The GridCN

A Tron: Ares inspired theme system for shadcn/ui. Grid-native components, six Greek-god color schemes, three.js effects, and a copy-paste registry that plugs into the shadcn CLI.

---

What is this

The GridCN turns plain shadcn/ui into a neon, glass-HUD design system modeled after Tron: Ares. It ships 55+ base components, 90+ Tron-flavored components (HUDs, radars, timers, maps, 3D grids), and six themes built on oklch() CSS variables — all installable one-by-one through npx shadcn add.

Nothing is locked behind a package. Every component is raw TSX you own, just like shadcn/ui itself. The site at thegridcn.com is both the showcase and the registry.

Features

• Six themes · Ares, Tron, Clu, Athena, Aphrodite, Poseidon
• 145+ components · base UI + Tron-specific HUD/3D/effects
• shadcn CLI native · install any component with npx shadcn add
• Token export · pnpm tokens:build emits per-theme CSS + JSON under public/tokens/
• Three.js integration · Grid3D, Tunnel, GridFloor, always SSR-safe
• Copy-paste friendly · full source visible in the showcase with one-click copy

Quick start

Three ways to use The GridCN, from lightest touch to full clone.

1. Live preview

Browse every component with live switching across the six themes at thegridcn.com/components. Each card shows the rendered component, its variants, and the source.

2. Copy a single component

1. Open the component at thegridcn.com/components.
2. Switch to any theme to preview the styling.
3. Click the copy button on the source block.
4. Paste into your own components/ directory. Install listed peer deps if any.

3. Install via the registry (recommended)

The site exposes a shadcn-compatible registry. Register the namespace once in your components.json:

{
  "registries": {
    "@thegridcn": "https://thegridcn.com/r/{name}.json"
  }
}

Then install anything by short name:

npx shadcn@latest add @thegridcn/button
npx shadcn@latest add @thegridcn/data-card
npx shadcn@latest add @thegridcn/theme-ares

# or several at once
npx shadcn@latest add @thegridcn/button @thegridcn/hud @thegridcn/radar

See the full walkthrough (namespace vs full URL, theming, tokens, troubleshooting) in docs/install.md.

Theme usage

Wrap your app once, then switch themes anywhere.

// app/layout.tsx
import { ThemeProvider } from "@/components/theme";

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    
      
        {children}
      
    
  );
}

// any client component
"use client";
import { useTheme } from "@/components/theme";

export function Toggle() {
  const { theme, setTheme } = useTheme();
  return (
     setTheme(theme === "ares" ? "tron" : "ares")}>
      {theme}
    
  );
}

Themes are data-theme attributes on ``, so any CSS-variable-based component reacts automatically.

Token export

Run pnpm tokens:build to regenerate public/tokens/:

public/tokens/
  index.json         · manifest of all themes
  tron.css           · copy-paste CSS block
  tron.json          · flat vars object { "--primary": "oklch(...)", ... }
  ares.{css,json}
  clu.{css,json}
  athena.{css,json}
  aphrodite.{css,json}
  poseidon.{css,json}

Drop a CSS file into any project:

/* your-app/app/globals.css */
@import "https://thegridcn.com/tokens/ares.css";

Or import the JSON into your Tailwind config:

// tailwind.config.ts
import ares from "./tokens/ares.json" with { type: "json" };

export default {
  theme: {
    extend: {
      colors: {
        primary: ares.vars["--primary"],
        // ... map the rest
      },
    },
  },
};

Development

pnpm install
pnpm dev          # http://localhost:3000
pnpm build        # production build (runs registry:build first)
pnpm lint         # eslint
pnpm tokens:build # regenerate public/tokens/

Package manager is pnpm. Node 18+.
