres 16 สำหรับ workflow
+* RBAC/ABAC ถูกบังคับใช้งานใน middleware + มีชุด SQL (tables → triggers → procedures → views → seed)
+* ไฟล์จริง (PDF/DWG) เก็บนอก webroot ที่ **/share/dms‑data** พร้อมมาตรฐานการตั้งชื่อ+โฟลเดอร์
+* Dev/Prod แยกชัดเจนผ่าน Docker multi‑stage + docker‑compose + โฟลเดอร์ persist logs/config/certs

+
+**Trust Boundaries**
+
+* Public zone: Internet ↔ Reverse proxy
+* App zone: Reverse proxy ↔ FE/BE containers (internal Docker network)
+* Data zone: Backend ↔ Databases (MariaDB, Postgres) + `/share/dms-data`
+
+---
+
+## 2) Frontend Architecture (Next.js / React)
+
+### 2.1 Stack & Key libs
+
+* **Next.js (App Router)**, **React**, ESM
+* **Tailwind CSS**, **PostCSS**, **shadcn/ui** (components.json)
+* Fetch API (credentials include) → Cookie Auth (HttpOnly)
+
+### 2.2 Directory Layout
+
+```
+/frontend/
+├─ app/
+│  ├─ login/
+│  ├─ dashboard/
+│  ├─ users/
+│  ├─ correspondences/
+│  ├─ health/
+│  └─ layout.tsx / page.tsx (ตาม App Router)
+├─ public/
+├─ Dockerfile (multi-stage: dev/prod)
+├─ package.json
+├─ next.config.js
+└─ ...
+```
+
+### 2.3 Routing & Layouts
+
+* **Public**: `/login`, `/health`
+* **Protected**: `/dashboard`, `/users`, `/correspondences`, ... (client-side guard)
+* เก็บ **middleware.ts (ของเดิม)** เพื่อหลีกเลี่ยง regression; ใช้ client‑guard + server action อย่างระมัดระวัง
+
+### 2.4 Auth Flow (Cookie-based)
+
+1. ผู้ใช้ submit form `/login` → `POST /api/auth/login` (Backend)
+2. Backend set **HttpOnly** cookie (JWT) + `SameSite=Lax/Strict`, `Secure`
+3. หน้า protected เรียก `GET /api/auth/me` เพื่อตรวจสอบสถานะ
+4. หาก 401 → redirect → `/login`
+
+> **CORS/Fetch**: เปิด `credentials: 'include'` ทุกครั้ง, ตั้ง `NEXT_PUBLIC_API_BASE` เป็น origin ของ backend ผ่าน proxy (เช่น `https://lcbp3.np-dms.work`)
+
+### 2.5 UI/UX
+
+* Sea‑blue palette, sidebar พับได้, card‑based KPI
+* ตารางข้อมูลเตรียมรองรับ **server‑side DataTables**
+* shadcn/ui: Button, Card, Badge, Tabs, Dropdown, Tooltip, Switch, etc.
+
+### 2.6 Config & ENV
+
+* `NEXT_PUBLIC_API_BASE` (ex: `https://lcbp3.np-dms.work`)
+* Build output แยก dev/prod; ระวัง EACCES บน QNAP → ใช้ user `node` + ปรับสิทธิ์โวลุ่ม `.next/*`
+
+### 2.7 Error Handling & Observability (FE)
+
+* Global error boundary (app router) + toast/alert patterns
+* Network layer: แยก handler สำหรับ 401/403/500 + retry/backoff ที่จำเป็น
+* Metrics (optional): web‑vitals, UX timing (เก็บฝั่ง n8n หรือ simple logging)
+
+---
+
+## 3) Backend Architecture (Node.js ESM / Express)
+
+### 3.1 Stack & Structure
+
+* Node 20.x, **ESM** modules, **Express**
+* `mysql2/promise`, `jsonwebtoken`, `cookie-parser`, `cors`, `helmet`, `winston/morgan`
+
+```tree
+/backend/
+├─ src/
+│  ├─ index.js               # bootstrap server, CORS, cookies, health
+│  ├─ routes/
+│  │   ├─ auth.js            # /api/auth/* (login, me, logout)
+│  │   ├─ users.js           # /api/users/*
+│  │   ├─ correspondences.js # /api/correspondences/*
+│  │   ├─ drawings.js        # /api/drawings/*
+│  │   ├─ rfas.js            # /api/rfas/*
+│  │   └─ transmittals.js    # /api/transmittals/*
+│  ├─ middleware/
+│  │   ├─ authGuard.js       # verify JWT from cookie
+│  │   ├─ requirePermission.js# RBAC/ABAC enforcement
+│  │   ├─ errorHandler.js
+│  │   └─ requestLogger.js
+│  ├─ db/
+│  │   ├─ pool.js            # createPool, sane defaults
+│  │   └─ models/            # query builders (User, Drawing, ...)
