Description: Standalone reusable React UI component library for LORUK
Latest version: 1.0.6

# LORUK UI Library

Standalone UI Library foundation for reusable React components.

## Stack

- React 19 + TypeScript + Vite
- Storybook (React-Vite)
- Tailwind CSS v4 + shared design tokens
- ESLint + Prettier
- Vitest + Testing Library
- tsup (ESM + CJS + type declarations)

## Prerequisites

- Node.js 22+
- npm 10+

## Setup and installation

```bash
cd LORUK
npm install
```

## Local development

Run Vite application using the following command:

```bash
npm run dev
```

## Storybook

Run Storybook locally using the following command:

```bash
npm run storybook
```

Build static Storybook:

```bash
npm run build-storybook
```

## Build and quality commands

```bash
npm run lint
npm run test
npm run test:run
npm run build
npm run build:package
npm run pack:check
npm run format
```

## Versioning

Project now uses `standard-version` for semantic versioning, changelog generation and git tags.

```bash
npm run release

# Force explicit bump type
npm run release:patch
npm run release:minor
npm run release:major

# Preview without making changes
npm run release:dry
```

```bash
npm run release:full
```

`npm run build` produces npm-ready artifacts in `dist/`:

- `index.mjs`
- `index.cjs`
- `index.d.ts`
- `tailwind-preset.mjs`
- `tailwind-preset.cjs`
- `tailwind-preset.d.ts`
- `styles.css`

## Documentation

- Coding guidelines: [docs/CODING_GUIDELINES.md](./docs/CODING_GUIDELINES.md)
- Commit message guidelines: [docs/COMMIT_MESSAGES_GUIDELINES.md](./docs/COMMIT_MESSAGES_GUIDELINES.md)
- Project structure: [docs/PROJECT_STRUCTURE.md](./docs/PROJECT_STRUCTURE.md)

## UI component structure

Component folders under `src/components/ui/` should follow this convention:

- `component-name.tsx`: Component implementation (component export only)
- `component-name.variants.ts`: CVA variant definitions
- `constants.ts`: Component constants and default variant/size values
- `component-name.stories.tsx`: Storybook stories
- `component-name.test.tsx`: Unit tests
- `index.ts`: Local barrel exports

Shared variants used across multiple components should be defined in:

- `src/components/ui/variants.const.ts`

## 🛠️ Automation and linters

`Husky` and `lint-staged` are utilized to automate code quality checks. These guards are employed to ensure that every commit and push meets the defined standards before the repository is reached.

### Git hooks summary

| Hook             | Trigger             | Action                                             | Why?                                                          |
| :--------------- | :------------------ | :------------------------------------------------- | :------------------------------------------------------------ |
| **`pre-commit`** | `git commit`        | Runs `ls-lint`, `cspell`, `eslint`, and `prettier` | Ensures code is clean, formatted, and correctly named.        |
| **`commit-msg`** | After message input | Runs `commitlint`                                  | Enforces **conventional commits** for a readable history.     |
| **`pre-push`**   | `git push`          | Validates branch name & runs `npm run build`       | Prevents "breaking the build" on the remote server.           |
| **`post-merge`** | `git pull`          | Checks for `package-lock.json` changes             | Automatically runs `npm install` to keep dependencies synced. |

### Code validation pipeline

When you stage a file and commit, the following tools are triggered in order via `lint-staged`:

1.  **`ls-lint` (file naming):** Ensures file naming follows our convention
    - _Rule:_ All files (UI components, hooks, etc.) must use `kebab-case` (e.g., `alert-dialog.tsx`).
2.  **`cspell` (spell checker):** Scans for typos in code, comments, and strings
    - _Dictionary:_ Project-specific words like `loruk`, `radix`, and `cmdk` are whitelisted in `cspell.json`.
3.  **`ESLint` (logic & standards):** Checks for code smells, unused variables, and React best practices
    - _Fixing:_ Automatically fixes minor issues using `--fix`
4.  **`Prettier` (formatting):** Standardizes code formatting (tabs, semi-colons, line length)

> [!IMPORTANT]
> **If any check fails, the commit is aborted.** You must fix the reported issues (typos, lint errors, or naming) before trying again.

---

### Commit standards

- **Commit format:** The following structure is required for all commit messages: `type(scope): (ticket-id): description`.
  - _Example:_ `feat(ui): lo2-211: add primary button variant`

## Publish to npm
