The answer
Map file extensions to icons: const fileIcons = { '.js': '...', '.html': '...' }. Get the extension from the filename: name.substring(name.lastIndexOf('.')). Look up the icon, default to a generic file icon.

How do you show file type icons in a file explorer?
More FAQs in VS Code Sidebar Features to Implement
File type icons (by extension), search files (recursive filter), context menu (right-click with rename/delete/new), active file highlight, and drag and drop for moving files between folders. These make it feel like a real IDE.
Recursively search the tree: function searchFiles(node, query, results) { if (node.name.includes(query)) results.push(node); if (node.children) node.children.forEach(child => searchFiles(child, query, results)); return results; }
Listen for contextmenu event (right-click). preventDefault. Show a menu at the cursor position with options (Rename, Delete, New File). Remove the menu on click elsewhere.
