# Momswap Geo Backend

Go backend service for user-owned GeoJSON feature collections with Ed25519 authentication and invitation-based onboarding.

## What is implemented

- Ed25519 challenge-response auth (`/v1/auth/challenge`, `/v1/auth/login`)
- Hybrid invitation onboarding (signed invite payload + inviter lineage)
- User registration with ownership proof (`/v1/auth/register`)
- Per-user collections and Point feature CRUD endpoints
- Static no-build frontend (`web/`) using Vue + Vuetify from CDN
- Reusable TypeScript API client (`libs/geo-api-client`) using `@noble/ed25519`
- Bun tests for the TS client and Go tests for API flows
- Gitea CI workflow running Go and Bun test suites

## Quick start

```bash
go test ./...
go run ./cmd/api
```

Server default: `http://localhost:8080`.

Optional environment variables:

- `ADDR` (default `:8080`)
- `ADMIN_PUBLIC_KEY` (bootstrap initial inviter/admin user)

## Docker Compose

Build and run the backend service:

```bash
docker compose up --build -d
```

Stop the service:

```bash
docker compose down
```

For local development with auto-rebuild on file changes:

```bash
docker compose up --watch
```

## Frontend

Open `web/index.html` through a static server (recommended) or browser file URL.

Example:

```bash
python -m http.server 4173
```

Then visit `http://localhost:4173/web/`.

## API client library

Path: `libs/geo-api-client`

```bash
cd libs/geo-api-client
bun install
bun test
bun run build
```

## CI

Workflow: `.gitea/workflows/ci.yml`

- `go test ./...`
- `bun test` in `libs/geo-api-client`