+│  ├─ utils/
+│  │   ├─ hash.js (bcrypt/argon2)
+│  │   ├─ jwt.js
+│  │   ├─ pagination.js
+│  │   └─ responses.js
+│  └─ config/
+│      └─ index.js           # env, constants
+├─ Dockerfile
+└─ package.json
+```
+
+### 3.2 Request Lifecycle
+
+1. `helmet` + `cors` (allow specific origin; credentials true)
+2. `cookie-parser`, `json limit` (e.g., 2MB)
+3. `requestLogger` → trace + response time
+4. Route handler → `authGuard` (protected) → `requirePermission` (per‑route) → Controller
+5. Error bubbles → `errorHandler` (JSON shape, status map)
+
+### 3.3 Auth & RBAC/ABAC
+
+* **JWT** ใน HttpOnly cookie; Claims: `sub` (user_id), `roles`, `exp`
+* **authGuard**: ตรวจ token → แนบ `req.user`
+* **requirePermission**: เช็ค permission ตามเส้นทาง/วิธี; แผนขยาย ABAC (เช่น project scope, owner, doc state)
+* Roles/Permissions ถูก seed ใน SQL; มี **view เมทริกซ์** เพื่อ debug (เช่น `v_role_permission_matrix`)
+
+**ตัวอย่าง pseudo** `requirePermission(permission)`
+
+```js
+export const requirePermission = (perm) => async (req, res, next) => {
+  if (!req.user) return res.status(401).json({ error: 'Unauthenticated' });
+  const ok = await checkPermission(req.user.user_id, perm, req.context);
+  if (!ok) return res.status(403).json({ error: 'Forbidden' });
+  return next();
+};
+```
+
+### 3.4 Database Access & Pooling
+
+* `createPool({ connectionLimit: 10~25, queueLimit: 0, waitForConnections: true })`
+* ใช้ parameterized queries เสมอ; ปรับ `sql_mode` ที่จำเป็นใน `my.cnf`
+
+### 3.5 File Storage & Secure Download
+
+* Root: **/share/dms‑data**
+* โครงโฟลเดอร์: `{module}/{yyyy}/{mm}/{entityId}/` + ชื่อไฟล์ตามมาตรฐาน (เช่น `DRW-<code>-REV-<rev>.pdf`)
+* Endpoint download: ตรวจสิทธิ์ (RBAC/ABAC) → `res.sendFile()`/stream; ป้องกัน path traversal
+* MIME allowlist + size limit + virus scan (optional; ภายหลัง)
+
+### 3.6 Health & Readiness
+
+* `GET /api/health` → `{ ok: true }`
+* (optional) `/api/ready` ตรวจ DB ping + disk space (dms‑data)
+
+### 3.7 Config & ENV (BE)
+
+* `DB_HOST, DB_PORT, DB_USER, DB_PASS, DB_NAME`
+* `JWT_SECRET, COOKIE_NAME, COOKIE_SAMESITE, COOKIE_SECURE`
+* `CORS_ORIGIN, LOG_LEVEL, APP_BASE_URL`
+* `FILE_ROOT=/share/dms-data`
+
+### 3.8 Logging
+
+* Access log (morgan) + App log (winston) → `/share/Container/dms/logs/backend/`
+* รูปแบบ JSON (timestamp, level, msg, reqId) + daily rotation (logrotate/container‑side)
+
+---
+
+## 4) Database (MariaDB 10.11)
+
+### 4.1 Schema Overview (ย่อ)
+
+* **RBAC core**: `users`, `roles`, `permissions`, `user_roles`, `role_permissions`
+* **Domain**: `drawings`, `contracts`, `correspondences`, `rfas`, `transmittals`, `organizations`, `projects`, ...
+* **Audit**: `audit_logs` (แผนขยาย), `deleted_at` (soft delete, แผนงาน)
+
+```
+[users]──<user_roles>──[roles]──<role_permissions>──[permissions]
+   │
+   └── activities/audit_logs (future expansion)
+
+[drawings]──<mapping>──[contracts]
+[rfas]──<links>──[drawings]
+[correspondences] (internal/external flag)
+```
+
+### 4.2 Init SQL Pipeline
+
+1. `01_*_deploy_table_rbac.sql` — สร้างตารางหลักทั้งหมด + RBAC
+2. `02_*_triggers.sql` — บังคับ data rules, auto‑audit fields
+3. `03_*_procedures_handlers.sql` — upsert/bulk handlers (เช่น `sp_bulk_import_contract_dwg`)
+4. `04_*_views.sql` — รายงาน/เมทริกซ์สิทธิ์ (`v_role_permission_matrix`, etc.)
