# walkies

A web-based application for an animal shelter to manage volunteer scheduling, time off, check-in/check-out, and notifications.

## Requirements

- [Go](https://golang.org/) 1.21+
- [Node.js](https://nodejs.org/) 18+
- [Task](https://taskfile.dev/) (`brew install go-task` or see [install docs](https://taskfile.dev/installation/))
- [Docker](https://www.docker.com/) (optional, for containerised deployment)

## Development

Run `task` to list all available tasks.

### Quick start (two terminals)

**Terminal 1 — backend:**
```bash
task web:build    # build frontend once so the Go server has static files
task go:run       # starts API server on :8080
```

**Terminal 2 — frontend dev server:**
```bash
task web:dev      # hot-reload dev server on :3000, proxies /api/v1 → :8080
```

Then open [http://localhost:3000](http://localhost:3000).

### With live backend reload

Install [air](https://github.com/air-verse/air) for hot-reloading the Go server:

```bash
go install github.com/air-verse/air@latest
task web:build
task dev:backend
```

### Common tasks

| Task | Description |
|------|-------------|
| `task build` | Build frontend and Go binary |
| `task go:test` | Run Go tests |
| `task web:test` | Run frontend tests |
| `task go:lint` | Run `go vet` |
| `task tidy` | Tidy Go modules |
| `task clean` | Remove build artifacts |

## Docker

```bash
task docker:up     # build image and start container
task docker:logs   # tail logs
task docker:down   # stop
```

## Configuration

The server is configured via environment variables:

| Variable | Default | Description |
|----------|---------|-------------|
| `PORT` | `8080` | HTTP listen port |
| `DATABASE_DSN` | `walkies.db` | SQLite file path |
| `JWT_SECRET` | `change-me-in-production` | HMAC signing key — **change this** |
| `STATIC_DIR` | `./web/build` | Path to compiled React app |

Copy `.env.example` to `.env` to set these locally (the server reads environment variables directly; use a process manager or Docker to inject them).
