# 42-lib-outputs

This example shows a `lib` output for pure reusable helpers and data.

It includes:

- one `lib` attrset with rollout data and render helpers,
- one package that turns those helpers into a runnable report, and
- a check that proves the exported `lib` values can be consumed through the flake output.

Useful commands:

```bash
nix flake show
nix eval .#lib.ownerByService.api --raw
nix build
./result/bin/show-lib-plan
nix flake check
```
