# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

**Free Alberta** is a political campaign and advocacy platform built on the Changemaker Lite framework. It's a self-hosted, Docker-based system for political organizing and constituent engagement in Alberta, featuring campaign tools, interactive maps, and food resource directories.

## Architecture

### Service Structure

This is a Docker Compose monorepo with 28+ services. The four main applications are:

| Service | Port | Stack | Purpose |
|---------|------|-------|---------|
| **influence/** | 3333 | Express.js + NocoDB | Campaign & constituent engagement tool - representative lookup, email advocacy, response walls |
| **map/** | 3000 | Express.js + Leaflet.js | Geographic organizing with walk sheets, QR codes, routing |
| **freealberta-food/** | 3003 | Express.js + PostgreSQL | Food resource directory with scraping from InformAlberta, 211, and PDF sources |
| **freealberta-lander/** | 3020 | Nginx static | Landing page |

### Infrastructure Services

- **NocoDB** (8090): No-code database used by influence and map apps
- **Redis** (6379): Shared caching and sessions
- **PostgreSQL**: Separate instances for Listmonk and Food Resources
- **Listmonk** (9001): Email campaign management
- **n8n** (5678): Workflow automation
- **Code Server** (8888): Browser-based VS Code
- **Gitea** (3030): Self-hosted git
- **MkDocs** (4000 dev / 4001 built): Documentation
- **MailHog** (SMTP 1025, UI 8025): Development email testing

### Monitoring Stack (profile: monitoring)

Prometheus (9090), Grafana (3001), cAdvisor, Node Exporter, Alertmanager, Gotify (8889)

## Common Commands

### Root Level (Docker Infrastructure)

```bash
# Start all core services
docker compose up -d

# Start with monitoring stack
docker compose --profile monitoring up -d

# Initial configuration wizard (creates .env)
./config.sh

# Fix container directory permissions (EACCES errors)
./fix-permissions.sh

# Production deployment with Cloudflare tunnel
./start-production.sh

# View logs for a specific service
docker compose logs -f <service-name>
```

### Influence App (influence/app/)

```bash
npm start           # Production
npm run dev         # Development with nodemon
```

### Map App (map/app/)

```bash
npm start           # Production
npm run dev         # Development with nodemon
```

### Food Resources App (freealberta-food/app/)

```bash
npm start                      # Production
npm run dev                    # Development with nodemon
npm run db:init                # Initialize database schema
npm run scrape                 # Run all scrapers
npm run scrape:informalberta   # Scrape InformAlberta only
npm run scrape:211             # Scrape 211 Alberta only
npm run scrape:pdf             # Parse Edmonton's Food Bank PDF
```

### MkDocs Documentation

```bash
# From mkdocs/ directory
mkdocs serve        # Development server with live reload
mkdocs build        # Build static site
```

## Key Architectural Patterns

### Data Flow

- **Influence & Map apps** use NocoDB as their backend database via REST API
- **Food Resources app** uses direct PostgreSQL connection
- **Representative data** in Influence comes from Represent OpenNorth Canada API with NocoDB caching fallback

### Mapping Stack (100% FOSS)

All mapping uses open-source alternatives to Google Maps:
- **Tiles**: OpenStreetMap
- **Frontend**: Leaflet.js
- **Geocoding**: Nominatim + Photon (with fallback chain)
- **Routing**: OSRM (Open Source Routing Machine)

### Common Backend Patterns

All Express apps use:
- **Helmet.js** for security headers
- **express-rate-limit** for API protection
- **Winston** for logging with daily rotation
- **Compression** middleware
- **CORS** enabled

### Environment Configuration

- Root `.env` file contains all service credentials (generated by `config.sh`)
- Each app has its own `.env` for app-specific settings
- Email testing routes through MailHog in development (SMTP port 1025)

## File Structure Conventions

Each Express app follows this structure:
```
app/
├── controllers/    # Route handlers
├── routes/         # API endpoint definitions
├── middleware/     # Auth, rate limiting, CSRF
├── services/       # External API integrations
├── public/         # Frontend assets (HTML, CSS, JS)
├── utils/          # Logger, helpers
├── server.js       # Entry point
└── package.json
```

## External API Dependencies

- **Represent OpenNorth** (represent.opennorth.ca): Canadian elected representative data
- **Nominatim/Photon**: OpenStreetMap geocoding
- **OSRM**: Open source routing

## Cloudflare Tunnel

Production uses Cloudflare tunnel for HTTPS. Configuration at `configs/cloudflare/tunnel-config.yml`.
