Requirements Document

Introduction

This document outlines the requirements for building a Terminal User Interface (TUI) for the Shopify Price Updater script. The TUI will provide an interactive, menu-driven interface that allows users to configure settings, execute operations, schedule price updates, and monitor progress without needing to use command-line arguments or edit environment files directly. The interface will make the tool more accessible to non-technical users while maintaining all existing functionality.

Requirements

Requirement 1

User Story: As a store owner, I want a visual terminal interface to interact with the price updater, so that I can easily access all features without memorizing command-line options.

Acceptance Criteria

1. WHEN the TUI is launched THEN the system SHALL display a main menu with clearly labeled options
2. WHEN a user navigates the interface THEN the system SHALL provide keyboard shortcuts and arrow key navigation
3. WHEN a user selects an option THEN the system SHALL provide immediate visual feedback
4. WHEN the interface is displayed THEN the system SHALL show the current configuration status

Requirement 2

User Story: As a user, I want to configure all environment variables through the TUI, so that I don't need to manually edit .env files.

Acceptance Criteria

1. WHEN a user selects configuration settings THEN the system SHALL display all current environment variables
2. WHEN a user modifies a setting THEN the system SHALL validate the input before saving
3. WHEN configuration is saved THEN the system SHALL update the .env file automatically
4. WHEN invalid configuration is entered THEN the system SHALL display clear error messages
5. WHEN configuration is complete THEN the system SHALL test the Shopify API connection

Requirement 3

User Story: As a user, I want to execute price update operations from the TUI, so that I can run operations with visual progress feedback.

Acceptance Criteria

1. WHEN a user selects price update THEN the system SHALL display current configuration summary
2. WHEN an operation starts THEN the system SHALL show real-time progress indicators
3. WHEN products are being processed THEN the system SHALL display current product information
4. WHEN an operation completes THEN the system SHALL show detailed results summary
5. WHEN errors occur THEN the system SHALL display them in a dedicated error panel

Requirement 4

User Story: As a user, I want to execute rollback operations from the TUI, so that I can easily revert price changes with visual confirmation.

Acceptance Criteria

1. WHEN a user selects rollback THEN the system SHALL display eligible products for rollback
2. WHEN rollback starts THEN the system SHALL show progress with rollback-specific indicators
3. WHEN rollback completes THEN the system SHALL display rollback-specific results
4. WHEN no eligible products exist THEN the system SHALL clearly inform the user

Requirement 5

User Story: As a user, I want to schedule price updates through the TUI, so that I can set up automated operations with a visual interface.

Acceptance Criteria

1. WHEN a user selects scheduling THEN the system SHALL provide date/time picker interface
2. WHEN a schedule is set THEN the system SHALL display countdown timer with cancellation option
3. WHEN scheduled time approaches THEN the system SHALL provide visual and audio notifications
4. WHEN a scheduled operation is cancelled THEN the system SHALL confirm cancellation clearly
5. WHEN scheduling is active THEN the system SHALL prevent conflicting operations

Requirement 6

User Story: As a user, I want to view operation logs and history through the TUI, so that I can review past operations without opening external files.

Acceptance Criteria

1. WHEN a user selects log viewer THEN the system SHALL display recent operation history
2. WHEN logs are displayed THEN the system SHALL provide filtering and search capabilities
3. WHEN log entries are selected THEN the system SHALL show detailed operation information
4. WHEN logs are extensive THEN the system SHALL provide pagination controls
5. WHEN logs are updated THEN the system SHALL refresh the display automatically

Requirement 7

User Story: As a user, I want to debug and analyze product tags through the TUI, so that I can troubleshoot issues without using separate scripts.

Acceptance Criteria

1. WHEN a user selects tag analysis THEN the system SHALL display available product tags
2. WHEN tags are analyzed THEN the system SHALL show product counts per tag
3. WHEN a tag is selected THEN the system SHALL display sample products with that tag
4. WHEN analysis completes THEN the system SHALL provide recommendations for target tags

Requirement 8

User Story: As a user, I want real-time status monitoring in the TUI, so that I can see system health and operation progress at all times.

Acceptance Criteria

1. WHEN the TUI is active THEN the system SHALL display connection status to Shopify API
2. WHEN operations are running THEN the system SHALL show progress bars and completion percentages
3. WHEN errors occur THEN the system SHALL display error indicators in the status bar
4. WHEN system resources are constrained THEN the system SHALL show performance warnings

Requirement 9

User Story: As a user, I want keyboard shortcuts and navigation aids in the TUI, so that I can efficiently operate the interface.

Acceptance Criteria

1. WHEN the interface is displayed THEN the system SHALL show available keyboard shortcuts
2. WHEN a user presses help key THEN the system SHALL display comprehensive help overlay
3. WHEN navigating menus THEN the system SHALL support arrow keys, tab, and enter
4. WHEN in any screen THEN the system SHALL provide consistent back/exit options
5. WHEN shortcuts are used THEN the system SHALL provide immediate response

Requirement 10

User Story: As a user, I want the TUI to handle errors gracefully, so that the interface remains stable and informative during issues.

Acceptance Criteria

1. WHEN API errors occur THEN the system SHALL display user-friendly error messages
2. WHEN network issues happen THEN the system SHALL show retry options and status
3. WHEN configuration errors exist THEN the system SHALL guide users to corrections
4. WHEN unexpected errors occur THEN the system SHALL log details while maintaining interface stability
5. WHEN errors are resolved THEN the system SHALL automatically return to normal operation

Requirement 11

User Story: As a user, I want the TUI to preserve my session and settings, so that I don't lose progress when switching between operations.

Acceptance Criteria

1. WHEN switching between screens THEN the system SHALL maintain current configuration state
2. WHEN operations are interrupted THEN the system SHALL preserve partial progress where possible
3. WHEN returning to previous screens THEN the system SHALL restore previous selections
4. WHEN the TUI is restarted THEN the system SHALL load the last saved configuration
5. WHEN session data exists THEN the system SHALL offer to resume previous operations

Requirement 12

User Story: As a developer, I want the TUI to integrate seamlessly with existing codebase, so that maintenance and updates remain straightforward.

Acceptance Criteria

1. WHEN TUI is implemented THEN the system SHALL reuse existing service classes without modification
2. WHEN TUI operations run THEN the system SHALL generate the same logs as CLI operations
3. WHEN TUI is added THEN the system SHALL maintain backward compatibility with existing CLI interface
