echo ========================================
echo Fix Node.js Version for ETest Project
echo ========================================
echo.

echo [!] Current Node.js version is NOT compatible!
echo.
echo Project Requirements:
echo   - Vue 2.6.12 + Vue CLI 4.4.6
echo   - Node.js: 14.x or 16.x (recommended)
echo   - Your current version: 22.x (TOO NEW)
echo.
echo ========================================
echo Option 1: Install NVM and Node.js 16
echo ========================================
echo.
echo Step 1: Download and install nvm-windows
echo   URL: https://github.com/coreybutler/nvm-windows/releases
echo   Download: nvm-setup.exe
echo.
echo Step 2: Open a NEW terminal after installing nvm
echo.
echo Step 3: Run these commands:
echo   nvm install 16.20.2
echo   nvm use 16.20.2
echo   node -v  ^(should show v16.20.2^)
echo.
echo Step 4: Reinstall dependencies:
echo   cd C:\PPRO\ETest-Vue-FastAPI\ruoyi-fastapi-frontend
echo   rmdir /s /q node_modules
echo   del package-lock.json
echo   npm install
echo   npm run dev
echo.
echo ========================================
echo Option 2: Use Docker (No Node.js install)
echo ========================================
echo.
echo Run frontend in Docker container:
echo   docker run -it ^
echo     -v C:\PPRO\ETest-Vue-FastAPI\ruoyi-fastapi-frontend:/app ^
echo     -w /app ^
echo     -p 5173:5173 ^
echo     node:16-alpine ^
echo     sh -c "npm install ^&^& npm run dev"
echo.
echo ========================================
echo Option 3: Download Node.js 16 Portable
echo ========================================
echo.
echo Step 1: Download Node.js 16.20.2
echo   URL: https://nodejs.org/dist/v16.20.2/node-v16.20.2-win-x64.zip
echo.
echo Step 2: Extract to C:\nodejs16\
echo.
echo Step 3: Use full path:
echo   C:\nodejs16\node.exe -v
echo   C:\nodejs16\npm.exe install
echo   C:\nodejs16\npm.exe run dev
echo.

echo ========================================
echo Quick Fix: Try with --legacy-peer-deps
echo ========================================
echo.
echo This may work with Node.js 22:
echo   cd C:\PPRO\ETest-Vue-FastAPI\ruoyi-fastapi-frontend
echo   npm install --legacy-peer-deps
echo   npm run dev
echo.
echo [*] Attempting quick fix now...
echo.

cd /d C:\PPRO\ETest-Vue-FastAPI\ruoyi-fastapi-frontend

echo [*] Removing node_modules...
rmdir /s /q node_modules 2>nul
del package-lock.json 2>nul

echo [*] Installing with --legacy-peer-deps...
npm install --legacy-peer-deps

echo.
if %errorlevel% equ 0 (
    echo [OK] Install successful!
    echo [*] Testing build...
    npm run build:prod
    
    if %errorlevel% equ 0 (
        echo [OK] Build successful!
        echo [*] Starting dev server...
        npm run dev
    ) else (
        echo [!] Build failed - Node.js 22 is not compatible
        echo [*] Please use Option 1 or 2 above
    )
) else (
    echo [!] Install failed
    echo [*] Please use Option 1 or 2 above
)
