🎯 Enhanced Attachment System for Agent Zero Chat Interface - #5

[deciduus]

✅ What's Been Implemented

🏗️ Core Architecture Refactoring

• Centralized Attachment Store: Created Alpine.js store pattern following existing codebase conventions
• Component Extraction: Modularized drag-drop overlay into reusable component system
• Logic Migration: Moved ~70 lines of attachment logic from index.js to centralized store
• State Management: Unified attachment state with proper Alpine.js integration

🖱️ Enhanced User Interactions

• Drag & Drop: Improved file handling with visual feedback and counter-based overlay control
• Clipboard Pasting: Smart image paste detection with GUID-based filename generation
• Modal Viewing: Image modal with zoom controls (−/⌂/+) and clean design
• Duplicate Prevention: Fixed bug where re-adding same attachments would fail silently

🔄 Persistence & Device Sync

• Server-Side URLs: Fixed blob URL issues by implementing persistent /image_get API endpoints
• File Type Detection: Added support for 25+ file types with appropriate icons
• Cross-Device Compatibility: Enhanced API with metadata support and cache headers
• Reload Persistence: Attachments now display correctly after page refresh and in loaded chats

🎨 Unified Visual Design

• Tile System: Created consistent 120x120px tiles for all attachment types
• Dynamic Grid Layout: Responsive 1-5 column grid that adapts to screen size
• Distinct Styling: Images show as previews with badges, files show prominent titles with icons
• Hover Effects: Subtle animations with shadow and lift effects
• Mobile Responsive: 90x90px tiles on mobile with optimized spacing

🛠️ Technical Improvements

• Error Handling: Comprehensive error handling with graceful degradation
• Alpine.js Timing: Defensive programming for Alpine.js initialization issues
• API Enhancement: Extended image_get.py to serve all file types with proper icons
• Performance: Added cache headers and optimized file serving

🚀 What I'm Building Next

📄 Enhanced File Preview System (In Progress)

• PDF Preview: Implementing PDF.js integration for inline document viewing with navigation controls
• Text File Preview: Adding syntax-highlighted code preview for .js, .py, .css, .html, etc.
• Hover Tooltips: Rich metadata tooltips showing file size, type, and preview snippets
• Smart Modal Routing: Automatic modal selection (image modal vs file preview modal) based on file type
• API Expansion: Creating file_preview.py endpoint for text-based file rendering

🎛️ Advanced Tile Interactions (Planned)

• Context Menus: Right-click options for "Open in new tab", "Download", "Remove", "Copy filename"
• Drag Reordering: Drag-and-drop tile reordering within attachment lists
• Bulk Operations: Multi-select with Ctrl+click and Shift+click for batch operations
• Enhanced Responsive: Advanced grid layouts that adapt tile sizing based on content and screen size

Next:

• Professional-grade file preview system
• Advanced user interactions matching modern file managers
• Complete attachment ecosystem for Agent Zero

🔗 Architecture

Built on existing Agent Zero patterns with Alpine.js stores, component system, and API conventions. Maintains backward compatibility while providing modern attachment management capabilities.

@deciduus Hi, I don't think we need to do that much work around the alpine store loading - since the attachmentsStore.js exports the store:

export { store }; 

you don't need to do any of these:

const attachmentStore = window.Alpine && window.Alpine.store('chatAttachments');

instead you can just import the module:

import { store } from "...attachmentsStore.js"

and it works regardless of alpine library loading status, this is how we use it in components and modals.

Also changes in initFw.js seem redundant. If you import the component in index.html via x-component, the store script gets imported, because it's imported in the html file's header section, there's no reason to do it again in initFw and manually call initializer function, every alpine store has init() function that get's called when the store is first used.
