How to organize folders in Supabase storage?

 

Step 1: Initial Setup and Setup Supabase Project

 

To organize folders in Supabase Storage, you first need to set up a Supabase project.

npx create-next-app@latest supabase-folder-demo
cd supabase-folder-demo
npm install @supabase/supabase-js

 

Step 2: Initialize Supabase

 

You'll need to initialize your Supabase client in your application. Create a file named supabaseClient.js in the root directory of your project.

import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'https://your-project-ref.supabase.co';
const supabaseAnonKey = 'your-anon-key';

export const supabase = createClient(supabaseUrl, supabaseAnonKey);

Replace 'https://your-project-ref.supabase.co' and 'your-anon-key' with your Supabase project's URL and Anon Key, which you can find in the Supabase dashboard under "Project Settings" > "API".

 

Step 3: Create a Bucket

 

Next, navigate to your Supabase dashboard, go to Storage, and create a new bucket to store your data.

 

Step 4: Organize your Storage Folders

 

To organize folders within a Supabase storage bucket, you'll need to structure them properly. Here's how you can create and manage folders programmatically using the Supabase Storage API:

async function organizeFolderStructure() {
  try {
    // Create a folder named 'images'
    await supabase.storage.from('your-bucket-name').upload('images/dummy.txt', new File([''], 'dummy.txt'));

    // Create a sub-folder named '2023'
    await supabase.storage.from('your-bucket-name').upload('images/2023/dummy.txt', new File([''], 'dummy.txt'));

    // Create another sub-folder named 'thumbnails'
    await supabase.storage.from('your-bucket-name').upload('images/2023/thumbnails/dummy.txt', new File([''], 'dummy.txt'));

    console.log("Folders organized successfully!");
  } catch (error) {
    console.error("Error organizing folders:", error);
  }
}

organizeFolderStructure();

The above code helps you create images/, images/2023/, and images/2023/thumbnails/ folders. Note that Supabase requires a file within each directory upon creation, so a dummy file is uploaded to achieve this.

 

Step 5: List Files and Directories

 

To verify that your folders are correctly organized, use the list functionality provided by Supabase Storage API.

async function listFiles() {
  const { data, error } = await supabase.storage.from('your-bucket-name').list('images/2023/');
  
  if (error) {
    console.error('Error listing files:', error);
  } else {
    console.log('Files in 2023 folder:', data);
  }
}

listFiles();

This function will list all the files and folders within the images/2023/ directory. Adjust the path as needed for your use case.

 

Conclusion

 

By following these steps, you can effectively organize your folders within Supabase Storage, making it easier to manage and access your data. Ensure that you have the correct authentication and read/write permissions set up in your Supabase project to execute these operations.
