**Standalone** NestRS app — one crate, logic in `src/`. `GET /`, HTTP only,
no auth, no database. Generated by `nestrs new {{kebab}}`.

## Run

```bash
just dev
just build    # → target/release/{{kebab}}
just run      # build + run in release
```

Open **http://localhost:3000/** in your browser — you should see `Hello World`.

Need several apps sharing product code? Scaffold a
[workspace](/cli/#layout-detection) instead:
`nestrs new <name>`.

## Configuration

Environment variables load from the [`.env` cascade`](https://nestrs.dev/configuration/).
Committed defaults live in `.env` and `.env.development`; copy `.env.example`
to `.env.local` when you add Postgres or Redis later.
