Supabase select fields from storage file list

Supabase select fields from storage file list

If you are using Supabase, a powerful open-source alternative to Firebase, you might have come across the need to select specific fields from a file list stored in the storage. In this blog post, we will explore how to achieve this using Supabase’s JavaScript client library and TypeScript.

Method 1: Using the Supabase JavaScript client library

The Supabase JavaScript client library provides a convenient way to interact with the Supabase API. To select specific fields from a file list stored in the storage, you can use the select method provided by the storage module.

Here’s an example code snippet:

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

const supabase = createClient('your-supabase-url', 'your-supabase-key');

async function getFileListFields() {
  const { data, error } = await supabase.storage
    .from('your-storage-bucket')
    .select('field1, field2, field3')
    .list();

  if (error) {
    console.error(error);
    return;
  }

  console.log(data);
}

getFileListFields();

In the above code snippet, replace your-supabase-url with your actual Supabase URL and your-supabase-key with your Supabase API key. Also, replace your-storage-bucket with the name of your storage bucket.

Method 2: Using SQL queries

If you prefer to use SQL queries to select specific fields from a file list stored in the storage, you can do so by utilizing the supabase object’s query method.

Here’s an example code snippet:

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

const supabase = createClient('your-supabase-url', 'your-supabase-key');

async function getFileListFields() {
  const { data, error } = await supabase
    .from('your-storage-bucket')
    .storage()
    .query('SELECT field1, field2, field3 FROM your-storage-bucket');

  if (error) {
    console.error(error);
    return;
  }

  console.log(data);
}

getFileListFields();

Similar to the previous method, make sure to replace your-supabase-url with your actual Supabase URL, your-supabase-key with your Supabase API key, and your-storage-bucket with the name of your storage bucket.

By using either of the above methods, you can easily select specific fields from a file list stored in the storage using Supabase. This allows you to retrieve only the data you need, optimizing performance and reducing unnecessary data transfer.

That’s it for this blog post! We hope you found it helpful in solving your problem of selecting fields from a storage file list in Supabase. Happy coding!
