# @lilith/catalog

Metadata catalog and data lineage service

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

## Working on this package

The fastest local loop is via Nx:

```bash
pnpm nx test lilith-catalog
pnpm nx lint lilith-catalog
pnpm nx build lilith-catalog
```

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
```
