# === STEP 1: Generate Components ===
# cd /share/Container/dms
# UID=$(id -u) GID=$(id -g) docker compose -f generate-shadcn-components.yml run --rm setup-shadcn

# === STEP 2: ตรวจสอบไฟล์ ===
# cd frontend
# echo "📁 Components created:"
# ls -la components/ui/ 2>/dev/null || echo "⚠️  No components/ui/ directory"
# ls -la lib/ 2>/dev/null || echo "⚠️  No lib/ directory"
# ls -la components.json 2>/dev/null || echo "⚠️  No components.json"

# === STEP 3: Commit to Git ===
# git add components/ lib/ components.json
# git status
# git commit -m "Add shadcn/ui components and utilities"

# === STEP 4: Build Docker Image ===
# cd /share/Container/dms
# docker compose -f docker-frontend-build.yml build --no-cache
# docker compose -f docker-frontend-build.yml build --no-cache 2>&1 | tee build.log

# === ต่อไปที่ต้องเพิ่ม component ใหม่:
# docker run --rm -v "$PWD:/app" -w /app node:24-alpine \
#   npx shadcn@latest add dialog

# แล้ว commit
# git add components/ui/dialog.jsx
# git commit -m "Add dialog component"
