PRD: Authentication Flow

Overview

The Authentication Flow task is a crucial component of the MeshHook project's Phase 3: Frontend (SvelteKit) development. MeshHook aims to provide a powerful, webhook-first, deterministic, Postgres-native workflow engine with features like webhook triggers with signature verification and a visual DAG builder. The task focuses on establishing a secure, efficient, and user-friendly authentication process, aligning with MeshHook's core goals of security, reliability, and ease of use.

Objective: Develop and integrate an authentication flow that supports MeshHook's multi-tenant architecture and leverages Supabase for backend services.

Requirements

Functional Requirements

1. Authentication Mechanism: Implement a secure authentication flow using OAuth 2.0 with Supabase as the authentication provider.
2. User Sessions: Manage user sessions to ensure a smooth user experience while maintaining security.
3. Multi-tenancy Support: Ensure the authentication flow supports multi-tenant access control, aligning with MeshHook's RLS security model.
4. Error Handling: Implement robust error handling for the authentication process to guide users through recovery actions on authentication failures.

Non-Functional Requirements

• Performance: Ensure the authentication process completes within 2 seconds to maintain a responsive user experience.
• Reliability: Achieve 99.9% uptime for the authentication service, with comprehensive logging and monitoring for troubleshooting.
• Security: Implement secure storage and handling of authentication tokens, adherence to OWASP security standards, and regular security audits.
• Maintainability: Code should be clean, well-documented, and modular to facilitate future updates or changes to the authentication flow.

Technical Specifications

Architecture Context

The Authentication Flow will integrate with the following MeshHook components:

• Frontend (SvelteKit/SSR/API): The SvelteKit frontend will serve as the user interface for the authentication process.
• Backend (Supabase): Supabase Auth will be utilized to manage user authentication, session management, and user data.

Implementation Approach

1. Research and Planning: Review Supabase Auth documentation and best practices for OAuth 2.0 implementations.
2. Design: Outline the authentication flow, including UI/UX for login, signup, password recovery, and multi-factor authentication (if applicable).
3. Development:
   • Integrate Supabase Auth with the SvelteKit frontend.
   • Implement UI components for authentication, leveraging SvelteKit's reactivity.
   • Configure secure session management.
4. Testing: Write and execute unit tests, integration tests, and E2E tests for the authentication flow.
5. Deployment: Deploy changes in a staging environment for internal testing, followed by production deployment upon approval.
6. Documentation: Update the project documentation to include details of the authentication flow, including setup, configuration, and usage guidelines.

Data Model

No new data model changes required specifically for authentication. Utilize existing user tables and authentication logs in Supabase.

API Endpoints

No new API endpoints required for this task. Utilize Supabase Auth APIs for authentication-related functionalities.

Acceptance Criteria

• OAuth 2.0 authentication flow implemented using Supabase Auth.
• User can sign up, login, log out, and recover passwords securely.
• Session management is secure and provides a seamless user experience.
• Authentication flow supports multi-tenancy, aligning with the project's RLS security model.
• Comprehensive tests (unit, integration, E2E) are written and passing.
• Documentation for the authentication flow is complete and accessible.
• Security audit performed with no critical issues found.

Dependencies

• Access to Supabase project with Auth configured.
• SvelteKit frontend setup.
• Existing user and authentication log schemas in Supabase.

Implementation Notes

Development Guidelines

• Follow the existing coding standards and best practices for SvelteKit and JavaScript.
• Use async/await for asynchronous operations.
• Ensure all user input is validated and sanitized to prevent injection attacks.

Testing Strategy

• Unit Tests: Focus on individual functions and components.
• Integration Tests: Test the integration between the frontend, Supabase Auth, and session management.
• E2E Tests: Simulate real user scenarios covering the entire authentication flow.

Security Considerations

• Implement CSRF protection for the authentication flow.
• Ensure secure transmission of authentication tokens (HTTPS only).
• Store tokens securely using HttpOnly cookies or secure, client-side storage.
• Regularly rotate session tokens and enforce token expiration.

Monitoring & Observability

• Implement logging for authentication attempts, successes, and failures.
• Monitor performance metrics (response times) and error rates for the authentication process.
• Set up alerts for abnormal activities (e.g., repeated failed login attempts).

By following this PRD, MeshHook will have a secure, efficient, and user-friendly authentication flow, enhancing the overall user experience and maintaining the project's high standards for security and reliability.