+5. `05_*_seed_data.sql` — ค่าพื้นฐาน domain (project, categories, statuses)
+6. `06_*_seed_users.sql` — บัญชีเริ่มต้น (superadmin, editors, viewers)
+7. `07_*_seed_contract_dwg.sql` — ข้อมูลตัวอย่างแบบสัญญา
+
+### 4.3 Indexing & Performance
+
+* Composite indexes ตามคอลัมน์ filter/sort (เช่น `(project_id, updated_at DESC)`)
+* Full‑text index (optional) สำหรับ advanced search
+* Query plan review (EXPLAIN) + เพิ่ม covering index ตามรายงาน
+
+### 4.4 MySQL/MariaDB Config (my.cnf — แนวทาง)
+
+```
+[mysqld]
+innodb_buffer_pool_size = 4G     # ปรับตาม RAM/QNAP
+innodb_log_file_size    = 512M
+innodb_flush_log_at_trx_commit = 1
+max_connections         = 200
+sql_mode                = STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION
+character-set-server    = utf8mb4
+collation-server        = utf8mb4_unicode_ci
+```
+
+> ปรับค่าให้เหมาะกับ workload จริง + เฝ้าดู IO/CPU ของ QNAP
+
+### 4.5 Backup/Restore
+
+* Logical backup: `mysqldump --routines --triggers --single-transaction`
+* Physical (snapshot QNAP) + schedule ผ่าน n8n/cron
+* เก็บสำเนา off‑NAS (encrypted)
+
+---
+
+## 5) Reverse Proxy & TLS
+
+### 5.1 Nginx (Alpine) — ตัวอย่าง server block
+
+> **สำคัญ:** บนสภาพแวดล้อมนี้ ให้ใช้คนละบรรทัด:
+> `listen 443 ssl;`
+> `http2 on;`
+> หลีกเลี่ยง `listen 443 ssl http2;`
+
+```nginx
+server {
+  listen 80;
+  server_name lcbp3.np-dms.work;
+  return 301 https://$host$request_uri;
+}
+
+server {
+  listen 443 ssl;
+  http2 on;
+  server_name lcbp3.np-dms.work;
+
+  ssl_certificate     /etc/nginx/certs/fullchain.pem;
+  ssl_certificate_key /etc/nginx/certs/privkey.pem;
+  add_header Strict-Transport-Security "max-age=63072000; preload" always;
+
+  # Frontend
+  location / {
+    proxy_pass http://frontend:3000;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+
+  # Next.js static
+  location /_next/ {
+    proxy_pass http://frontend:3000;
+  }
+
+  # Backend API
+  location /api/ {
+    proxy_http_version 1.1;
+    proxy_set_header Connection "";
+    proxy_pass http://backend:3001;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+
+  # phpMyAdmin (sub-path)
+  location /pma/ {
+    proxy_pass http://phpmyadmin:80/;
+  }
+
+  # n8n
+  location /n8n/ {
+    proxy_pass http://n8n:5678/;
+  }
+}
+```
+
+### 5.2 Nginx Proxy Manager (NPM) — Tips
+
+* ระวังอย่าใส่ `proxy_http_version` ซ้ำซ้อน (duplicate directive) ใน Advanced
+* ถ้าต้องแก้ไฟล์ด้านใน NPM → ระวังไฟล์ใน `/data/nginx/proxy_host/*.conf`
+* จัดการ certificate / SAN หลาย sub‑domain ใน UI แต่ mainten ดีเรื่อง symlink/renew
+
+### 5.3 TLS & Certificates
+
+* Let’s Encrypt (HTTP‑01 webroot/standalone) + HSTS
+* QNAP mgmt เปลี่ยนเป็น 8443 → พอร์ต 443 public ว่างสำหรับ Nginx/NPM
+
+---
+
+## 6) Docker Compose Topology
+
+### 6.1 Services (สรุป)
+
+* `frontend` (Next.js) :3000
+* `backend` (Express) :3001
+* `mariadb` (10.11)    :3306 (internal)
+* `phpmyadmin`         :80 (internal)
+* `nginx` or `npm`     :80/443 (published)
+* `n8n`                :5678 (internal)
+* `postgres_n8n` (16-alpine)
+* `pgadmin4`
+
+### 6.2 Volumes & Paths
+
+```
+/share/Container/dms/
+├─ mariadb/data
+├─ mariadb/init/*.sql
+├─ backend/ (code)
+├─ frontend/ (code)
+├─ phpmyadmin/{sessions,tmp,config.user.inc.php}
+├─ nginx/{nginx.conf,dms.conf,certs/}
+├─ n8n, n8n-postgres, n8n-cache
+└─ logs/{backend,frontend,nginx,pgadmin,phpmyadmin,postgres_n8n}
+/share/dms-data  (pdf/dwg storage)
+```
+
+### 6.3 Healthchecks (suggested)
+
+* **backend**: curl `http://localhost:3001/api/health`
+* **frontend**: curl `/health` (simple JSON)
+* **mariadb**: `mysqladmin ping` with credentials
+* **nginx**: `nginx -t` at startup
