Build and Push Docker Images / docker (push) Successful in 48s
Root causes fixed: 1. State only initialized on mount, not on navigation - Added useEffect to restore offset state when navigating to calculator page 2. CheckoutCancel auto-redirected too quickly (100ms) - Removed auto-redirect, user manually clicks Try Again 3. No restoration logic existed - New useEffect watches currentPage and savedState, restores when showOffsetOrder=true Changes: - App.tsx: Added restoration useEffect that triggers when currentPage='calculator' and savedState has offset state - App.tsx: Added console logs for debugging state restoration - CheckoutCancel.tsx: Removed auto-redirect useEffect and useEffect import - CheckoutSuccess.tsx: Already correctly clears state on successful payment (verified) User flow now: 1. Fill calculator → proceeds to offset order (state saved) 2. Click Proceed to Payment → Stripe checkout 3. Click browser back → lands on cancel page 4. Click Try Again → navigates to calculator 5. App detects savedState.showOffsetOrder=true → restores offset order screen with preserved data
Puffin Offset - Carbon Offsetting for Yachts
This application helps users calculate and offset the carbon footprint of yachts through verified carbon offset projects.
Features
- Carbon footprint calculation for yacht trips
- Integration with Wren carbon offset projects
- Responsive UI for mobile and desktop
- Contact forms powered by Formspree
Setup
Local Development
- Install dependencies:
npm install
- Create a
.envfile with your API tokens:
VITE_WREN_API_TOKEN=your-token-here
VITE_FORMSPREE_CONTACT_ID=your-formspree-contact-form-id
VITE_FORMSPREE_OFFSET_ID=your-formspree-offset-form-id
- Run the development server:
npm run dev
Docker Setup
This project can be run in Docker containers using Docker Compose, and is configured to work with an Nginx reverse proxy on the host.
Prerequisites
- Docker
- Docker Compose
- Nginx (on the host system for SSL termination and reverse proxying)
Running with Docker Compose
- Build and start the containers:
docker compose up -d
-
The Docker container will listen on port 3800, which should be reverse-proxied by your host Nginx.
-
Stop the containers:
docker compose down
Nginx Configuration
The project includes two Nginx configuration files:
nginx.conf: Used INSIDE the Docker container to serve the static files on port 3800nginx-host.conf: A reference config for setting up your Nginx on the HOST to reverse proxy to the Docker container
To set up the host Nginx:
- Copy the nginx-host.conf to your Nginx sites directory:
sudo cp nginx-host.conf /etc/nginx/sites-available/puffinoffset.com
sudo ln -s /etc/nginx/sites-available/puffinoffset.com /etc/nginx/sites-enabled/
- Uncomment the SSL certificate lines after you've obtained certificates using Certbot or another SSL provider
- Test and reload Nginx:
sudo nginx -t
sudo systemctl reload nginx
Environment Variables
When using Docker, the environment variables are mounted as a volume from your local .env file. Make sure it contains:
VITE_WREN_API_TOKEN=your-token-here
VITE_FORMSPREE_CONTACT_ID=your-formspree-contact-form-id
VITE_FORMSPREE_OFFSET_ID=your-formspree-offset-form-id
Backend Service (Optional)
The docker-compose file includes a commented section for running the backend script (app.js) in a separate container. To enable it:
- Uncomment the
backendservice indocker-compose.yml - Ensure your
.envfile contains the needed variables - Run
docker compose up -dto start both services

Building for Production
# Without Docker
npm run build
# With Docker
docker compose build
The production build will be available in the dist directory, or served by Nginx in the Docker container.
