meta: id: podcast-tui-app-53 feature: podcast-tui-app priority: P1 depends_on: [52] tags: [file-based-storage, sync, solidjs]

objective:

• Implement file-based storage for sync
• Store feeds and settings in files
• Implement backup functionality
• Implement restore functionality
• Handle file operations

deliverables:

• src/utils/file-storage.ts with file storage
• src/utils/backup.ts with backup functions
• src/utils/restore.ts with restore functions

steps:

• Create src/utils/file-storage.ts:
  • saveFeedsToFile(feeds: Feed[]): Promise<void>
  • loadFeedsFromFile(): Promise<Feed[]>
  • saveSettingsToFile(settings: Settings): Promise<void>
  • loadSettingsFromFile(): Promise<Settings>
  • Handle file operations and errors
• Create src/utils/backup.ts:
  • createBackup(): Promise<string>
  • backupFeeds(feeds: Feed[]): string
  • backupSettings(settings: Settings): string
  • Include all user data
  • Create backup directory
• Create src/utils/restore.ts:
  • restoreFromBackup(backupData: string): Promise<void>
  • restoreFeeds(backupData: string): void
  • restoreSettings(backupData: string): void
  • Validate backup data

tests:

• Unit: Test file storage functions
• Unit: Test backup functions
• Unit: Test restore functions

acceptance_criteria:

• File storage works correctly
• Backup creates valid files
• Restore loads data correctly
• File operations handle errors

validation:

• Run application and test file storage
• Create backup
• Restore from backup
• Test with different data sizes
• Test error cases

notes:

• Store files in data/ directory
• Use JSON format for storage
• Include version info for compatibility
• Add file encryption option (optional)
• Test with large files
• Handle file permission errors
