Auth0 React Integration

Add authentication to React single-page applications using @auth0/auth0-react.

Prerequisites

• React 16.11+ application (Vite or Create React App) - supports React 16, 17, 18, and 19
• Auth0 account and application configured
• If you don't have Auth0 set up yet, use the auth0-quickstart skill first

When NOT to Use

• Next.js applications - Use auth0-nextjs skill for both App Router and Pages Router
• React Native mobile apps - Use auth0-react-native skill for iOS/Android
• Server-side rendered React - Use framework-specific SDK (Next.js, Remix, etc.)
• Embedded login - This SDK uses Auth0 Universal Login (redirect-based)
• Backend API authentication - Use express-openid-connect or JWT validation instead
