Replaced REST API dependency with @valknarthing/pastel-wasm (130KB) for complete browser-based color operations. The application is now fully static (2.2MB total) with zero network latency and offline support. **Key Changes:** 1. **WASM Integration:** - Added @valknarthing/pastel-wasm dependency (0.1.0) - Created lib/api/wasm-client.ts wrapper matching API interface - Updated lib/api/client.ts to use WASM client by default - All 18 color operations now run locally in browser 2. **Static Export Configuration:** - Changed next.config.ts output from 'standalone' to 'export' - Disabled image optimization for static export - Removed API proxy route (app/api/pastel/[...path]/route.ts) - Updated package.json scripts (removed dev:api, added serve) 3. **Docker Optimization:** - Migrated from Node.js standalone to nginx-alpine - Created nginx.conf with SPA routing and WASM mime types - Updated Dockerfile for static file serving - Reduced image size from ~150MB to ~25MB - Changed port from 3000 to 80 (standard HTTP) - Simplified docker-compose.yml (removed pastel-api service) 4. **Documentation Updates:** - Updated README.md with WASM benefits and deployment options - Added Key Benefits section highlighting zero-latency features - Rewrote deployment section for static hosting platforms - Updated CLAUDE.md tech stack and architecture - Removed obsolete docs: DEV_SETUP.md, DOCKER.md, IMPLEMENTATION_PLAN.md **Benefits:** - 🚀 Zero Latency - All operations run locally via WebAssembly - 📱 Offline First - Works completely offline after initial load - 🌐 No Backend - Fully static, deploy anywhere - ⚡ Fast - Native-speed color operations in browser - 📦 Small - 2.2MB total (130KB WASM, 2.07MB HTML/CSS/JS) **Deployment:** Can now be deployed to any static hosting platform: - Vercel, Netlify, Cloudflare Pages (zero config) - GitHub Pages, S3, CDN - Self-hosted nginx/Apache - Docker (optional, nginx-based) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Development Setup
|
||||
|
||||
## Running the Application
|
||||
|
||||
This application requires both the **UI** (Next.js) and the **API** (Rust) to be running.
|
||||
|
||||
### Quick Start
|
||||
|
||||
**Option 1: Run both together (recommended)**
|
||||
```bash
|
||||
pnpm dev:all
|
||||
```
|
||||
|
||||
**Option 2: Run separately in different terminals**
|
||||
|
||||
Terminal 1 - API:
|
||||
```bash
|
||||
pnpm dev:api
|
||||
# or
|
||||
cd ../pastel-api && cargo run
|
||||
```
|
||||
|
||||
Terminal 2 - UI:
|
||||
```bash
|
||||
pnpm dev
|
||||
```
|
||||
|
||||
## Ports
|
||||
|
||||
- **UI (Next.js)**: http://localhost:3000
|
||||
- **API (Rust)**: http://localhost:3001
|
||||
|
||||
## API Setup
|
||||
|
||||
The Pastel API must be running on port 3001 for the UI to work. If you see "Failed to lighten color!" or 404 errors, it means the API is not running.
|
||||
|
||||
### First Time API Setup
|
||||
|
||||
```bash
|
||||
cd ../pastel-api
|
||||
|
||||
# Build the API
|
||||
cargo build --release
|
||||
|
||||
# Run the API
|
||||
cargo run
|
||||
```
|
||||
|
||||
The API will start on `http://localhost:3001` and the UI will automatically connect to it.
|
||||
|
||||
## Environment Files
|
||||
|
||||
- **UI**: `.env.local` - Sets `NEXT_PUBLIC_API_URL=http://localhost:3001`
|
||||
- **API**: `../pastel-api/.env` - Sets `PORT=3001`
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### API not responding (404 errors)
|
||||
|
||||
**Problem**: UI shows "Failed to lighten color!" or console shows 404 errors
|
||||
|
||||
**Solution**:
|
||||
1. Check if API is running: `curl http://localhost:3001/api/v1/health`
|
||||
2. If not running, start it: `cd ../pastel-api && cargo run`
|
||||
3. Check the API `.env` file has `PORT=3001`
|
||||
|
||||
### Port already in use
|
||||
|
||||
**Problem**: Error: "Address already in use"
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Find what's using the port
|
||||
lsof -i :3000 # for UI
|
||||
lsof -i :3001 # for API
|
||||
|
||||
# Kill the process or use different ports
|
||||
```
|
||||
|
||||
### API build errors
|
||||
|
||||
**Problem**: Cargo build fails
|
||||
|
||||
**Solution**:
|
||||
1. Ensure Rust is installed: `rustc --version`
|
||||
2. Update Rust: `rustup update`
|
||||
3. Check `../pastel-api/Cargo.toml` for dependencies
|
||||
|
||||
## Features Available
|
||||
|
||||
Once both UI and API are running, you can access:
|
||||
|
||||
- **Playground**: http://localhost:3000/playground - Color manipulation with history
|
||||
- **Harmony Palettes**: http://localhost:3000/palettes/harmony - Generate color harmonies
|
||||
- **Distinct Colors**: http://localhost:3000/palettes/distinct - Visually distinct colors
|
||||
- **Gradient Creator**: http://localhost:3000/palettes/gradient - Color gradients

# Docker Deployment Guide
|
||||
|
||||
## Runtime Configuration
|
||||
|
||||
This application uses a **Next.js API proxy** pattern to allow runtime configuration without rebuilding the Docker image.
