Product Mockup Generator API

Hey there! 👋 This is your one-stop solution for creating stunning product mockups with automatic pattern tiling. Perfect for server-to-server communication, web applications, and automated mockup generation through a powerful REST API!

🚀 What You Get

Multiple Products: Curtains, mobile covers, curtains, mugs, and hoodies
Smart Tiling: Automatic pattern tiling across entire surfaces
REST API: Generate mockups via HTTP requests from any application
No File Storage: Images returned directly in responses
API-Only Server: Perfect for server-to-server communication
Cross-Platform: Works on Windows (WSL2), Linux, and macOS

📦 Quick Setup

Step 1: Install Dependencies

Use NVM for managing Node.js versions (recommended), then install ImageMagick:

# Linux (Ubuntu/WSL2) — run these inside your Linux shell (e.g., Ubuntu on WSL2)

# 1) System update
sudo apt update && sudo apt upgrade -y

# 2) Install NVM (Node Version Manager)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

# 3) Load NVM into your current shell
#    Choose the line that matches your shell; you can add it to your shell RC file.
export NVM_DIR="$HOME/.nvm"
# bash
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"
# zsh
# [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
# [ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"

# 4) Install and use the latest LTS Node.js
nvm install --lts
nvm use --lts

# 5) Verify versions
node -v
npm -v

# 6) Install ImageMagick
sudo apt install -y imagemagick

WSL2 Notes:

Open “Ubuntu” (or your chosen distro) and run all commands there, not in Windows PowerShell.
Your project path under WSL usually looks like /home/<user>/mockup-main (avoid working inside /mnt/c/... for better performance).
If you hit ImageMagick policy limits on very large images, consider reducing image sizes or adjusting policy.xml (advanced), or run with smaller useTiling/useDynamic settings.

Step 2: Setup Project

For Local Environment (WSL2):

cd /home/anya/mockup-main

For Online/Server Environment:

cd mockup

npm install

Step 3: Generate Required Maps

bash ./src/create_maps.sh

Step 4: Start the API Server

For Production:

npm start

For Development (with auto-restart):

npm run dev

That's it! Your server is now running on http://localhost:5002 🎉

Development Mode Features:

Auto-restart: Server automatically restarts when you make changes
File watching: Monitors all JavaScript files for changes
Hot reload: No need to manually stop/start the server
Verbose logging: Shows detailed restart information

🎯 Perfect for API Integration

Server-to-Server Communication

Perfect for web applications, mobile apps, automated systems, or any application that needs to generate mockups programmatically.

Generate Single Product Mockup

curl -X POST \
  -F "artwork=@swatches/art1.jpg" \
  http://localhost:5002/api/mockup/generate/tshirt \
  --output tshirt_mockup.jpg

Generate All Products

curl -X POST \
  -F "artwork=@swatches/art1.jpg" \
  http://localhost:5002/api/mockup/generate \
  -o all_mockups.json

Using Postman

Method: POST
URL: http://localhost:5002/api/mockup/generate/tshirt
Body: form-data
Key: artwork (File type)
Value: Select your image file

Command Line (For Testing)

For quick testing or batch processing.

node create_mockup.js --product=tshirt --artwork=swatches/art1.jpg
node create_mockup.js --product=mobile_cover --artwork=swatches/art2.jpg

🔧 API Endpoints

Health & Status

GET /health - Server health check
GET /api/mockup/products - List available products
GET /api/mockup/products/:product/status - Check product status

Mockup Generation

POST /api/mockup/generate/:product - Generate single product mockup
POST /api/mockup/generate - Generate all products
POST /api/mockup/generate-base64/:product - Generate from base64 image
POST /api/mockup/create-product-and-generate - Upload template+mask once, auto-generate maps, then apply a pattern

New: Create Product + Generate (Single-shot)

Endpoint: POST /api/mockup/create-product-and-generate

Purpose: Create or reuse a product under base_images/<foldername>, generate maps (if not already present), and immediately return a mockup using your uploaded pattern image.
Body: multipart/form-data
- foldername (Text): product key, e.g. custom_cover (allowed: a–z, 0–9, _, -)
- template (File): template image → saved as base_images/<foldername>/template.jpg
- mask (File): mask image → saved as base_images/<foldername>/mask.png
- pattern-image (File): pattern/artwork used to render the mockup
- Optional flags (Text):
  - useTiling: true | false (default: true)
  - useDynamic: true | false (default: false)

Behavior:

If base_images/<foldername> exists AND maps/<foldername> has all required maps, the endpoint skips re-copying base images and skips re-generating maps.
Always applies the provided pattern-image to produce and return the mockup.
Cleans uploads/ after each request (preserves .gitkeep).

Response:

Content-Type: image/jpeg
Headers:
- X-Product: <foldername>
- X-Maps-Generated: true if maps were created in this request, otherwise false
- X-Options: {"useDynamic":boolean,"useTiling":boolean}

Postman (form-data):

Method: POST
URL: http://localhost:5002/api/mockup/create-product-and-generate
Body → form-data:
- foldername → Text → custom_cover
- useTiling → Text → false (optional)
- useDynamic → Text → true (optional)
- template → File → select template.jpg
- mask → File → select mask.png
- pattern-image → File → select pattern.jpg

curl:

curl -X POST http://localhost:5002/api/mockup/create-product-and-generate \
  -F foldername=custom_cover \
  -F useTiling=false \
  -F useDynamic=true \
  -F template=@/path/to/template.jpg \
  -F mask=@/path/to/mask.png \
  -F pattern-image=@/path/to/pattern.jpg \
  --output custom_cover_mockup.jpg

💻 API Integration Examples

From Another Node.js Server

import fetch from 'node-fetch';
import FormData from 'form-data';

const formData = new FormData();
formData.append('artwork', fs.createReadStream('image.jpg'));

  method: 'POST',
  body: formData
});

const imageBuffer = await response.buffer();
fs.writeFileSync('mockup.jpg', imageBuffer);

From Python Server

import requests

with open('image.jpg', 'rb') as f:
    files = {'artwork': f}
    response = requests.post('http://your-api-server:5002/api/mockup/generate/tshirt', files=files)
    
with open('mockup.jpg', 'wb') as f:
    f.write(response.content)

🚨 Troubleshooting

"Product not ready"

./create_maps.sh tshirt

"ImageMagick not found"

sudo apt install imagemagick

"CORS error"

Add your domain to the CORS configuration in server.js

"File too large"

Images should be under 50MB

💡 Pro Tips

Use high-quality images - Better input = better output
Clean masks work best - Crisp white areas for pattern placement
Try seamless patterns - They tile beautifully
Experiment with sizes - Different products work better with different pattern sizes
Use the API - Perfect for automation and integration

📊 Performance

File Size Limit: 50MB per request
Rate Limit: 100 requests per 15 minutes per IP
Processing Time: 2-5 seconds per mockup
Memory Usage: Images processed in memory only
No File Storage: Clean server with no disk usage
API-Only: No frontend overhead, pure API performance

🛠️ Development

Adding New Products
