React Skills for LlamaFarm Designer

Best practices and patterns for React 18 development in the Designer subsystem.

Tech Stack

  • React 18.2 with StrictMode
  • TypeScript 5.2+ for type safety
  • TanStack Query v5 for server state management
  • React Router v7 for client-side routing
  • TailwindCSS with tailwind-merge and clsx for styling
  • Radix UI primitives for accessible components
  • Vite for build tooling
  • Vitest + React Testing Library for testing

Core Patterns

Component Composition

  • Use composition over inheritance
  • Prefer small, focused components
  • Use forwardRef for components that wrap DOM elements
  • Apply displayName to forwardRef components for DevTools

State Management

  • Local UI state: useState, useReducer
  • Server state: TanStack Query (useQuery, useMutation)
  • Shared UI state: React Context with custom hooks
  • Form state: Controlled components with validation

Hooks

  • Follow Rules of Hooks (top-level, consistent order)
  • Create custom hooks for reusable logic
  • Use query key factories for TanStack Query
  • Memoize expensive computations with useMemo
  • Stabilize callbacks with useCallback

Styling

  • Use cn() from lib/utils to merge Tailwind classes
  • Use cva (class-variance-authority) for component variants
  • Follow dark mode conventions with dark: prefix

Quick Reference

// Utility for merging Tailwind classes
import { cn } from '@/lib/utils'
cn('base-class', condition && 'conditional-class', className)

// Query key factory pattern
export const projectKeys = {
  all: ['projects'] as const,
  lists: () => [...projectKeys.all, 'list'] as const,
  list: (ns: string) => [...projectKeys.lists(), ns] as const,
}

// Context with validation hook
const MyContext = createContext<MyContextType | undefined>(undefined)
export function useMyContext() {
  const ctx = useContext(MyContext)
  if (!ctx) throw new Error('useMyContext must be within MyProvider')
  return ctx
}

Testing

import { renderWithProviders } from '@/test/utils'
import { screen } from '@testing-library/react'

test('renders component', () => {
  renderWithProviders(<MyComponent />)
  expect(screen.getByText('Hello')).toBeInTheDocument()
})
