PRD: Project Membership Management

Issue: #142
Milestone: Phase 4: Security
Labels: authentication-authorization, hacktoberfest
Owner: Anthony Ettinger (Profullstack)

Overview

The Project Membership Management feature is a critical component of MeshHook's Phase 4 security enhancements. It is designed to manage user roles and permissions within projects, enabling fine-grained access control and ensuring that users can only access resources and execute operations according to their roles. This feature aligns with MeshHook's goals by enhancing security, ensuring multi-tenant RLS security is robust and adhering to the principle of least privilege.

Objectives

• Introduce role-based access control (RBAC) within projects.
• Enable project administrators to manage user roles and permissions.
• Support the seamless integration of project membership management with existing authentication and authorization mechanisms.

Functional Requirements

1. Role Definition and Assignment:

   • Support predefined roles (e.g., Admin, Editor, Viewer) with customizable permissions.
   • Allow project administrators to assign and revoke roles to users within their projects.

2. Permission Management:

   • Implement permissions that cover all user actions within the platform, including creating workflows, viewing logs, and managing project settings.
   • Permissions should be granular to allow for precise access control.

3. User Interface for Membership Management:

   • Develop UI components that enable project administrators to manage project members' roles easily.
   • Integrate these components with the existing project settings UI.

4. Audit Logging:

   • Record all membership changes (role assignments/revocations) in the audit log.

5. API Support:

   • Provide RESTful API endpoints to programmatically manage project membership.

Non-Functional Requirements

• Performance: Ensure that the project membership management operations do not significantly impact the overall performance of the platform.
• Security: Leverage existing RLS and encryption mechanisms to secure membership data. Ensure all changes go through authentication and authorization checks.
• Maintainability: Follow clean code practices, ensuring new code is modular, well-commented, and easy to understand.

Technical Specifications

Architecture Context

• Supabase Authentication & Authorization: Utilize Supabase's built-in capabilities for user management and integrate custom RBAC for project-level access control.
• SvelteKit: Build the management UI as part of the existing SvelteKit application, ensuring a consistent user experience.

Implementation Approach

1. Design Data Model for Roles & Permissions:

   • Extend the existing schema to include roles, permissions, and a user_project_roles junction table.
   • Update schema.sql with new tables and relationships.

2. API Development:

   • Implement API endpoints for managing roles and permissions (/api/roles, /api/permissions, /api/project-members).

3. UI Development:

   • Design and implement UI components for role and permission management within the project settings page.
   • Ensure the UI is intuitive and accessible to non-technical users.

4. Integration Testing:

   • Conduct thorough testing to ensure new features work seamlessly with existing authentication and authorization flows.

5. Documentation & Training:

   • Update the project documentation to include guides on managing project membership.
   • Prepare training materials for project administrators.

Data Model Changes

• New Tables:
  • roles: Stores role definitions.
  • permissions: Stores permission definitions.
  • user_project_roles: Associates users with roles within projects.

API Endpoints

• POST /api/projects/{projectId}/members: Add a member to a project with a specific role.
• GET /api/projects/{projectId}/members: List project members and their roles.
• PATCH /api/projects/{projectId}/members/{userId}: Update a member's role.
• DELETE /api/projects/{projectId}/members/{userId}: Remove a member from a project.

Acceptance Criteria

• Project administrators can assign, change, and revoke roles to users within their projects.
• Users can perform only those actions permitted by their roles.
• Membership changes are logged in the audit log.
• API endpoints for project membership management are functional and secure.
• UI for managing project membership is intuitive and consistent with the rest of the platform.
• Documentation and training materials are updated and available.

Dependencies

• Supabase for authentication and authorization.
• Existing database schema and API infrastructure.
• Frontend development environment setup with SvelteKit.

Implementation Notes

Development Guidelines

• Use TypeScript for type safety and better code documentation.
• Follow existing patterns for API design and error handling.
• Ensure new UI components are responsive and match the platform's look and feel.

Testing Strategy

• Unit Tests: Write unit tests for all new backend logic and utility functions.
• Integration Tests: Test API endpoints to ensure they correctly interact with the database and other services.
• UI Tests: Use Playwright or a similar tool to test the new UI components and workflows.

Security Considerations

• Ensure all membership management operations require proper authentication and authorization.
• Sanitize inputs to prevent SQL injection and other common web vulnerabilities.
• Use existing RLS policies to secure access to membership data.

Monitoring & Observability

• Monitor API performance and error rates related to project membership management.
• Extend existing logging mechanisms to include membership management operations.

Related Documentation

• Updated schema.sql reflecting the new data model.
• API documentation for the new endpoints (/docs/api).
• User guide for project administrators on managing project membership (/docs/user-guide).

Start with the existing schema.sql, authentication and authorization integration, and project settings UI; then review the proposed /api/projects/{projectId}/members endpoints and related API documentation. Done requires role assignment and enforcement, audit logging, secure API behavior, an intuitive UI, tests, and updated documentation and training materials.
