useVyre Context

useVyre

AI-native design system for humans and agents. Built on semantic CSS variables — no runtime magic, no hallucinations.

---

Why useVyre?

Most design systems were built for humans reading documentation. useVyre is built for both — every naming convention, token structure, and component API is designed so that AI coding agents (Claude, Cursor, Copilot, Windsurf) can generate correct, consistent UI without guessing.

Problem	useVyre solution
AI hallucinates component props	Every component has an inline AI context block
AI uses raw color values	Semantic tokens replace all raw colors
AI generates inconsistent spacing	4px grid enforced via spacing tokens
AI doesn't know valid variants	data-variant API is explicit and enumerated
Design system only works in one framework	CSS variables work everywhere

Components

40+ production-ready components for React and Vue — buttons, forms (Input, Field, Radio, Checkbox, Select), overlays (Modal, Sheet, Popover, Tooltip), data (DataGrid, Table, Pagination), layout (Sidebar/AppLayout, Card, Tabs), and richer pieces like Kanban, Conversation (chat), DateRangePicker, and a zero-dependency RichTextEditor — plus more on the way.

Every component ships with an inline AI-context block, a machine-readable schema entry, and documented anti-patterns.

Quick Start

# React
npm install @usevyre/tokens @usevyre/react

# Vue 3
npm install @usevyre/tokens @usevyre/vue

// Import once at your app entry point
import "@usevyre/react/styles";   // tokens + component styles (one import)

import { Button, Card, DataGrid } from "@usevyre/react";

Examples

Real, multi-page layouts built entirely from useVyre components:

• Dashboard app — functional 5-page billing dashboard with working sidebar navigation
• Sign-in — auth form with validation

Design Principles

1. Semantic over primitive — --vyre-color-semantic-accent not --amber-400
2. Explicit over implicit — every valid value is documented inline
3. Zero runtime — pure CSS variables, works in any framework
4. AI-first naming — token names describe intent, not appearance
5. Copy-paste friendly — no mandatory build setup, just import CSS and go

Local Development

Run the docs site locally to browse all component examples and live demos.

Prerequisites: Node.js ≥ 18, pnpm ≥ 9

# 1. Clone and install
git clone https://github.com/gapra/usevyre.git
cd usevyre
pnpm install

# 2. Build design tokens (required — components import CSS variables from here)
pnpm --filter @usevyre/tokens build

# 3. Start the docs dev server
pnpm --filter @usevyre/docs dev

Open http://localhost:4321 in your browser.

Shortcut — tokens build + dev server in one command:

pnpm dev:docs
