# Feature Specification: Port the app to Ruby on Rails
|
||
|
||
**Feature Branch**: `010-port-the-app`
|
||
**Created**: 2025-10-17
|
||
**Status**: Draft
|
||
**Input**: User description: "Port the app to Ruby on Rails, still run it in Docker"
|
||
|
||
## User Scenarios & Testing *(mandatory)*
|
||
|
||
### User Story 1 - Continued Application Functionality (Priority: P1)
|
||
|
||
Users can continue to access and use all existing features of the application without interruption or change in behavior after the port to Ruby on Rails.
|
||
|
||
**Why this priority**: This is the primary goal of the porting effort – to ensure business continuity and user satisfaction by maintaining all current functionalities.
|
||
|
||
**Independent Test**: Can be fully tested by verifying all existing end-to-end user flows and features function correctly.
|
||
|
||
**Acceptance Scenarios**:
|
||
|
||
1. **Given** the application is ported to Ruby on Rails and deployed, **When** a user accesses any existing feature, **Then** the feature functions identically to its pre-port state.
|
||
2. **Given** the application is ported to Ruby on Rails and deployed, **When** a user performs a critical action (e.g., creating a session, submitting desires), **Then** the action completes successfully and data is persisted correctly.
|
||
|
||
### Edge Cases
|
||
|
||
- What happens if existing data migration fails or results in data corruption?
|
||
- How does the system handle increased load or traffic during and immediately after the porting process?
|
||
- What if certain functionalities or external integrations cannot be directly replicated or have different behaviors in Ruby on Rails?
|
||
- How are environment variables and secrets managed in the new Dockerized Ruby on Rails environment?
|
||
|
||
## Requirements *(mandatory)*
|
||
|
||
### Functional Requirements
|
||
|
||
- **FR-001**: The ported application MUST provide all existing functionalities available in the current version.
|
||
**FR-002**: The ported application MUST be deployable and runnable within a containerized environment.
|
||
- **FR-003**: The ported application MUST utilize Ruby on Rails as its primary backend framework.
|
||
- **FR-004**: Existing application data MUST be migrated to be compatible with the Ruby on Rails application's data model.
|
||
- **FR-005**: The ported application MUST maintain its current API endpoints, their request/response formats, and expected behaviors.
|
||
**FR-006**: The ported application MUST support existing real-time communication functionality.
|
||
**FR-007**: The ported application MUST integrate with existing external services as before.
|
||
|
||
### Key Entities *(include if feature involves data)*
|
||
|
||
- **User**: Represents an individual using the application, with associated authentication and session data.
|
||
- **Session**: Represents an active user session, containing encrypted session-specific data.
|
||
- **Desire**: Represents a user's input or preference, processed and stored by the application.
|
||
|
||
## Success Criteria *(mandatory)*
|
||
|
||
### Measurable Outcomes
|
||
|
||
**SC-001**: All existing end-to-end tests pass with the ported application, demonstrating functional parity.
|
||
- **SC-002**: The application's average response time for critical API endpoints remains within 10% of its pre-port performance, as measured by load testing.
|
||
- **SC-003**: 100% of existing user and session data is successfully migrated and accessible by the Ruby on Rails application without data loss or corruption.
|
||
**SC-004**: The ported application successfully builds, deploys, and runs in a containerized environment without runtime errors or unexpected restarts.
|
||
- **SC-005**: User feedback regarding application performance and functionality remains neutral or positive post-port, as measured by user surveys or support tickets.
