PRD: Create/Edit Workflow

Issue: #127
Milestone: Phase 3: Frontend (SvelteKit)
Labels: workflow-management, hacktoberfest
Phase: Phase 3
Section: Workflow Management

---

Overview

The "Create/Edit Workflow" feature is a cornerstone of the MeshHook project, enabling users to define and modify their workflow processes visually. This feature leverages MeshHook's core capabilities, such as webhook triggers with signature verification and a visual DAG builder, to provide a user-friendly interface for constructing complex, deterministic workflows. This task aligns with MeshHook's goals of combining the simplicity of visual workflow construction with the robustness of event sourcing and multi-tenant security.

Functional Requirements

1. Visual Workflow Construction:

   • Users must be able to create new workflows using a visual DAG builder.
   • The workflow editor must support editing existing workflows.
   • Users should be able to define webhook triggers, nodes (e.g., transform, http_call, branch, delay, terminate), and connections in the DAG.

2. Workflow Configuration:

   • Support configuration of webhook triggers including signature verification methods.
   • Allow users to configure node settings using JSON Schema-driven forms.
   • Enable versioning control, allowing users to save drafts and publish immutable workflow versions.

3. Integration with Existing Systems:

   • Ensure the workflow creation/editing process integrates smoothly with the backend for persistence.
   • Utilize Supabase Realtime for live updates during workflow configuration.

4. User Experience:

   • Provide a "Test run" feature that allows users to execute the workflow with a sample payload and view the execution path and results.
   • Implement a "resume from step" feature for debugging and testing workflows.

5. Documentation and Best Practices:

   • Document all user-facing features and configurations.
   • Follow MeshHook coding standards and project conventions throughout development.

Non-Functional Requirements

• Performance: The workflow editor must load and respond to user input without perceptible delay, maintaining a responsive user experience.
• Reliability: Changes to workflows must be saved reliably, with appropriate feedback provided to users on success or failure.
• Security: Adhere to MeshHook's security guidelines, especially regarding multi-tenancy and secrets management.
• Maintainability: Code should be clean, well-documented, and easy to maintain, with a clear separation of concerns and modular architecture.

Technical Specifications

Architecture Context

• Utilize SvelteKit for building the frontend workflow editor, ensuring integration with the existing SvelteKit/Svelte 5 based architecture.
• The frontend must communicate with the backend via RESTful APIs or GraphQL for fetching, saving, and publishing workflows.
• Supabase Realtime to be used for providing live feedback and updates in the editor.

Implementation Approach

1. Analysis:

   • Review existing frontend and backend codebases to understand current implementation and integration points.

2. Design:

   • Define the UI/UX for the create/edit workflow interface, focusing on simplicity and usability.
   • Outline the frontend-backend interaction model, including API requests and real-time updates.

3. Implementation:

   • Develop the frontend interface using SvelteKit, incorporating the visual DAG builder and configuration forms.
   • Implement API calls for fetching, saving, and publishing workflows.
   • Integrate real-time feedback for the editing process using Supabase Realtime.

4. Testing:

   • Write unit and integration tests covering new features and interactions.
   • Conduct manual testing to ensure the feature meets user experience expectations.

5. Deployment:

   • Ensure the feature is fully integrated into the CI/CD pipeline for automated testing and deployment.

Data Model

No immediate changes to the existing data model are required for this task. Should adjustments become necessary, they will be documented and included in the project's schema migrations.

API Endpoints

• GET /api/workflows/{id}: Fetch a specific workflow for editing.
• POST /api/workflows: Create a new workflow.
• PUT /api/workflows/{id}: Update an existing workflow.
• POST /api/workflows/{id}/publish: Publish a workflow version.

Acceptance Criteria

• Users can create new workflows using a visual interface.
• Users can edit existing workflows, with changes reflected in real-time.
• Workflows can be saved, with the ability to publish new versions.
• The workflow editor performs reliably under normal usage conditions.
• Security and multi-tenancy guidelines are adhered to throughout the implementation.
• The feature integrates seamlessly with the existing MeshHook architecture and patterns.

Dependencies

• Access to the MeshHook codebase and development environment.
• Supabase project access for real-time updates and backend integration.

Implementation Notes

Development Guidelines

• Follow the existing project structure and coding conventions.
• Utilize TypeScript for type safety and better developer experience.
• Ensure code is well-commented, and document any new functions or modules.

Testing Strategy

• Implement unit tests for new components and utility functions.
• Write integration tests to cover API interactions and real-time behavior.
• Perform manual testing for user experience verification.

Security Considerations

• Ensure all user input is validated both client-side and server-side.
• Use existing project mechanisms for authentication and authorization.
• Follow secure coding practices to prevent common vulnerabilities (e.g., XSS, CSRF).

Monitoring and Observability

• Integrate with existing logging and monitoring solutions to track usage and errors.
• Consider adding performance metrics specific to the workflow editor if necessary.
