Managing nested data structures can be a surprisingly complex task. Whether you're handling user directories, organizing project files, or structuring a product catalog, operating on entire branches of a tree often requires writing clunky, error-prone recursive functions. You have to loop through children, then their children, making multiple API calls and adding significant overhead to your application.
At directories.do, we believe in turning complex operations into simple, declarative commands. Our goal is to let you focus on your application's logic, not on the boilerplate of directory traversal. That's where one of our most powerful features comes into play: recursive operations.
This technical guide will walk you through how a single recursive: true flag in our SDK can help you efficiently list, delete, and modify entire directory trees, transforming your code and supercharging your agentic workflows.
Imagine you need to delete a user's entire data folder, /users/jane.doe, which contains multiple subfolders and files. Without a dedicated recursive function, your logic might look something like this in pseudocode:
function deleteDirectoryManually(path) {
// 1. List items in the current path
const items = api.list(path);
// 2. Loop through each item
for (const item of items) {
if (item.is_directory) {
// 3. If it's a directory, call this function again
deleteDirectoryManually(item.path);
} else {
// 4. If it's a file, delete it
api.delete(item.path);
}
}
// 5. Finally, delete the now-empty parent directory
api.delete(path);
}
This approach is inefficient, making numerous round-trips to the API. It's also fragile. What happens if one of the nested calls fails? You could be left with a partially deleted, corrupted directory structure.
The directories.do SDK abstracts all of this complexity away. By adding a simple boolean flag to your API call, you instruct our platform to handle the entire traversal on the backend, ensuring the operation is fast, efficient, and atomic.
Let's start with a common use case: creating a nested path.
With directories.do, you don't need to check if parent directories exist before creating a child. Simply tell our agent to create them for you.
import { Directories } from '@do-sdk/core';
// Initialize the Directories agent
const directoryService = new Directories();
// Create a new user directory with metadata
const newUserDirectory = await directoryService.create({
path: '/users/jane.doe/documents',
metadata: {
userId: 'user-id-12345',
team: 'engineering',
access: ['read', 'write']
},
// If /users or /users/jane.doe don't exist, they will be created automatically
recursive: true
});
console.log('Successfully created directory:', newUserDirectory.path);
In this example, recursive: true ensures that the entire path /users/jane.doe/documents is created in a single, elegant command.
The real power of recursion shines when you need to manage existing directory trees. Here’s how to apply it for listing, deleting, and modifying data.
Use Case: You need to get a complete inventory of every file and folder within a user's directory for a backup or audit process.
Instead of iterating through each level, you can get a flat list of all nodes in one API call.
// List every item under /users/jane.doe, no matter how deep
const allContents = await directoryService.list({
path: '/users/jane.doe',
recursive: true
});
// The output is a single array of all nested directories and files
console.log(`Found ${allContents.length} items in the directory tree.`);
This is incredibly efficient for building file explorers, search indexes, or running analytical queries against your directory structure.
Use Case: A user closes their account, and you need to permanently remove all their associated data in compliance with privacy regulations.
This is a powerful—and potentially destructive—operation, but essential for proper data hygiene. directories.do makes it a safe, single-step process.
// WARNING: This will permanently delete the directory and all its contents.
console.log('Deleting all data for /users/jane.doe...');
const deleteResult = await directoryService.delete({
path: '/users/jane.doe',
recursive: true
});
if (deleteResult.success) {
console.log('Successfully removed the entire directory tree.');
}
Our platform treats this as an atomic transaction. The operation either succeeds completely or fails, preventing orphaned files or partially-deleted states.
Use Case: You need to archive an entire project by updating the metadata for every file and folder within it.
This is where you can combine the power of recursion with our flexible metadata system. Let's say you want to mark everything under /projects/alpha as archived and read-only.
// Apply metadata changes to an entire directory tree
const updateResult = await directoryService.update({
path: '/projects/alpha',
// This metadata will be applied to /projects/alpha and ALL its children
metadata: {
status: 'archived',
access: ['read']
},
recursive: true
});
console.log('Project successfully archived.');
With one command, you've cascaded a status and permission change down an entire project directory, a task that would have otherwise required complex custom scripting.
Mastering recursive operations is fundamental to unlocking the full potential of any modern file system API or directory management service. With directories.do, it's not just a feature; it's a core principle.
