# ChicoryTV SPA Component Primitives Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Implement issue #80 by recreating the design-system primitive components as typed React components in the SPA and adding a gallery view for visual review across all three themes.

**Architecture:** Components live under `web/src/components/` and are grouped by domain with a barrel export. Visual styling lives in one shared CSS file using existing ChicoryTV design tokens imported by `web/src/designSystem.ts`; gallery composition lives in `App.tsx` and exercises every primitive.

**Tech Stack:** React 19, TypeScript, Vite, Vitest, Testing Library, lucide-react, existing `design-system/styles.css` tokens.

### Task 1: Baseline and Failing Component Tests

**Files:**
- Modify: `web/src/App.test.tsx`

- [ ] **Step 1: Run baseline tests**

Run: `npm test -- --run` from `web/`.

Expected: existing SPA scaffold tests pass before new work.

- [ ] **Step 2: Write failing tests**

Add tests that import the upcoming component barrel, render the gallery, and verify key API behavior:

```tsx
import { Button, Checkbox, Input, ProgressBar, Switch, Tabs, Tooltip } from './components';

it('exports typed primitives with expected interactions', () => {
  const onSwitch = vi.fn();
  const onCheckbox = vi.fn();
  const onTab = vi.fn();

  render(
    <>
      <Button variant="primary" loading>Saving</Button>
      <Switch checked={false} onChange={onSwitch} label="Show disabled" />
      <Checkbox indeterminate onChange={onCheckbox} label="Select all" />
      <Input label="Channel number" value="5.1" error="Already in use" onChange={() => {}} />
      <ProgressBar value={62} showLabel />
      <Tabs value="streaming" onChange={onTab} tabs={[{ value: 'streaming', label: 'Streaming' }]} />
      <Tooltip label="Reset playout"><button type="button">Reset</button></Tooltip>
    </>
  );

  expect(screen.getByRole('button', { name: 'Saving' })).toBeDisabled();
  fireEvent.click(screen.getByRole('switch', { name: 'Show disabled' }));
  expect(onSwitch).toHaveBeenCalledWith(true);
  expect(screen.getByRole('checkbox', { name: 'Select all' })).toHaveAttribute('aria-checked', 'mixed');
  expect(screen.getByText('Already in use')).toBeInTheDocument();
  expect(screen.getByText('62%')).toBeInTheDocument();
  fireEvent.click(screen.getByRole('tab', { name: 'Streaming' }));
  expect(onTab).toHaveBeenCalledWith('streaming');
  fireEvent.mouseEnter(screen.getByText('Reset'));
  expect(screen.getByRole('tooltip')).toHaveTextContent('Reset playout');
});
```

- [ ] **Step 3: Verify red**

Run: `npm test -- --run App.test.tsx` from `web/`.

Expected: failure because `./components` does not exist yet.

### Task 2: Implement Component Library

**Files:**
- Create: `web/src/components/index.ts`
- Create: `web/src/components/components.css`
- Create: `web/src/components/forms.tsx`
- Create: `web/src/components/dataDisplay.tsx`
- Create: `web/src/components/feedback.tsx`
- Create: `web/src/components/navigation.tsx`

- [ ] **Step 1: Implement typed exports**

Implement these exports with props matching `design-system/components/**/*.d.ts`: `Button`, `IconButton`, `Input`, `Select`, `Switch`, `Checkbox`, `Badge`, `StatusDot`, `Tag`, `ChannelLogo`, `Card`, `Stat`, `ProgressBar`, `Toast`, `Tooltip`, `Spinner`, `NavItem`, `NavSection`, `Tabs`.

- [ ] **Step 2: Implement token-driven CSS**

Use `components.css` classes for variants, sizes, focus, hover, disabled, active, live pulse, indeterminate progress, and theme-aware colors through `--ctv-*` and semantic aliases.

- [ ] **Step 3: Verify green**

Run: `npm test -- --run App.test.tsx` from `web/`.

Expected: new component behavior tests pass.

### Task 3: Add Component Gallery

**Files:**
- Modify: `web/src/App.tsx`
- Modify: `web/src/shell.css`
- Modify: `web/src/App.test.tsx`

- [ ] **Step 1: Add failing gallery assertions**

Assert the SPA renders "Component gallery", "Forms", "Data display", "Feedback", and "Navigation", and includes one visible sample of each primitive family.

- [ ] **Step 2: Verify red**

Run: `npm test -- --run App.test.tsx` from `web/`.

Expected: failure because the gallery is not implemented.

- [ ] **Step 3: Implement gallery**

Compose the new primitives in `App.tsx`, matching the specimen cards' sample content and retaining the three-theme switcher.

- [ ] **Step 4: Verify green**

Run: `npm test -- --run App.test.tsx` from `web/`.

Expected: App tests pass.

### Task 4: Final Verification and Issue Completion

**Files:**
- Inspect all changed files with `git diff`.

- [ ] **Step 1: Run verification**

Run from `web/`:

```bash
npm test -- --run
npm run typecheck
npm run build
```

- [ ] **Step 2: Complete done workflow**

Use the `done` skill for issue #80: read the issue, verify acceptance criteria, check docs impact, run `git status`, commit and push if files changed, comment on Gitea, and close the issue if complete.