+
+### 6.4 Security Hardening
+
+* รัน container ด้วย user non‑root (`user: node` สำหรับ FE/BE)
+* จำกัด capabilities; read‑only FS (ยกเว้นโวลุ่มจำเป็น)
+* เฉพาะ backend เมานต์ `/share/dms-data`
+
+---
+
+## 7) Observability, Ops, and Troubleshooting
+
+### 7.1 Logs
+
+* Frontend → `/logs/frontend/*`
+* Backend  → `/logs/backend/*` (app/access/error)
+* Nginx/NPM → `/logs/nginx/*`
+* MariaDB   → default datadir log + slow query (เปิดใน my.cnf หากต้องการ)
+
+### 7.2 Common Issues & Playbooks
+
+* **401 Unauthenticated**: ตรวจ `authGuard` → JWT cookie มี/หมดอายุ → เวลา server/FE sync → CORS `credentials: true`
+* **EACCES Next.js**: สิทธิ์ `.next/*` + run as `node`, โวลุ่ม map ถูก user:group
+* **NPM duplicate directive**: ลบซ้ำ `proxy_http_version` ใน Advanced / ตรวจ `proxy_host/*.conf`
+* **LE cert path/symlink**: ตรวจ `/etc/letsencrypt/live/npm-*` symlink ชี้ถูก
+* **DB field not found**: ตรวจ schema vs code (migration/init SQL) → sync ให้ตรง
+
+### 7.3 Performance Guides
+
+* **Backend**: keep‑alive, gzip/deflate at proxy, pool 10–25, paginate, avoid N+1
+* **Frontend**: prefetch critical routes, cache static, image optimization
+* **DB**: เพิ่ม index จุด filter, analyze query (EXPLAIN), ปรับ buffer pool
+
+---
+
+## 8) Security & Compliance
+
+* **HTTPS only** + HSTS (preload)
+* **CORS**: allow list เฉพาะ FE origin; `Access-Control-Allow-Credentials: true`
+* **Cookie**: HttpOnly, Secure, SameSite=Lax/Strict
+* **Input Validation**: celebrate/zod (optional) + sanitize
+* **Rate limiting**: per IP/route (optional)
+* **AuditLog**: วางแผนเพิ่ม ครอบคลุม CRUD + mapping (actor, action, entity, before/after)
+* **Backups**: DB + `/share/dms-data` + config (encrypted off‑NAS)
+
+---
+
+## 9) Backlog → Architecture Mapping
+
+1. **RBAC Enforcement ครบ** → เติม `requirePermission` ทุก route + test matrix ผ่าน view
+2. **AuditLog ครบ CRUD/Mapping** → trigger + table `audit_logs` + BE hook
+3. **Upload/Download จริงของ Drawing Revisions** → BE endpoints + virus scan (optional)
+4. **Dashboard KPI** → BE summary endpoints + FE cards/charts
+5. **Server‑side DataTables** → paging/sort/filter + indexesรองรับ
+6. **รายงาน Export CSV/Excel/PDF** → BE export endpoints + FE buttons
+7. **Soft delete** (`deleted_at`) → BE filter default scope + restore endpoint
+8. **Validation เข้ม** → celebrate/zod schema + consistent error shape
+9. **Indexing/Perf** → slow query log + EXPLAIN review
+10. **Job/Cron Deadline Alerts** → n8n schedule + SMTP
+
+---
+

+
+| Component | Ports           | Key ENV                                          |
+| --------- | --------------- | ------------------------------------------------ |
+| Nginx/NPM | 80/443 (public) | SSL paths, HSTS                                  |
+| Frontend  | 3000 (internal) | `NEXT_PUBLIC_API_BASE`                           |
+| Backend   | 3001 (internal) | `DB_*`, `JWT_SECRET`, `CORS_ORIGIN`, `FILE_ROOT` |
+| MariaDB   | 3306 (internal) | `MY_CNF`, credentials                            |
+| n8n       | 5678 (internal) | `N8N_*`, webhook URL under `/n8n/`               |
+| Postgres  | 5432 (internal) | n8n DB                                           |
+
+**QNAP mgmt**: 8443 (already moved)
+

+
+## 11) Sample Snippets
+
+### 11.1 Backend CORS (credentials)
+
+```js
+app.use(cors({
+  origin: ['https://lcbp3.np-dms.work'],
+  credentials: true,
+}));
+```
+
+### 11.2 Secure Download (guarded)
+
+```js
+router.get('/files/:module/:id/:filename', authGuard, requirePermission('file.read'), async (req, res) => {
+  const { module, id, filename } = req.params;
+  // 1) ABAC: verify user can access this module/entity
