Getting Started

Installation

Inside your React project directory, run the following:

pnpm add @supabase-cache-helpers/storage-swr

If your package manager does not install peer dependencies automatically, you will need to install them, too.

pnpm add swr react @supabase/storage-js

Quick Start

Import useFileUrl and provide bucket id and path of the desired storage object. The cache key is automatically created from the passed details. You can pass the SWR- and React Query-native options. To list all files in a directory, import useDirectory. If you need all files in a directory and their urls, import useDirectoryUrls.

import { useFileUrl } from "@supabase-cache-helpers/storage-swr";
 
const client = createClient<Database>(
  process.env.SUPABASE_URL,
  process.env.SUPABASE_ANON_KEY
);
 
function Page() {
  const { data: url } = useFileUrl(
    client.storage.from("public_contact_files"),
    "dirname/file.jpg",
    "public", // supports private and public buckets
    {
      // for public buckets. returns null if file does not exist.
      ensureExistence: true,
      revalidateOnFocus: false,
    }
  );
  return <div>...</div>;
}

To upload file(s), import useUpload. Note that the file queries will be revalidated if the uploaded file is relevant (e.g. if it is uploaded into a directory that is currently queried).

import { useUpload } from "@supabase-cache-helpers/storage-swr";
 
const client = createClient<Database>(
  process.env.SUPABASE_URL,
  process.env.SUPABASE_ANON_KEY
);
 
function Page() {
    const { trigger: upload } = useUpload(
        client.storage.from("private_contact_files"),
        { buildFileName: ({ fileName, path }) => `mydirectory/${path}/${fileName}` }
    );
  return <div>...</div>;
}

Finally, you can remove files and directories with useRemoveDirectory and useRemoveFiles.

import { useRemoveDirectory } from "@supabase-cache-helpers/storage-swr";
 
const client = createClient<Database>(
  process.env.SUPABASE_URL,
  process.env.SUPABASE_ANON_KEY
);
 
function Page() {
  const { trigger: remove } = useRemoveDirectory(
    client.storage.from("private_contact_files")
  );
  return <div>...</div>;
}
