Overview

This PR enhances the todo widget functionality by adding support for server-side storage, allowing todo tasks to be persisted and synced across different devices and browsers.

Changes

Core Functionality

• Added storage-type configuration option for todo widget with two modes:
  • browser (default): Tasks stored in browser's localStorage
  • server: Tasks stored on server in JSON files
• Implemented server-side storage using afero filesystem abstraction
• Added new API endpoints for todo data management:
  • GET /api/widgets/todo/{id} - Retrieve todo data
  • PUT /api/widgets/todo/{id} - Save todo data

Configuration

• Added data-path server configuration option (default: ./data)
• Automatic creation of todos data directory on startup
• Updated server startup log to display configured data path

Code Quality

• Converted Todo() function to async for better data loading
• Improved code structure with loadFromStorage() and saveToStorage() helper functions

Documentation

• Updated docs/configuration.md with:
  • New data-path property in Server section
  • New storage-type property in Todo widget section
  • Docker volume mounting examples for data persistence
  • Usage examples for both storage types

Files Changed

• .gitignore - Added data directory
• go.mod & go.sum - Added afero dependency
• internal/glance/config.go - Added DataPath field
• internal/glance/glance.go - Implemented data path initialization and API routes
• internal/glance/static/js/todo.js - Refactored with storage abstraction
• internal/glance/templates/todo.html - Added storage-type data attribute
• internal/glance/widget-todo.go - Implemented server-side storage logic
• docs/configuration.md - Updated documentation

Testing

• Server-side storage creates data directory automatically
• Browser storage maintains backward compatibility
• API endpoints handle GET/PUT requests correctly
• Multiple todo widgets can use different storage types
• Tasks persist across server restarts (server mode)

Breaking Changes

None. This is a backward-compatible enhancement. Existing todo widgets will continue to use browser storage by default.

Example Configuration

server:
  data-path: ./data  # Optional, defaults to ./data

pages:
  - name: Home
    columns:
      - size: full
        widgets:
          # Browser storage (default, backward compatible)
          - type: todo
            title: My Local Tasks
            
          # Server storage (new feature)
          - type: todo
            title: My Synced Tasks
            storage-type: server
            id: shared-tasks
