Implement calculator state persistence and fix checkout navigation
Features:
- Add useCalculatorState hook with localStorage persistence and 1-hour expiry
- State persists through page reloads and Stripe checkout redirects
- Automatically clears state on successful payment (paid/fulfilled status)

Navigation fixes:
- Fix white page issues on checkout success/cancel pages
- Replace <a> links with button handlers for proper state-based routing
- Pass navigation handlers from App.tsx to checkout pages

State persistence integration:
- TripCalculator: Save/restore calculator inputs (fuel, distance, custom)
- MobileCalculator: Full state persistence for mobile app route
- OffsetOrder: Persist offset percentage and portfolio selection
- MobileOffsetOrder: Persist offset percentage for mobile flow

Carbon impact comparisons:
- Add varied carbon impact comparisons with random selection
- Display 3 comparisons in preview mode, 5 in success mode
- Categories: cars, flights, trees, streaming, homes

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

  1. Install dependencies:
npm install
  1. Create a .env file 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
  1. 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

  1. Build and start the containers:
docker compose up -d
  1. The Docker container will listen on port 3800, which should be reverse-proxied by your host Nginx.

  2. Stop the containers:

docker compose down

Nginx Configuration

The project includes two Nginx configuration files:

  1. nginx.conf: Used INSIDE the Docker container to serve the static files on port 3800
  2. nginx-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:

  1. 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/
  1. Uncomment the SSL certificate lines after you've obtained certificates using Certbot or another SSL provider
  2. 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:

  1. Uncomment the backend service in docker-compose.yml
  2. Ensure your .env file contains the needed variables
  3. Run docker compose up -d to 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.
