- Building Nuxt 3/4 applications with server-side rendering (Node.js 20 LTS+)
- Need secure session management with encrypted cookies
- Protecting server routes and API endpoints
- Accessing Auth0 Management API or custom APIs
**Don't use this when:**
- Using Nuxt 2 (not supported - use different Auth0 SDK)
- Building pure client-side SPA without server (use @auth0/auth0-vue instead)
- Using non-Auth0 authentication provider
- Static site generation only (SSG) without server runtime
π Tips & Best Practices
| Error | Solution |
|-------|----------|
| "Module not found" | Install @auth0/auth0-nuxt, not @auth0/auth0-vue |
| "Missing domain/clientId/clientSecret" | Check NUXT_AUTH0_ prefix, .env location, runtimeConfig |
| "Redirect URI mismatch" | Match Auth0 Dashboard callback to appBaseUrl + /auth/callback |
| "useAuth0 is not defined" | Use only in server context with H3 event object |
| Cookies too large | Use stateful sessions or reduce scopes |
