# @lilith/observability-service

Observability Service - SLO definitions, error budgets, and alerting

Backend service. See the `Dockerfile` / `docker-compose.yml` in the repo for
production-like local runs, or use the dev script below for in-process
iteration.

## Scripts

| Command           | Definition                 |
| ----------------- | -------------------------- |
| `pnpm build`      | tsc                        |
| `pnpm start`      | node dist/server.js        |
| `pnpm dev`        | node --watch src/server.js |
| `pnpm test`       | vitest run                 |
| `pnpm test:watch` | vitest                     |

## Layout

## Working on this package

The fastest local loop is via Nx:

```bash
pnpm nx test lilith-observability-service
pnpm nx lint lilith-observability-service
pnpm nx build lilith-observability-service
```

When Nx is unhappy (usually because another worktree has duplicate project
names), bypass it with the underlying tools from this directory:

```bash
npx tsc --noEmit
npx vitest run
```
