# `@proj-airi/server`

HTTP and WebSocket backend for AIRI. This app owns auth, billing, chat synchronization, gateway forwarding, and server-side observability export.

## What It Does

- Serves the Hono-based API and WebSocket endpoints.
- Uses Postgres as the source of truth for users, billing, and durable state.
- Uses Redis for cache, KV, Pub/Sub, and Streams.
- Forwards GenAI requests to the configured upstream gateway and records billing from usage.
- Exports traces, metrics, and logs through OpenTelemetry.

## How To Use It

Install dependencies from the repo root and run scoped commands:

```sh
pnpm -F @proj-airi/server typecheck
pnpm -F @proj-airi/server exec vitest run
pnpm -F @proj-airi/server build
```

For local observability infrastructure, use:

```sh
docker compose -f apps/server/docker-compose.otel.yml up -d
```