+  const ok = await canReadFile(req.user.user_id, module, id);
+  if (!ok) return res.status(403).json({ error: 'Forbidden' });
+
+  const abs = path.join(FILE_ROOT, module, id, filename);
+  if (!abs.startsWith(FILE_ROOT)) return res.status(400).json({ error: 'Bad path' });
+  return res.sendFile(abs);
+});
+```
+
+### 11.3 Healthcheck
+
+```js
+router.get('/health', (req, res) => res.json({ ok: true }));
+```
+
+---
+
+## 12) Deployment Workflow (Suggested)
+
+1. Git (Gitea) branch strategy `feature/*` → PR → main
+2. Build images (dev/prod) via Dockerfile multi‑stage; pin Node/MariaDB versions
+3. `docker compose up -d --build` จาก `/share/Container/dms`
+4. Validate: `/health`, `/api/health`, login roundtrip
+5. Monitor logs + baseline perf; run SQL smoke tests (views/triggers/procs)
+
+---
+
+## 13) Appendix
+
+* **Naming conventions**: snake_case DB, camelCase JS
+* **Timezones**: store UTC in DB; display in app TZ (+07:00)
+* **Character set**: UTF‑8 (`utf8mb4_unicode_ci`)
+* **Large file policy**: size limit (e.g., 50–200MB), allowlist extensions
+* **Retention**: archive strategy for old revisions (optional)
+
+---
+
+> หากต้องการ เวอร์ชัน **README.md พร้อมโค้ดตัวอย่าง compose/nginx** จัดรูปแบบให้นำไปวางใน repo ได้ทันที แจ้งได้เลยว่าจะให้แตกไฟล์เป็น `/docs/Architecture.md` + `/nginx/dms.conf` + `/docker-compose.yml` template หรือรูปแบบอื่นที่สะดวกต่อการใช้งานของทีม

+
+## 🛠️ 1. DMS Architecture Deep Dive (Backend + Frontend)
+
+### 1.1 Executive Summary
+
+- Reverse proxy (Nginx/NPM) เผยแพร่ Frontend (Next.js) และ Backend (Node.js/Express) ผ่าน HTTPS (HSTS)
+- Backend เชื่อม MariaDB 10.11 (ข้อมูลหลัก DMS) และแยก n8n + Postgres 16 สำหรับ workflow
+- RBAC/ABAC ถูกบังคับใช้งานใน middleware + มีชุด SQL (tables → triggers → procedures → views → seed)
+- ไฟล์จริง (PDF/DWG) เก็บนอก webroot ที่ /share/dms‑data พร้อมมาตรฐานการตั้งชื่อ+โฟลเดอร์
+- Dev/Prod แยกชัดเจนผ่าน Docker multi‑stage + docker‑compose + โฟลเดอร์ persist logs/config/certs
+

+```
+
+==Trust Boundaries==
+
+- Public zone: Internet ↔ Reverse proxy
+- App zone: Reverse proxy ↔ FE/BE containers (internal Docker network)
+- # Data zone: Backend ↔ Databases (MariaDB, Postgres) + /share/dms-data
+
+### 1.3 Frontend: Next.js (ESM) / React.js
+
+#### 1.3.1 Stack & Key libs
+
+- Next.js (App Router), React, ESM
+- Tailwind CSS, PostCSS, shadcn/ui (components.json)
+- Fetch API (credentials include) → Cookie Auth (HttpOnly)
+
+#### 1.3.2 Directory Layout
+
+```text
+/frontend/
+├─ app/
+│  ├─ login/
+│  ├─ dashboard/
+│  ├─ users/
+│  ├─ correspondences/
+│  ├─ health/
+│  └─ layout.tsx / page.tsx (ตาม App Router)
+├─ public/
+├─ Dockerfile (multi-stage: dev/prod)
+├─ package.json
+├─ next.config.js
+└─ ...
+```
+
+#### 1.3.3 Routing & Layouts
+
+- Public /login, /health
+- Protected: /dashboard, /users, /correspondences, ... (client-side guard)
+- เก็บ middleware.ts (ของเดิม) เพื่อหลีกเลี่ยง regression; ใช้ client‑guard + server action อย่างระมัดระวัง
+
+#### 1.3.4 Auth Flow (Cookie-based)
+
+1. ผู้ใช้ submit form /login → POST /api/auth/login (Backend)
+2. Backend set HttpOnly cookie (JWT) + SameSite=Lax/Strict, Secure
+3. หน้า protected เรียก GET /api/auth/me เพื่อตรวจสอบสถานะ
+4. หาก 401 → redirect → /login
+
+**CORS/Fetch**: เเปิด credentials: 'include' ทุกครั้ง, ตั้ง NEXT_PUBLIC_API_BASE เป็น origin ของ backend ผ่าน proxy (เช่น https://lcbp3.np-dms.work)
+
+#### 1.3.5 UI/UX
+
+- Sea‑blue palette, sidebar พับได้, card‑based KPI
+- ตารางข้อมูลเตรียมรองรับ server‑side DataTables\*\*
+- shadcn/ui: Button, Card, Badge, Tabs, Dropdown, Tooltip, Switch, etc.