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Client** makes requests to `/api/pastel/*`
|
||||
2. **Next.js API Route** (`app/api/pastel/[...path]/route.ts`) proxies requests to the backend
|
||||
3. **Backend API URL** is read from `PASTEL_API_URL` environment variable at runtime
|
||||
|
||||
This means you can change the backend API URL by simply restarting the container with a different environment variable - **no rebuild required!**
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Using Docker Compose
|
||||
|
||||
```bash
|
||||
# Start both UI and API
|
||||
docker-compose up -d
|
||||
|
||||
# The UI will automatically connect to the API container
|
||||
# (configured via PASTEL_API_URL=http://pastel-api:3001)
|
||||
```
|
||||
|
||||
### Using Docker Run
|
||||
|
||||
```bash
|
||||
# Build the image once
|
||||
docker build -t pastel-ui .
|
||||
|
||||
# Run with default settings (expects API at http://localhost:3001)
|
||||
docker run -p 3000:3000 pastel-ui
|
||||
|
||||
# Run with custom API URL (no rebuild needed!)
|
||||
docker run -p 3000:3000 \
|
||||
-e PASTEL_API_URL=http://my-api-server:3001 \
|
||||
pastel-ui
|
||||
|
||||
# Run with external API
|
||||
docker run -p 3000:3000 \
|
||||
-e PASTEL_API_URL=https://api.example.com \
|
||||
pastel-ui
|
||||
```
|
||||
|
||||
## Environment Variables
|
||||
|
||||
### Server-Side (Runtime Configuration)
|
||||
|
||||
| Variable | Description | Default | Example |
|
||||
|----------|-------------|---------|---------|
|
||||
| `PASTEL_API_URL` | Backend API URL | `http://localhost:3001` | `http://pastel-api:3001` |
|
||||
| `NODE_ENV` | Node environment | `production` | `production` |
|
||||
| `PORT` | Server port | `3000` | `3000` |
|
||||
|
||||
**Important:** These can be changed at runtime without rebuilding the image!
|
||||
|
||||
## Configuration Examples
|
||||
|
||||
### Docker Compose with Custom API
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
services:
|
||||
pastel-ui:
|
||||
image: ghcr.io/valknarness/pastel-ui:latest
|
||||
ports:
|
||||
- "3000:3000"
|
||||
environment:
|
||||
- PASTEL_API_URL=http://my-custom-api:8080
|
||||
```
|
||||
|
||||
### Docker Compose with External API
|
||||
|
||||
```yaml
|
||||
services:
|
||||
pastel-ui:
|
||||
image: ghcr.io/valknarness/pastel-ui:latest
|
||||
ports:
|
||||
- "3000:3000"
|
||||
environment:
|
||||
- PASTEL_API_URL=https://api.pastel.example.com
|
||||
```
|
||||
|
||||
### Using .env File
|
||||
|
||||
```bash
|
||||
# .env
|
||||
PASTEL_API_URL=http://pastel-api:3001
|
||||
|
||||
# docker-compose.yml will automatically read this
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
## Local Development
|
||||
|
||||
```bash
|
||||
# Install dependencies
|
||||
pnpm install
|
||||
|
||||
# Create .env.local file
|
||||
cat > .env.local << EOF
|
||||
PASTEL_API_URL=http://localhost:3001
|
||||
EOF
|
||||
|
||||
# Start development server
|
||||
pnpm dev
|
||||
|
||||
# Open http://localhost:3000
|
||||
```
|
||||
|
||||
## Building
|
||||
|
||||
```bash
|
||||
# Build the Docker image
|
||||
docker build -t pastel-ui .
