# 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: ```json [ { "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.
