• Internationalization support (80+ locales)
• Session management via SessionProvider
• Customizable components through slot overrides
• Storybook setup for component development and documentation

@ory/nuxt - Nuxt 3/4 integration module

• Auto-imported composables: useOryLogin, useOryRegistration, useOryRecovery, useOryVerification, useOrySettings, useOrySession, useOryLogout, useOryFlowError
• Server-side proxy for secure cookie handling

Further comments

The Vue/Nuxt packages follow the same architecture patterns as the React/Next.js implementation:

• Same component hierarchy and naming conventions
• Same context/provider architecture (using Vue's provide/inject)
• Same flow handling logic and state management
• Same theming system structure with customizable components
• Same utility functions and SDK helpers

All authentication methods are supported including password, passwordless (code), social login (OIDC), passkeys, WebAuthn, TOTP, and recovery codes.

This fixes the issue #581
