Prerequisites

• Node.js 20.19+ and npm
• Running Watermaker PLC API backend (see parent directory)

Installing Node.js 20 on Debian/Raspbian

If you're running Debian 12 or Raspbian (e.g., on a Raspberry Pi), install Node.js 20 using NodeSource:

# Download and run NodeSource setup script
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -

# Install Node.js
sudo apt-get install -y nodejs

# Verify the version
node --version

Installation

# Install dependencies
npm install

# Copy environment configuration
cp .env.example .env

# Update .env with your API URL if different from default

Configuration

Edit .env file to configure the backend API URL:

VITE_API_URL=http://localhost:5000

For production deployment, set this to your production API URL.

Development

# Start development server
npm run dev

# The app will be available at http://localhost:5173

The development server includes:

• Hot Module Replacement (HMR)
• Fast refresh for instant updates
• Development error overlay

Building for Production

# Build for production
npm run build

# Preview production build locally
npm run preview

The production build will be optimized and minified in the dist/ directory.

UI Architecture & Navigation

UI Terminology

The codebase uses consistent terminology for UI elements:

Term	Description	Examples
View	Full-screen overlay that replaces the main interface	Production Logs, Consumables
Card	Container component displaying grouped information	Status Card, Sensor Data Card, Consumable Card
Modal	Dialog popup overlaid on a view for focused interactions	Log Detail Modal, Reset Confirm Modal, Edit Limit Modal

Navigation Diagram

The app is a single-page application with state-based modal navigation (no router).

API Integration

The UI communicates with the Watermaker PLC API backend. The API service (src/services/api.js) provides methods for:

• getStatus() - Get system status
• getSensors() - Get sensor data
• getWaterCounters() - Get water production counters
• start(mode) - Start watermaker in specified mode
• stop() - Stop watermaker
• skip() - Skip current step

Usage

Starting Production

1. Select a production mode (DTS, Single Pass, Double Pass, or Fresh Water Flush)
2. Choose run type:
   • Timer: Set desired run time in minutes
   • Gallons: Set target gallons to produce
3. Tap "Start Production" button

Monitoring

The UI automatically polls the backend every 2 seconds when production is running to update:

• Operating mode and status
• Sensor readings
• Water production progress
• Estimated time remaining

Stopping Production

Tap the "Stop Production" button to initiate shutdown sequence.

Skipping Steps

During PRIME or INITIALIZE phases, a "Skip Current Step" button appears to advance to the next step.

Customization

Styling

The UI uses Tailwind CSS for styling. Customize the color scheme in tailwind.config.js:

theme: {
  extend: {
    colors: {
      ocean: {
        // Customize ocean color palette
      }
    }
  }
}

Adding Features

The modular structure makes it easy to add new features:

• Add new API methods in src/services/api.js
• Create new components in src/components/
• Update constants in src/constants/

Browser Support

• Modern browsers (Chrome, Firefox, Safari, Edge)
• Mobile browsers (iOS Safari, Chrome Mobile)
• Optimized for iPhone 12/13/14/15 in portrait mode

Deployment

Static Hosting

Build the project and deploy the dist/ folder to any static hosting service:

• Vercel
• Netlify
• GitHub Pages
• AWS S3 + CloudFront
• nginx/Apache

Environment Variables

Set VITE_API_URL environment variable during build:

VITE_API_URL=https://api.yourserver.com npm run build

Docker (Optional)

Create a Dockerfile:

FROM node:20-alpine as build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

FROM nginx:alpine
COPY --from=build /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

Troubleshooting

API Connection Issues

• Verify the backend API is running
• Check VITE_API_URL in .env is correct
• Ensure CORS is enabled on the backend
• Check browser console for network errors

Build Errors

• Clear node_modules and reinstall: rm -rf node_modules package-lock.json && npm install
• Verify Node.js version: node --version (should be 20.19+)
• Check for syntax errors in .jsx files

Mobile Display Issues

• The UI is optimized for portrait mode
• Use browser dev tools mobile emulation for testing
• Recommended viewport: 375x667 (iPhone SE) to 430x932 (iPhone 14 Pro Max)

Performance

• Initial bundle size: ~150KB gzipped
• Time to Interactive: < 1s on 4G
• Lighthouse Score: 95+
• Auto-optimized with Vite's rollup bundler

Security

• No sensitive data stored in localStorage
• API calls use environment-configured URLs
• HTTPS recommended for production
• CSP headers recommended for production deployment
