Trading Game Design System

A component library and design token system for the Trading Game product. Built on shadcn/ui with a custom Figma-driven token architecture, Tailwind CSS v4, and React 19.

Published as @trading-game/design-system on npm.

Quick Start

Installation

npm install @trading-game/design-system@latest --safe-chain-skip-minimum-package-age

Note: The --safe-chain-skip-minimum-package-age flag bypasses npm's 72-hour safe-chain hold on newly published packages. Required when the latest version was published less than 72 hours ago (common for AI agents and CI pipelines).

1. Add the CSS imports

In your main CSS file (e.g. globals.css), add these three lines in this order:

@import "@trading-game/design-system/styles";
@import "tailwindcss";
@source "../node_modules/@trading-game/design-system/dist";

Why @source? Tailwind v4 skips node_modules by default. Without this line, Tailwind won't generate CSS for the component classes. Adjust the path if your CSS file is not one level below node_modules (e.g. in a monorepo use ../../node_modules/...).

1b. Vite projects — add the Tailwind plugin

If your project uses Vite (e.g. Vite + React), you must add the Tailwind CSS plugin to your Vite config:

npm install @tailwindcss/vite

// vite.config.js
import react from '@vitejs/plugin-react'
import tailwindcss from '@tailwindcss/vite'

export default {
  plugins: [react(), tailwindcss()],
}

Next.js projects do not need this — Next.js uses PostCSS for Tailwind automatically.

2. Add `class="dark"` to your `<html>` tag

The design system defaults to dark mode. Your root layout must include this:

<html class="dark">

Without this class, components will render without the dark theme applied.

3. Fonts (handled automatically)

The styles import loads Barlow (body) and Orbitron (display/headings) from Google Fonts automatically. No additional font setup is needed.

Use font-body for Barlow and font-display for Orbitron in your Tailwind classes.

4. Use components

import { Button, Card, Badge } from "@trading-game/design-system"

export default function App() {
  return (
    <Card>
      <Button variant="primary">Trade Now</Button>
      <Badge>Live</Badge>
    </Card>
  )
}

Peer dependencies

Make sure these are installed in your project:

npm install react react-dom tailwindcss

Requires React 18+ and Tailwind CSS v4+.

Design tokens

All tokens are CSS custom properties, loaded automatically via @trading-game/design-system/styles.

Using opacity with tokens

Opacity on tokens is allowed and encouraged:

✅ bg-primary/20      → cyan at 20% opacity
✅ border-border/50   → border at 50% opacity
✅ ring-primary/10    → ring at 10% opacity

❌ bg-black/50        → NOT a token, use bg-overlay instead

Heading scale (Orbitron · Semibold · tracking 1.5px · uppercase)

| Class | Size | |---|---| | heading-h1 | 72px | | heading-h2 | 64px | | heading-h3 | 48px | | heading-h4 | 40px | | heading-xs | 24px |

AI Agent Setup

Cursor

Copy the included rule file into your project:

mkdir -p .cursor/rules
cp node_modules/@trading-game/design-system/rules/design-system-consuming-project.mdc .cursor/rules/

Claude Code

Add the following to your project's CLAUDE.md:

## Design System

This project uses @trading-game/design-system. Before writing any UI:
1. Check if the component exists in the package — import it, don't re-implement
2. Use only design token classes (bg-background, text-on-prominent, etc.) — no hardcoded hex or raw Tailwind palette colors
3. Do not install lucide-react, tailwindcss, or other bundled dependencies separately
4. If no token exists for a value, ask before using a hardcoded value

See node_modules/@trading-game/design-system/rules/design-system-consuming-project.mdc for full rules.
See node_modules/@trading-game/design-system/README.md for complete token and component reference.

What the rules enforce

Check the package first before writing any custom UI element
Use only design token classes — no hardcoded hex, no raw Tailwind palette colors, no raw var() wrappers like bg-[var(--token)]
Don't re-install bundled dependencies (lucide-react, tailwindcss, etc.)
Ask before proceeding if no token exists for a value needed

Common mistakes

| Wrong | Right | Why | |---|---|---| | bg-gray-900 | bg-background | Raw Tailwind palette — use tokens | | text-white | text-on-prominent | Not a semantic token | | bg-black/50 | bg-overlay | Overlay has its own token | | bg-[#00FFFF] | bg-primary | Hardcoded hex — use token | | bg-[var(--primary)] | bg-primary | Raw CSS var — Tailwind v4 maps tokens directly | | hsl(var(--primary)) | bg-primary | Tailwind v3 syntax — not needed in v4 | | Installing lucide-react | Already bundled | Icons are included in the package |

Do NOT install separately

These are bundled with the package. Installing them separately can cause version conflicts:

lucide-react — icon library
radix-ui — headless primitives
class-variance-authority — variant API
cmdk — command palette
vaul — drawer
sonner — toast
recharts — charts
react-day-picker — calendar
embla-carousel-react — carousel
react-resizable-panels — resizable panels

Updating design tokens

Design tokens are managed in Figma and exported as JSON variables. To update:

Export updated variables from Figma (TailwindCSS.json, Theme.json, Mode.json)
Update the CSS custom properties in app/globals.css and src/styles.css

Tech stack

React 19 + TypeScript
Tailwind CSS v4 — CSS-first configuration
shadcn/ui (New York style) — base component primitives
Radix UI — accessible headless primitives
Figma — source of truth for design tokens