+
+#### 1.3.6 Config & ENV
+
+- NEXT_PUBLIC_API_BAS (ex: https://lcbp3.np-dms.work)
+- Build output แยก dev/prod; ระวัง EACCES บน QNAP → ใช้ user node + ปรับสิทธิ์โวลุ่ม .next/\*
+
+#### 1.3.7 Error Handling & Observability (FE)
+
+- Global error boundary (app router) + toast/alert patterns
+- Network layer: แยก handler สำหรับ 401/403/500 + retry/backoff ที่จำเป็น
+- Metrics (optional): web‑vitals, UX timing (เก็บฝั่ง n8n หรือ simple logging)
+
+---
+
+### 1.4 Backend Architecture (Node.js ESM / Express)
+
+#### 1.4.1 Stack & Structure
+
+- Node 20.x, ESM modules, Express\*\*
+- mysql2/promise, jsonwebtoken, cookie-parser, cors, helmet, winston/morgan
+
+```text
+/backend/
+├─ src/
+│  ├─ index.js               # bootstrap server, CORS, cookies, health

+│  └─ config/
+│      └─ index.js           # env, constants
+├─ Dockerfile
+└─ package.json
+```
+
+#### 1.4.2 Request Lifecycle
+
+1. helmet + cors (allow specific origin; credentials true)
+2. cookie-parser, json limit (e.g., 2MB)
+3. requestLogger → trace + response time
+4. Route handler → authGuard (protected) → requirePermission (per‑route) → Controller
+5. Error bubbles → errorHandler (JSON shape, status map)
+
+#### 1.4.3 Auth & RBAC/ABAC
+
+- JWT ใน HttpOnly cookie; Claims: sub (user_id), roles, exp
+- authGuard: ตรวจ token → แนบ req.user
+- requirePermission: เช็ค permission ตามเส้นทาง/วิธี; แผนขยาย ABAC (เช่น project scope, owner, doc state)
+- Roles/Permissions ถูก seed ใน SQL; มี view เมทริกซ์ เพื่อ debug (เช่น v_role_permission_matrix)
+
+\*\*ตัวอย่าง pseudo requirePermission(permission)
+
+```js
+export const requirePermission = (perm) => async (req, res, next) => {
+  if (!req.user) return res.status(401).json({ error: "Unauthenticated" });
+  const ok = await checkPermission(req.user.user_id, perm, req.context);
+  if (!ok) return res.status(403).json({ error: "Forbidden" });
+  return next();
+};
+```
+
+#### 1.4.4 Database Access & Pooling
+
+- createPool({ connectionLimit: 10~25, queueLimit: 0, waitForConnections: true })
+- ใช้ parameterized queries เสมอ; ปรับ sql_mode ที่จำเป็นใน my.cnf
+
+#### 1.4.5 File Storage & Secure Download
+
+- Root: /share/dms‑data
+- โครงโฟลเดอร์: {module}/{yyyy}/{mm}/{entityId}/ + ชื่อไฟล์ตามมาตรฐาน (เช่น DRW-code-REV-rev.pdf)
+- Endpoint download: ตรวจสิทธิ์ (RBAC/ABAC) → res.sendFile()/stream; ป้องกัน path traversal
+- MIME allowlist + size limit + virus scan (optional; ภายหลัง)
+
+#### 1.4.6 Health & Readiness
+
+- GET /api/health → { ok: true }
+- (optional) /api/ready ตรวจ DB ping + disk space (dms‑data)
+
+#### 1.4.7 Config & ENV (BE)
+
+- DB_HOST, DB_PORT, DB_USER, DB_PASS, DB_NAME
+- JWT_SECRET, COOKIE_NAME, COOKIE_SAMESITE, COOKIE_SECURE
+- CORS_ORIGIN, LOG_LEVEL, APP_BASE_URL
+- FILE_ROOT=/share/dms-data
+
+#### 1.4.8 Logging
+
+- Access log (morgan) + App log (winston) → /share/Container/dms/logs/backend/
+- รูปแบบ JSON (timestamp, level, msg, reqId) + daily rotation (logrotate/container‑side)
+
+### 1.5 Database (MariaDB 10.11)
+
+#### 1.5.1 Schema Overview (ย่อ)
+
+- RBAC core: users, roles, permissions, user_roles, role_permissions
+- Domain: drawings, contracts, correspondences, rfas, transmittals, organizations, projects, ...
+- Audit: audit_logs (แผนขยาย), deleted_at (soft delete, แผนงาน)
+
+```text
+[users]──<user_roles>──[roles]──<role_permissions>──[permissions]
+   │
+   └── activities/audit_logs (future expansion)
+
+[drawings]──<mapping>──[contracts]
+[rfas]──<links>──[drawings]
+[correspondences] (internal/external flag)
+```
+
+#### 1.5.2 Init SQL Pipeline
+
+1. 01\_\*\_deploy_table_rbac.sql — สร้างตารางหลักทั้งหมด + RBAC
+2. 02\_\*\_triggers.sql — บังคับ data rules, auto‑audit fields
+3. 03\_\*\_procedures_handlers.sql — upsert/bulk handlers (เช่น sp_bulk_import_contract_dwg)
+4. 04\_\*\_views.sql — รายงาน/เมทริกซ์สิทธิ์ (v_role_permission_matrix, etc.)
