# `storage-js`

JS Client library to interact with Powerbase Storage.

- Documentation: https://powerbase.club/docs/reference/javascript/storage-createbucket

## Quick Start Guide

### Installing the module

```bash
npm install @skorpland/storage-js
```

### Connecting to the storage backend

```js
import { StorageClient } from '@skorpland/storage-js'

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

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

### Handling resources

#### Handling Storage Buckets

- Create a new Storage bucket:

  ```js
  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:

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

- Update a new Storage bucket:

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

- Remove all objects inside a single bucket:

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

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

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

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

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

#### Handling Files

- Upload a file to an existing bucket:

  ```js
  const fileBody = ... // load your file here

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

  > Note:  
  > The path in `data.Key` is prefixed by the bucket ID and is not the value which should be passed to the `download` method in order to fetch the file.  
  > To fetch the file via the `download` method, use `data.path` and `data.bucketId` as follows:
  >
  > ```javascript
  > const { data, error } = await storageClient.from('bucket').upload('/folder/file.txt', fileBody)
  > // check for errors
  > const { data2, error2 } = await storageClient.from(data.bucketId).download(data.path)
  > ```

  > Note: The `upload` method also accepts a map of optional parameters. For a complete list see the [Powerbase API reference](https://powerbase.com/docs/reference/javascript/storage-from-upload).

- Download a file from an exisiting bucket:

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

- List all the files within a bucket:

  ```js
  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 [Powerbase API reference](https://powerbase.com/docs/reference/javascript/storage-from-list).

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

  ```js
  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 [Powerbase API reference](https://powerbase.com/docs/reference/javascript/storage-from-upload).

- Move an existing file:

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

- Delete files within the same bucket:

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

- Create signed URL to download file without requiring permissions:

  ```js
  const expireIn = 60

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

- Retrieve URLs for assets in public buckets:

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