# nx-ui

> nx-ui is the Nexus ReGen shared UI component library: the full shadcn component suite built on Base UI primitives (`@base-ui/react`), restyled to the Untitled UI design language with Nexus ReGen branding. It ships as a shadcn registry — components, AI Elements ports, blocks, domain widgets, reference datasets, themes and lib modules are vendored into consumer repos with the shadcn CLI; nothing imports nx-ui at runtime. A showcase app at ui.nexusregen.com doubles as browsable docs and visual QA.

## Consumption

Add an `@nx-ui` entry to the `registries` map in the consumer's `components.json`. Two hosts serve the same registry JSON — the committed `public/r/` output, one file per item:

```json
{
  "registries": {
    "@nx-ui": {
      "url": "https://raw.githubusercontent.com/nexus-regen/nx-ui/main/public/r/{name}.json",
      "headers": {
        "Authorization": "token ${NX_UI_GITHUB_TOKEN}"
      }
    }
  }
}
```

Or, once deployed, the plain Vercel host with no auth header: `https://ui.nexusregen.com/r/{name}.json`.

Install any item with the shadcn CLI:

```
bunx shadcn@latest add @nx-ui/<name>
```

**Install `@nx-ui/theme` first, always.** It ships the Untitled UI design-token foundation (`styles/nx-ui-theme.css`) that every other item's styling assumes, and it is not an implicit dependency of anything else — nothing pulls it in automatically. Brand variants (`@nx-ui/theme-<name>`) layer on top of it afterwards and are opt-in.

## Version & updates

Registry digest: `sha256:4c4df05706d3c5712121dfdd873622c5249587fc68620f2f02bbacba9eeace3a` — changes whenever any item's content changes. Per-item content hashes live at [versions.json](https://raw.githubusercontent.com/nexus-regen/nx-ui/main/public/r/versions.json) (also at https://ui.nexusregen.com/r/versions.json); record the hashes you installed at in an `nx-ui.lock` via the `@nx-ui/nx-ui-doctor` item and compare later to detect drift. What changed and when is in the [changelog](https://ui.nexusregen.com/changelog) ([machine-readable](https://ui.nexusregen.com/llms-changelog.txt)). Updates are pull-based and explicit: preview with `bunx shadcn@latest add @nx-ui/<name> --diff`, apply with `--overwrite` (keep vendored files pristine — customise via wrapper components).