+5. 05\_\*\_seed_data.sql — ค่าพื้นฐาน domain (project, categories, statuses)
+6. 06\_\*\_seed_users.sql — บัญชีเริ่มต้น (superadmin, editors, viewers)
+7. 07\_\*\_seed_contract_dwg.sql — ข้อมูลตัวอย่างแบบสัญญา
+
+#### 1.5.3 Indexing & Performance
+
+- Composite indexes ตามคอลัมน์ filter/sort (เช่น (project_id, updated_at DESC))
+- Full‑text index (optional) สำหรับ advanced search
+- Query plan review (EXPLAIN) + เพิ่ม covering index ตามรายงาน
+
+#### 1.5.4 MySQL/MariaDB Config (my.cnf — แนวทาง)
+
+```conf
+[mysqld]
+innodb_buffer_pool_size = 4G     # ปรับตาม RAM/QNAP
+innodb_log_file_size    = 512M
+innodb_flush_log_at_trx_commit = 1
+max_connections         = 200
+sql_mode                = STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION
+character-set-server    = utf8mb4
+collation-server        = utf8mb4_unicode_ci
+```
+
+> ปรับค่าให้เหมาะกับ workload จริง + เฝ้าดู IO/CPU ของ QNAP
+
+#### 1.5.5 Backup/Restore
+
+- Logical backup: mysqldump --routines --triggers --single-transaction
+- Physical (snapshot QNAP) + schedule ผ่าน n8n/cron
+- เก็บสำเนา off‑NAS (encrypted)
+
+### 1.6 Reverse Proxy & TLS
+
+#### 1.6.1 Nginx (Alpine) — ตัวอย่าง server block
+
+> สำคัญ: บนสภาพแวดล้อมนี้ ให้ใช้คนละบรรทัด:  
+> listen 443 ssl;
+> http2 on;
+> หลีกเลี่ยง listen 443 ssl http2;
+
+```conf
+server {
+  listen 80;
+  server_name lcbp3.np-dms.work;
+  return 301 https://$host$request_uri;
+}
+
+server {
+  listen 443 ssl;
+  http2 on;
+  server_name lcbp3.np-dms.work;
+
+  ssl_certificate     /etc/nginx/certs/fullchain.pem;
+  ssl_certificate_key /etc/nginx/certs/privkey.pem;
+  add_header Strict-Transport-Security "max-age=63072000; preload" always;
+
+  # Frontend
+  location / {
+    proxy_pass http://frontend:3000;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+
+  # Next.js static
+  location /_next/ {
+    proxy_pass http://frontend:3000;
+  }
+
+  # Backend API
+  location /api/ {
+    proxy_http_version 1.1;
+    proxy_set_header Connection "";
+    proxy_pass http://backend:3001;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-Proto $scheme;
+  }
+
+  # phpMyAdmin (sub-path)
+  location /pma/ {
+    proxy_pass http://phpmyadmin:80/;
+  }
+
+  # n8n
+  location /n8n/ {
+    proxy_pass http://n8n:5678/;
+  }
+}
+```
+
+#### 1.6.2 Nginx Proxy Manager (NPM) — Tips
+
+- ระวังอย่าใส่ proxy_http_version ซ้ำซ้อน (duplicate directive) ใน Advanced
+- ถ้าต้องแก้ไฟล์ด้านใน NPM → ระวังไฟล์ใน /data/nginx/proxy_host/\*.conf
+- จัดการ certificate / SAN หลาย sub‑domain ใน UI แต่ mainten ดีเรื่อง symlink/renew
+
+#### 1.6.3 TLS & Certificates
+
+- Let’s Encrypt (HTTP‑01 webroot/standalone) + HSTS
+- QNAP mgmt เปลี่ยนเป็น 8443 → พอร์ต 443 public ว่างสำหรับ Nginx/NPM
+
+### 1.7 Docker Compose Topology
+
+#### 1.7.1 Services (สรุป)
+
+- frontend (Next.js) :3000
+- backend (Express) :3001
+- mariadb (10.11) :3306 (internal)
+- phpmyadmin :80 (internal)
+- nginx or npm :80/443 (published)
+- n8n :5678 (internal)
+- postgres_n8n (16-alpine)
+- pgadmin4
+
+#### 1.7.2 Volumes & Paths
+
+```text
+/share/Container/dms/
+├─ mariadb/data
+├─ mariadb/init/*.sql
+├─ backend/ (code)
+├─ frontend/ (code)
+├─ phpmyadmin/{sessions,tmp,config.user.inc.php}
+├─ nginx/{nginx.conf,dms.conf,certs/}
+├─ n8n, n8n-postgres, n8n-cache
+└─ logs/{backend,frontend,nginx,pgadmin,phpmyadmin,postgres_n8n}
+/share/dms-data  (pdf/dwg storage)
+```
+
+#### 1.7.3 Healthchecks (suggested)
+
+- backend:
+
+  ```sh
+  curl http://localhost:3001/api/health
+  ```
+
+- frontend: curl /health (simple JSON)
+- mariadb: mysqladmin ping with credentials
+- nginx: nginx -t at startup
+
+#### 1.7.4 Security Hardening
+
+- รัน container ด้วย user non‑root (user: node สำหรับ FE/BE)
+- จำกัด capabilities; read‑only FS (ยกเว้นโวลุ่มจำเป็น)
+- เฉพาะ backend เมานต์ /share/dms-data
+
+### 1.8 Observability, Ops, and Troubleshooting
+
+#### 1.8.1 Logs
+
+- Frontend → /logs/frontend/\*
+- Backend → /logs/backend/\* (app/access/error)
+- Nginx/NPM → /logs/nginx/\*