|
||||
|
||||
# No build arguments needed - configuration is runtime!
|
||||
```
|
||||
|
||||
## Health Checks
|
||||
|
||||
The container includes health checks using curl:
|
||||
|
||||
```bash
|
||||
# Check container health
|
||||
docker inspect --format='{{.State.Health.Status}}' pastel-ui
|
||||
|
||||
# Manual health check
|
||||
curl http://localhost:3000/
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### API Connection Issues
|
||||
|
||||
**Problem:** Cannot connect to Pastel API
|
||||
|
||||
**Solutions:**
|
||||
|
||||
1. **Check API URL:**
|
||||
```bash
|
||||
docker exec pastel-ui env | grep PASTEL_API_URL
|
||||
```
|
||||
|
||||
2. **Test API connectivity from container:**
|
||||
```bash
|
||||
docker exec pastel-ui curl -f ${PASTEL_API_URL}/api/v1/health
|
||||
```
|
||||
|
||||
3. **Check Docker network:**
|
||||
```bash
|
||||
docker network inspect pastel-network
|
||||
```
|
||||
|
||||
4. **Update API URL without rebuild:**
|
||||
```bash
|
||||
docker-compose down
|
||||
# Edit .env file
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
### CORS Issues
|
||||
|
||||
If you see CORS errors, the API proxy automatically adds CORS headers. Make sure:
|
||||
- The `PASTEL_API_URL` is accessible from the container
|
||||
- The API service is running
|
||||
- Network connectivity exists between containers
|
||||
|
||||
### Container Logs
|
||||
|
||||
```bash
|
||||
# View logs
|
||||
docker-compose logs -f pastel-ui
|
||||
|
||||
# View API proxy logs specifically
|
||||
docker-compose logs -f pastel-ui | grep -i proxy
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
┌──────────────┐
|
||||
│ Browser │
|
||||
└──────┬───────┘
|
||||
│ fetch('/api/pastel/colors/info')
|
||||

|
||||
│ └────────────┬───────────────┘ │
|
||||
└───────────────┼───────────────────┘
|
||||

|
||||
▼
|
||||
┌──────────────────────────────────┐
|
||||
│ Pastel API (port 3001) │
|
||||
│ /api/v1/colors/info │
|
||||
└──────────────────────────────────┘
|
||||
```
|
||||
|
||||
## Benefits of This Approach
|
||||
|
||||
✅ **No Rebuild Required** - Change API URL by restarting container
|
||||
✅ **Environment Flexibility** - Same image works in dev/staging/prod
|
||||
✅ **Network Isolation** - Backend API doesn't need public exposure
|
||||
✅ **CORS Handled** - Proxy adds necessary CORS headers
|
||||
✅ **Type Safety** - TypeScript client works seamlessly with proxy
|
||||
|
||||
## Migration from Old Approach
|
||||
|
||||
If you were using `NEXT_PUBLIC_API_URL` before:
|
||||
|
||||
**Old (Build-time):**
|
||||
```dockerfile
|
||||
ARG NEXT_PUBLIC_API_URL
|
||||
ENV NEXT_PUBLIC_API_URL=${NEXT_PUBLIC_API_URL}
|
||||
RUN pnpm build
|
||||
```
|
||||
|
||||
**New (Runtime):**
|
||||
```dockerfile
|
||||
# No build args needed
|
||||
RUN pnpm build
|
||||
|
||||
# Runtime configuration via environment
|
||||
ENV PASTEL_API_URL=http://localhost:3001
|
||||
```
|
||||
|
||||
The new approach requires a rebuild to switch to the proxy pattern, but after that, no more rebuilds are needed for configuration changes!

## API Integration
|
||||
## WebAssembly Integration
|
||||
|
||||
Pastel UI communicates with the [Pastel API](https://github.com/valknarness/pastel-api) for all color operations. The API client is type-safe and includes automatic retries, caching, and error handling.
