@pacepard/ui

Pacepard design system and React UI component library. Framework-agnostic presentation components for Next.js, Vite, and other React applications.

Installation

pnpm add @pacepard/ui

npm install @pacepard/ui

Quick start

import { Button, Card, Input } from '@pacepard/ui';
import '@pacepard/ui/styles.css';

export function Example() {
    return (
        <Card>
            <Input placeholder="Email" />
            <Button>Continue</Button>
        </Card>
    );
}

Theming

Semantic CSS variables power light and dark themes. Initialize theme on the client:

import { initTheme, setTheme } from '@pacepard/ui';

initTheme('system');
setTheme('dark');

Themes: light, dark, system. Components use tokens such as --pacepard-primary and short aliases like --primary.

Development

pnpm install
pnpm storybook
pnpm check
pnpm build-storybook

Storybook

Storybook is the visual development environment:

pnpm storybook

Includes the accessibility addon. Violations are treated as errors (a11y.test: 'error').

Documentation

• Storybook — interactive components, props, a11y
• Mintlify — conceptual docs under docs/ (installation, theming, tokens)

Mintlify content is intended for docs.pacepard.com and does not duplicate every Storybook example.

# Preview Mintlify docs locally (requires Mintlify CLI)
cd docs && npx mintlify dev

Testing

• Unit/component: Vitest + React Testing Library (pnpm test)
• Browser flows: Playwright against Storybook (pnpm build-storybook && pnpm test:e2e)
  • Dialog, Dropdown, Tabs, Form, Toast/Sonner, InputOTP, Checkbox, Switch, Select, Accordion, Chart, Sheet, theme
  • Axe smoke (e2e/a11y.spec.ts) via Storybook’s axe on Button, Form, Dialog, Tabs, Checkbox, Select (serious/critical; color-contrast disabled)
• Visual regression (Chromatic) is optional and not wired until a project token exists

Publishing

Versioning uses Changesets. On merge to master, the release workflow can open a release PR or publish to npm.

pnpm changeset

Package exports

| Import | Purpose | | --- | --- | | @pacepard/ui | Components, utilities, theme helpers | | @pacepard/ui/styles.css | Design tokens and component styles | | @pacepard/ui/tokens | Typed token references | | @pacepard/ui/theme | Theme helpers (initTheme, setTheme) | | @pacepard/ui/<name> | Per-component ESM entry (kebab-case), e.g. @pacepard/ui/button |

ESM-only. Peers: React, React DOM. Optional peers: react-hook-form (Form), react-is (Recharts). Chart tooltips/legends: import ChartTooltip / ChartLegend from @pacepard/ui.

Examples

Local consumer apps under examples/. They depend on the published npm packages (@pacepard/ui / @pacepard/icons), not the workspace sources:

# Vite
cd examples/vite && pnpm install && pnpm build

# Next.js
cd examples/next && pnpm install && pnpm build

Both examples include Sidebar shell, Questionnaire, Form, Toast, Dialog, Table, Chart, and @pacepard/icons.