+- MariaDB → default datadir log + slow query (เปิดใน my.cnf หากต้องการ)
+
+#### 1.8.2 Common Issues & Playbooks
+
+- 401 Unauthenticated: ตรวจ authGuard → JWT cookie มี/หมดอายุ → เวลา server/FE sync → CORS credentials: true
+- EACCES Next.js: สิทธิ์ .next/\* + run as`node, โวลุ่ม map ถูก user:group
+- NPM duplicate directive: ลบซ้ำ proxy_http_version ใน Advanced / ตรวจ proxy_host/\*.conf
+- LE cert path/symlink: ตรวจ /etc/letsencrypt/live/npm-\* symlink ชี้ถูก
+- DB field not found: ตรวจ schema vs code (migration/init SQL) → sync ให้ตรง
+
+#### 1.8.3 Performance Guides
+
+- Backend: keep‑alive, gzip/deflate at proxy, pool 10–25, paginate, avoid N+1
+- Frontend: prefetch critical routes, cache static, image optimization
+- DB: เพิ่ม index จุด filter, analyze query (EXPLAIN), ปรับ buffer pool
+
+### 1.9 Security & Compliance
+
+- HTTPS only + HSTS (preload)
+- CORS: allow list เฉพาะ FE origin; Access-Control-Allow-Credentials: true
+- Cookie: HttpOnly, Secure, SameSite=Lax/Strict
+- Input Validation: celebrate/zod (optional) + sanitize
+- Rate limiting: per IP/route (optional)
+- AuditLog: วางแผนเพิ่ม ครอบคลุม CRUD + mapping (actor, action, entity, before/after)
+- Backups: DB + /share/dms-data + config (encrypted off‑NAS)

+### 1.10 Backlog → Architecture Mapping
+
+1. RBAC Enforcement ครบ → เติม requirePermission ทุก route + test matrix ผ่าน view
+2. AuditLog ครบ CRUD/Mapping → trigger + table audit_logs + BE hook
+3. Upload/Download จริงของ Drawing Revisions → BE endpoints + virus scan (optional)
+4. Dashboard KPI → BE summary endpoints + FE cards/charts
+5. Server‑side DataTables → paging/sort/filter + indexesรองรับ
+6. รายงาน Export CSV/Excel/PDF → BE export endpoints + FE buttons
+7. Soft delete (deleted_at) → BE filter default scope + restore endpoint
+8. Validation เข้ม → celebrate/zod schema + consistent error shape
+9. Indexing/Perf → slow query log + EXPLAIN review
+10. Job/Cron Deadline Alerts → n8n schedule + SMTP
+
+### 1.11 Port & ENV Matrix (Quick Ref)
+
+| Component | Ports | Key ENV |

+
+### 1.12 Sample Snippets
+
+#### 1.12.1 Backend CORS (credentials)
+
+```js
+app.use(
+  cors({
+    origin: ["https://lcbp3.np-dms.work"],
+    credentials: true,
+  })
+);
+```
+
+#### 1.12.2 Secure Download (guarded)
+
+```js
+router.get(
+  "/files/:module/:id/:filename",
+  authGuard,
+  requirePermission("file.read"),
+  async (req, res) => {
+    const { module, id, filename } = req.params;
+    // 1) ABAC: verify user can access this module/entity
+    const ok = await canReadFile(req.user.user_id, module, id);
+    if (!ok) return res.status(403).json({ error: "Forbidden" });
+
+    const abs = path.join(FILE_ROOT, module, id, filename);
+    if (!abs.startsWith(FILE_ROOT))
+      return res.status(400).json({ error: "Bad path" });
+    return res.sendFile(abs);
+  }
+);
+```
+
+#### 1.12.3 Healthcheck
+
+```js
+router.get("/health", (req, res) => res.json({ ok: true }));
+```
+
+### 13 Deployment Workflow (Suggested)
+
+1. Git (Gitea) branch strategy feature/\* → PR → main
+2. Build images (dev/prod) via Dockerfile multi‑stage; pin Node/MariaDB versions
+3. docker compose up -d --build จาก /share/Container/dms
+4. Validate: /health, /api/health, login roundtrip
+5. Monitor logs + baseline perf; run SQL smoke tests (views/triggers/procs)
+
+### 14 Appendix

+## วิธีสร้าง package-lock.json ด้วย Docker
+
+### 1. เช็ค uid:gid ของโฟลเดอร์โปรเจกต์บน QNAP
+
+stat -c "%u:%g" .
+
+### 2. ใช้ค่าที่ได้มาแทน UID:GID
+
+```bash
+docker run --rm \
+  -v "/share/Container/dms/frontend:/app" -w /app \
+  --user UID:GID -e HOME=/tmp \
+  node:20-alpine sh -lc 'mkdir -p /tmp && npm install --package-lock-only --ignore-scripts'
+```
+
+สร้าง package-lock.json โดย ไม่ติดตั้ง node_modules
+
+--user $(id -u):$(id -g) ทำให้ไฟล์ที่ได้เป็นเจ้าของโดยยูสเซอร์ปัจจุบัน (กันปัญหา root-owned)
+
+## ขั้นตอน Build บน QNAP
+
+docker compose -f docker-backend-build.yml build --no-cache 2>&1 | tee backend_build.log
+
+## สำหรับ build local
+
+cd backend
+docker build -t dms-backend:dev --target dev .
