Folder Explorer Tree View Implementation Plan

1. Project Setup

• The project is already a Next.js project.

2. Data Generation

• Create a JSON file (data.json) containing the fake data for the folder structure, subfolder counts, folder sizes, and folder paths.
• The data should be nested to simulate a realistic file system.
• The data should only contain folders.
• Example data structure:

[
  {
    "name": "Root Folder",
    "type": "folder",
    "path": "/",
    "subfolders": 3,
    "size": 1000000, // in bytes
    "children": [
      {
        "name": "Subfolder 1",
        "type": "folder",
        "path": "/Subfolder 1",
        "subfolders": 2,
        "size": 500000,
        "children": [
          {
            "name": "Subfolder 1.1",
            "type": "folder",
            "path": "/Subfolder 1/Subfolder 1.1",
            "subfolders": 0,
            "size": 100000
          },
          {
            "name": "Subfolder 1.2",
            "type": "folder",
            "path": "/Subfolder 1/Subfolder 1.2",
            "subfolders": 0,
            "size": 200000
          }
        ]
      }
    ]
  }
]

3. Component Structure

• Create a Tree component (components/Tree/index.tsx) to render the entire tree view.
• Create a TreeNode component (components/TreeNode/index.tsx) to represent each folder node in the tree.
  • This component will be responsible for rendering the folder name, badges, and progress bar.

4. Badge Implementation

• Within the TreeNode component, implement the subfolder count badge.
• Use a distinct, visually contrasting color for the badge.
• Display the badge next to the folder name.

5. Progress Bar Implementation

• Implement the storage space progress bar within the TreeNode component.
• Calculate the percentage of storage space occupied by the folder and its contents relative to the root folder's total storage capacity.
• Use a visually appealing progress bar style.

6. Responsiveness and Styling

• Use CSS Modules (components/TreeNode/style.css, components/Tree/style.css) to style the components.
• Ensure the interface is responsive and visually appealing on different screen sizes.

7. Interactivity

• Add interactivity to the tree view, such as expanding and collapsing folder nodes on click.
• Use state management (e.g., useState) to track the expanded/collapsed state of each node.

8. Performance Optimization

• Optimize the tree view for performance, especially when dealing with a large number of folders.
• Consider techniques like virtualization or lazy loading if necessary.

9. Integration

• Integrate the Tree component into the main app/page.tsx file.
• Pass the data from data.json to the Tree component.
