@supabase/storage-js

What is @supabase/storage-js?

@supabase/storage-js is a JavaScript client library for interacting with Supabase Storage. It allows you to manage files and buckets, upload and download files, and handle permissions within the Supabase ecosystem.

What are @supabase/storage-js's main functionalities?

Create a Bucket

This feature allows you to create a new storage bucket in your Supabase project. The code sample demonstrates how to initialize the Supabase client and create a new bucket named 'my-new-bucket'.

const { createClient } = require('@supabase/supabase-js');
const supabase = createClient('https://your-project.supabase.co', 'public-anon-key');

async function createBucket() {
  const { data, error } = await supabase.storage.createBucket('my-new-bucket');
  if (error) console.error('Error creating bucket:', error);
  else console.log('Bucket created:', data);
}

createBucket();

Upload a File

This feature allows you to upload a file to a specified bucket. The code sample demonstrates how to upload a text file named 'hello.txt' to the 'my-new-bucket' bucket.

const { createClient } = require('@supabase/supabase-js');
const supabase = createClient('https://your-project.supabase.co', 'public-anon-key');

async function uploadFile() {
  const file = new File(['Hello World'], 'hello.txt', { type: 'text/plain' });
  const { data, error } = await supabase.storage.from('my-new-bucket').upload('hello.txt', file);
  if (error) console.error('Error uploading file:', error);
  else console.log('File uploaded:', data);
}

uploadFile();

Download a File

This feature allows you to download a file from a specified bucket. The code sample demonstrates how to download a file named 'hello.txt' from the 'my-new-bucket' bucket.

const { createClient } = require('@supabase/supabase-js');
const supabase = createClient('https://your-project.supabase.co', 'public-anon-key');

async function downloadFile() {
  const { data, error } = await supabase.storage.from('my-new-bucket').download('hello.txt');
  if (error) console.error('Error downloading file:', error);
  else console.log('File downloaded:', data);
}

downloadFile();

List Files in a Bucket

This feature allows you to list all files in a specified bucket. The code sample demonstrates how to list all files in the 'my-new-bucket' bucket.

const { createClient } = require('@supabase/supabase-js');
const supabase = createClient('https://your-project.supabase.co', 'public-anon-key');

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

listFiles();

Delete a File

This feature allows you to delete a file from a specified bucket. The code sample demonstrates how to delete a file named 'hello.txt' from the 'my-new-bucket' bucket.

const { createClient } = require('@supabase/supabase-js');
const supabase = createClient('https://your-project.supabase.co', 'public-anon-key');

async function deleteFile() {
  const { data, error } = await supabase.storage.from('my-new-bucket').remove(['hello.txt']);
  if (error) console.error('Error deleting file:', error);
  else console.log('File deleted:', data);
}

deleteFile();

Other packages similar to @supabase/storage-js

aws-sdk

The AWS SDK for JavaScript provides a comprehensive set of tools for interacting with AWS services, including S3 for storage. It offers more extensive features and integrations compared to @supabase/storage-js, but it can be more complex to set up and use.

firebase-admin

The Firebase Admin SDK allows you to manage your Firebase services programmatically. It includes functionality for Firebase Storage, which is similar to Supabase Storage. Firebase offers a broader range of services and integrations, but it may be overkill if you only need storage capabilities.

Quick Start Guide

Installing the module

npm install @supabase/storage-js

Connecting to the storage backend

import { SupabaseStorageClient } from '@supabase/storage-js'

const STORAGE_URL = 'https://<project_ref>.supabase.co/storage/v1'
const SERVICE_KEY = '<service_role>' //! service key, not anon key

const storageClient = new SupabaseStorageClient(STORAGE_URL, {
  apikey: SERVICE_KEY,
  Authorization: `Bearer ${SERVICE_KEY}`,
})

Handling resources

Handling Storage Buckets

• Create a new Storage bucket:

  const { data, error } = await storageClient.createBucket(
    'test_bucket', // Bucket name (must be unique)
    { public: false } // Bucket options
  )
  

• Retrieve the details of an existing Storage bucket:

  const { data, error } = await storageClient.getBucket('test_bucket')
  

• Update a new Storage bucket:

  const { data, error } = await storageClient.updateBucket(
    'test_bucket', // Bucket name
    { public: false } // Bucket options
  )
  

• Remove all objects inside a single bucket:

  const { data, error } = await storageClient.emptyBucket('test_bucket')
  

• Delete an existing bucket (a bucket can't be deleted with existing objects inside it):

  const { data, error } = await storageClient.deleteBucket('test_bucket')
  

• Retrieve the details of all Storage buckets within an existing project:

  const { data, error } = await storageClient.listBuckets()
  

Handling Files

• Upload a file to an existing bucket:

  const fileBody = ... // load your file here
  
  const { data, error } = await storageClient.from('bucket').upload('path/to/file', fileBody)
  

  Note: The upload method also accepts a map of optional parameters. For a complete list see the Supabase API reference.

• Download a file from an exisiting bucket:

  const { data, error } = await storageClient.from('bucket').download('path/to/file')
  

• List all the files within a bucket:

  const { data, error } = await storageClient.from('bucket').list('folder')
  

  Note: The list method also accepts a map of optional parameters. For a complete list see the Supabase API reference.

• Replace an existing file at the specified path with a new one:

  const fileBody = ... // load your file here
  
  const { data, error } = await storageClient
    .from('bucket')
    .update('path/to/file', fileBody)
  

  Note: The upload method also accepts a map of optional parameters. For a complete list see the Supabase API reference.

• Move an existing file:

  const { data, error } = await storageClient
    .from('bucket')
    .move('old/path/to/file', 'new/path/to/file')
  

• Delete files within the same bucket:

  const { data, error } = await storageClient.from('bucket').remove(['path/to/file'])
  

• Create signed URL to download file without requiring permissions:

  const expireIn = 60
  
  const { data, error } = await storageClient
    .from('bucket')
    .createSignedUrl('path/to/file', expireIn)
  

• Retrieve URLs for assets in public buckets:

  const { data, error } = await storageClient.from('public-bucket').getPublicUrl('path/to/file')
