Bayan (بيان) — Phase 6 Implementation Summary

This document summarizes the changes and additions made during the implementation of Phase 6: Cloud Persistence.

Overview

Phase 6 introduced database-backed features using Supabase for authenticated users, while strictly preserving the existing editor architecture and maintaining offline/guest functionality.

1. Documents Persistence (Phase 6.1)

Goal: Allow users to save, load, and manage their documents in the cloud.

Files Created:

  • src/js/documents-cloud/documents-api.js (Supabase CRUD operations)
  • src/js/documents-cloud/documents-state.js (In-memory state manager)
  • src/js/documents-cloud/documents-ui.js (DOM interaction and auto-save logic)

UI Additions (src/index.html & src/css/components.css):

  • Sidebar Drawer (#docs-sidebar): A collapsible right-side drawer named "مستنداتي" (My Documents) to list saved documents.
  • Toolbar Additions:
    • A button to toggle the sidebar.
    • A document title indicator (#doc-current-title).
    • A manual save button (#doc-save-btn) that pulses yellow when there are unsaved changes.

Key Behaviors:

  • Auto-save: Automatically triggers every 60 seconds if the document has unsaved changes.
  • Guest Fallback: If a guest user opens the sidebar, they see a prompt to sign in with Google instead of an empty list or errors.

2. Saved Summaries (Phase 6.2)

Goal: Allow users to save their generated summaries and view a history of past summaries.

Files Created:

  • src/js/summaries/summaries-api.js (Supabase CRUD for summaries)
  • src/js/summaries/summaries-ui.js (History panel UI and save logic)

UI Additions:

  • Save Button (#save-summary-btn): Added to the summary card next to the "Copy" button.
  • History Panel (#summary-history-panel): An accordion-style section added to the bottom of the "التلخيص" (Summarize) tab to view past summaries, preview them, and delete them.

3. Settings Sync (Phase 6.3)

Goal: Synchronize user preferences (specifically the UI Theme) across devices.

Files Created:

  • src/js/settings-sync/settings-api.js (Supabase Upsert/Read for user settings)
  • src/js/settings-sync/settings-sync.js (Synchronization orchestrator)

Changes to Existing Code (src/js/theme.js):

  • Modified the setTheme() function to dispatch a custom bayan:themechange event.

Key Behaviors:

  • Debounced Saves: When the theme is changed, it waits 1.5 seconds before syncing to Supabase to prevent spamming the database if the user clicks rapidly.
  • Auto-Load: Upon login, the app fetches the user's saved theme from the database and automatically applies it, overriding the local device default.

HTML Integration (src/index.html)

All the new modules were wired into the main application:

  1. Script tags were added to the <head> section.
  2. The DOMContentLoaded event was updated to initialize the new cloud modules (initSettingsSync(), initDocumentsCloud(), initSummaries()).
  3. The DOM structure was updated surgically via PowerShell scripts to insert the new UI elements cleanly without disrupting the existing flexbox layouts.

Architectural Constraints Maintained

  • src/js/renderer.js and src/js/selection.js remain completely untouched.
  • The core editor loop (User Types → getEditorText() → /api/analyze → render() → setEditorHTML() → restoreSelection()) was not modified.
  • Cloud persistence APIs only interact with the editor via the safe, established boundary methods (getEditorText() and loadDocumentText()).
