Settings & Configuration Specification

Overview

This specification defines the settings and configuration management system that allows users to customize application behavior, manage API credentials, and import/export configuration data.

Requirements

Core Functionality

Settings Management

  • The system MUST persist user settings using localStorage
  • The system MUST provide default values for all settings
  • The system MUST apply settings changes immediately without reload
  • The system MUST provide onChange callbacks for setting updates
  • The system MUST validate settings values before saving
  • The system MUST handle corrupted settings data gracefully

Settings Categories

Editor Settings - The system MUST allow users to configure font family - The system MUST allow users to configure font size - The system MUST apply font changes to the editor immediately - The system MUST provide a list of available font options

AI Settings - The system MUST allow users to enable/disable AI feedback globally - The system MUST allow users to configure API keys for LLM services - The system MUST allow users to select their preferred LLM service - The system MUST allow users to select their preferred model - The system MUST provide model options based on selected service - The system MUST validate API keys before saving - The system MUST mask API keys in the UI for security

Theme Settings - The system MUST allow users to select UI theme (dark/light/auto) - The system MUST apply theme changes immediately - The system MUST detect system preference for auto theme

Settings Interface

  • The system MUST provide a dedicated Settings tab
  • The system MUST organize settings by category
  • The system MUST provide clear labels and descriptions for each setting
  • The system MUST provide appropriate input controls for each setting type
  • The system MUST show current values for all settings
  • The system MUST provide save confirmation for changes

Import/Export

Data Export

  • The system MUST allow users to export settings as JSON
  • The system MUST allow users to export prompts as JSON
  • The system MUST allow users to export history data
  • The system MUST allow users to export all application data
  • The system MUST include version information in export files
  • The system MUST validate data before export
  • The system MUST provide download functionality for export files

Data Import

  • The system MUST allow users to import settings from JSON
  • The system MUST allow users to import prompts from JSON
  • The system MUST allow users to import history data
  • The system MUST validate imported data before applying
  • The system MUST provide preview of import data
  • The system MUST warn users about overwriting existing data
  • The system MUST handle version compatibility for imports

Cloud Provider Integration

  • The system MUST support Google Drive integration for backup
  • The system MUST support Dropbox integration for backup
  • The system MUST support OneDrive integration for backup
  • The system MUST handle OAuth authentication for cloud providers
  • The system MUST allow users to select backup destination
  • The system MUST provide clear feedback for backup operations

Selective Import/Export

  • The system MUST allow users to select which data types to export
  • The system MUST allow users to select which data types to import
  • The system MUST provide clear indication of selected data types
  • The system MUST validate selection before processing

Data Management

Reset Functionality

  • The system MUST provide a "Reset to Defaults" option
  • The system MUST warn users before resetting settings
  • The system MUST allow selective reset by category
  • The system MUST preserve critical data (API keys) on reset

Data Validation

  • The system MUST validate all settings values before saving
  • The system MUST validate JSON structure on import
  • The system MUST validate API key format
  • The system MUST provide clear error messages for invalid data

Storage Management

  • The system MUST provide storage usage information
  • The system MUST warn when approaching storage limits
  • The system MUST provide options to clear stored data
  • The system MUST handle storage quota errors gracefully

Non-Functional Requirements

Performance

  • Settings MUST persist within 50ms of change
  • Settings MUST load within 100ms on application start
  • Export operations MUST complete within 1 second for typical data
  • Import operations MUST complete within 2 seconds for typical data
  • Validation MUST complete within 100ms

Security

  • API keys MUST be stored securely in localStorage
  • API keys MUST be masked in the UI
  • Export files MUST NOT contain sensitive data unless explicitly requested
  • The system MUST validate all imported data to prevent injection attacks

Usability

  • Settings MUST be organized logically
  • Settings MUST have clear labels and descriptions
  • Changes MUST take effect immediately
  • Users MUST be able to preview import data before applying
  • Error messages MUST be clear and actionable

Compatibility

  • Export format MUST be backward compatible
  • Import MUST handle version differences gracefully
  • The system MUST provide migration paths for old formats

Implementation Notes

Component Dependencies

  • SettingsManager: Manages user preferences with localStorage persistence
  • ImportExportManager: Handles data import/export with cloud provider support

Settings Schema

  • Use a structured JSON format for settings storage
  • Include version information for compatibility tracking
  • Use consistent naming conventions for setting keys
  • Provide type definitions for validation

Import/Export Format

{
  "version": "1.0",
  "timestamp": "ISO-8601",
  "settings": { /* user settings */ },
  "prompts": [ /* user prompts */ },
  "history": [ /* call history */ }
}

Cloud Integration

  • Use OAuth 2.0 for cloud provider authentication
  • Handle token refresh automatically
  • Provide clear error messages for authentication failures
  • Allow users to revoke cloud access

Validation Strategy

  • Validate JSON structure before parsing
  • Validate required fields are present
  • Validate data types match expected format
  • Validate API key format for each service
  • Provide specific error messages for validation failures

Testing Considerations

  • Test settings persistence across sessions
  • Test settings validation with invalid data
  • Test import/export with various data sizes
  • Test cloud provider authentication flows
  • Test version compatibility for import/export
  • Test reset functionality with various scenarios
  • Test storage quota handling
  • Test concurrent settings modifications