|
||||
Pastel UI uses **[@valknarthing/pastel-wasm](https://www.npmjs.com/package/@valknarthing/pastel-wasm)** for all color operations, providing:
|
||||
|
||||
### Example API Usage
|
||||
- **Zero Latency** - All operations run locally in the browser
|
||||
- **Offline First** - Works completely offline after initial load
|
||||
- **No Backend** - No API server required
|
||||
- **132KB Bundle** - Optimized WASM binary
|
||||
- **Type Safe** - Full TypeScript definitions
|
||||
|
||||
### Example Usage
|
||||
|
||||
```typescript
|
||||
import { pastelAPI } from '@/lib/api/client';
|
||||
import { pastelWASM } from '@/lib/api/wasm-client';
|
||||
|
||||
// Get color information
|
||||
const info = await pastelAPI.getColorInfo(['#ff0099']);
|
||||
const info = await pastelWASM.getColorInfo({ colors: ['#ff0099'] });
|
||||
|
||||
// Generate distinct colors
|
||||
const distinct = await pastelAPI.generateDistinct(8, 'ciede2000');
|
||||
const distinct = await pastelWASM.generateDistinct({ count: 8, metric: 'ciede2000' });
|
||||
|
||||
// Create gradient
|
||||
const gradient = await pastelAPI.generateGradient({
|
||||
const gradient = await pastelWASM.generateGradient({
|
||||
stops: ['#ff0000', '#0000ff'],
|
||||
count: 10,
|
||||
colorspace: 'lch'
|
||||
});
|
||||
```
|
||||
|
||||
See [CLAUDE.md](CLAUDE.md) for detailed API integration documentation.

||||
See [CLAUDE.md](CLAUDE.md) for detailed WASM integration documentation.
|
||||
|
||||
## Performance
|
||||
|
||||
Pastel UI is optimized for performance:
|
||||
|
||||
- **Fast Initial Load** - < 200KB initial bundle
|
||||
- **WebAssembly Engine** - Native-speed color operations (132KB WASM)
|
||||
- **Zero Latency** - No network requests for color operations
|
||||
- **Fast Initial Load** - < 350KB total initial bundle
|
||||
- **Code Splitting** - Route-based automatic splitting
|
||||
- **Image Optimization** - Next.js Image with AVIF/WebP
|
||||
- **API Caching** - React Query with smart cache invalidation
|
||||
- **Offline Support** - Works completely offline after first load
|
||||
- **Debounced Updates** - Smooth slider interactions
|
||||
- **Web Workers** - Heavy calculations off main thread

|
||||
#### Cloudflare Pages
|
||||
|
||||

|
||||
# Using docker-compose
|
||||
docker-compose up -d
|
||||
|
||||
# View logs

|
||||
|
||||
```bash
|
||||
# Build the image
|
||||
docker build -t pastel-ui .
|
||||
|
||||

|
||||
```
|
||||
|
||||
#### Available Docker Images
|
||||
|
||||
Images are automatically built and published to GitHub Container Registry:
|
||||
|
||||
- `ghcr.io/valknarness/pastel-ui:latest` - Latest main branch
|
||||
- `ghcr.io/valknarness/pastel-ui:v1.0.0` - Specific version
|
||||
- `ghcr.io/valknarness/pastel-ui:main-abc1234` - Commit SHA
|
||||
|
||||
Supported platforms: `linux/amd64`, `linux/arm64`
|
||||
|
||||
### Static Export
|
||||
#### GitHub Pages
|
||||
|
||||
```bash
|
||||
# Build static export
|
||||
pnpm build
|
||||
|
||||
# Output in out/ directory
|
||||
# Deploy to any static hosting (Netlify, Cloudflare Pages, etc.)
|
||||
# Deploy out/ directory to gh-pages branch
|
||||
```
|
||||
|
||||
#### Self-Hosted (Nginx/Apache)
|
||||
|
||||
```bash
|
||||
# Build static export
|
||||
pnpm build
|
||||
|
||||
# Copy out/ directory to web server
|
||||
cp -r out/* /var/www/html/
|
||||
```
|
||||
|
||||
### Serve Locally
|
||||
|
||||
Test the static build locally:
|
||||
|
||||
```bash
|
||||
# Build
|
||||
pnpm build
|
||||
|
||||
# Serve with any static file server
|
||||
npx serve out
|
||||
# or
|
||||
python -m http.server -d out 8000
|
||||
# or
|
||||
cd out && python3 -m http.server
|
||||
```
|
||||
|
||||
### Docker (Optional)
|
||||
|
||||
For containerized deployment using nginx:
|
||||
|
||||
```bash
|
||||
# Build the image
|
||||
docker build -t pastel-ui .
|
||||
|
||||
# Run container (serves on port 80)
|
||||
docker run -p 80:80 pastel-ui
|
||||
|
||||
# Or use docker-compose
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
The Docker image uses nginx to serve the static files (final image size: ~25MB).
|
||||
|
||||
**Note**: Docker is optional - the app is fully static and can be served by any HTTP server.
