```bash
npm install @push.rocks/smartbucket --save
```

This command will add `@push.rocks/smartbucket` to your project's dependencies and install it along with its requirements in the `node_modules` directory.

## Usage

### Introduction

`@push.rocks/smartbucket` provides a robust set of features to manage cloud storage operations in a cloud-agnostic manner. By leveraging this library, you can seamlessly interact with object storage services like AWS S3, without being tied to any vendor-specific implementations. This library not only abstracts basic file operations but also integrates advanced capabilities such as metadata management, data streaming, file locking, and bucket policies, all through a simplified API.

### Setting Up

Begin by importing the necessary classes from the `@push.rocks/smartbucket` package into your TypeScript file. Create an instance of `SmartBucket` with your storage configuration:

```typescript
import {
  SmartBucket,
  Bucket,
  Directory,
  File
} from '@push.rocks/smartbucket';

const mySmartBucket = new SmartBucket({
  accessKey: "yourAccessKey",
  accessSecret: "yourSecretKey",
  endpoint: "yourEndpointURL",
  port: 443,
  useSsl: true
});
```

Replace `"yourAccessKey"`, `"yourSecretKey"`, and `"yourEndpointURL"` with actual data specific to your cloud provider.

### Working with Buckets

#### Creating a New Bucket

Creating a bucket involves invoking the `createBucket` method. Note that bucket names are unique and follow the rules of the cloud provider:

```typescript
async function createBucket(bucketName: string) {
  try {
    const newBucket: Bucket = await mySmartBucket.createBucket(bucketName);
    console.log(`Bucket ${bucketName} created successfully.`);
  } catch (error) {
    console.error("Error creating bucket:", error);
  }
}

createBucket("myNewBucket");
```

#### Listing Buckets

While the library uses cloud-provider capabilities like AWS SDK to list existing buckets, `smartbucket` is aimed at simplifying content management within them.

#### Deleting Buckets

To delete a bucket, simply call the `removeBucket` function:

```typescript
async function deleteBucket(bucketName: string) {
  try {
    await mySmartBucket.removeBucket(bucketName);
    console.log(`Bucket ${bucketName} deleted successfully.`);
  } catch (error) {
    console.error("Error deleting bucket:", error);
  }
}

deleteBucket("anotherBucketName");
```

### File Operations in Buckets

SmartBucket offers a unified API to execute file-based operations efficiently.

#### Uploading Files

Upload a file using the `fastPut` method, specifying the bucket name, file path, and content:

```typescript
async function uploadFile(bucketName: string, filePath: string, fileContent: Buffer | string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  await bucket.fastPut({ path: filePath, contents: fileContent });
  console.log(`File uploaded to ${filePath}`);
}

uploadFile("myBucket", "example.txt", "This is a sample file content.");
```

#### Downloading Files

Download files using `fastGet`. It retrieves the file content as a buffer:

```typescript
async function downloadFile(bucketName: string, filePath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const content: Buffer = await bucket.fastGet({ path: filePath });
  console.log("Downloaded content:", content.toString());
}

downloadFile("myBucket", "example.txt");
```

#### Streaming Files

For large-scale applications, stream files without loading them fully into memory:

```typescript
async function streamFile(bucketName: string, filePath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const stream = await bucket.fastGetStream({ path: filePath }, "nodestream");
  stream.on('data', chunk => console.log("Chunk:", chunk.toString()));
  stream.on('end', () => console.log("Download completed."));
}

streamFile("myBucket", "largefile.txt");
```

#### Deleting Files

Delete files with precision using `fastRemove`:

```typescript
async function deleteFile(bucketName: string, filePath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  await bucket.fastRemove({ path: filePath });
  console.log(`File ${filePath} deleted.`);
}

deleteFile("myBucket", "example.txt");
```

### Directory Operations

Leverage directory functionalities to better organize and manage files within buckets.

#### Listing Directories and Files

Listing contents showcases a directoryâs structure and file contents:

```typescript
async function listDirectory(bucketName: string, directoryPath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const baseDirectory: Directory = await bucket.getBaseDirectory();
  const targetDirectory = await baseDirectory.getSubDirectoryByName(directoryPath);

  console.log('Directories:');
  (await targetDirectory.listDirectories()).forEach(dir => console.log(dir.name));

  console.log('Files:');
  (await targetDirectory.listFiles()).forEach(file => console.log(file.name));
}

listDirectory("myBucket", "path/to/directory");
```

#### Managing Files in Directories

Additional functionalities allow file management, inclusive of handling sub-directories:

```typescript
async function manageFilesInDirectory(bucketName: string, directoryPath: string, fileName: string, content: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const baseDirectory: Directory = await bucket.getBaseDirectory();
  const directory = await baseDirectory.getSubDirectoryByName(directoryPath) ?? baseDirectory;

  await directory.fastPut({ path: fileName, contents: content });
  console.log(`File ${fileName} created in ${directoryPath}`);

  const fileContent = await directory.fastGet({ path: fileName });
  console.log(`Content of ${fileName}: ${fileContent.toString()}`);
}

manageFilesInDirectory("myBucket", "myDir", "example.txt", "File content here");
```

### Advanced Features

The libraryâs advanced features streamline intricate cloud storage workflows.

#### Bucket Policies

The library offers tools for maintaining consistent bucket policies across storage providers, assisting in defining access roles and permissions.

#### Metadata Management

Easily manage and store metadata by using the `MetaData` utility:

```typescript
async function handleMetadata(bucketName: string, filePath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const meta = await bucket.fastStat({ path: filePath });
  console.log("Metadata:", meta.Metadata);
}

handleMetadata("myBucket", "example.txt");
```

#### File Locking

Prevent accidental writes by locking files:

```typescript
async function lockFile(bucketName: string, filePath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const file: File = await bucket.getBaseDirectory().getFileStrict({ path: filePath });
  await file.lock({ timeoutMillis: 600000 }); // Lock for 10 minutes
  console.log(`File ${filePath} locked.`);
}

lockFile("myBucket", "example.txt");
```

#### Trash Management

SmartBucket enables a safe deletion mode where files can be moved to a recycling bin, allowing for restoration:

```typescript
async function trashAndRestoreFile(bucketName: string, filePath: string) {
  const bucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
  const file: File = await bucket.getBaseDirectory().getFileStrict({ path: filePath });

  // Move the file to trash
  await file.delete({ mode: 'trash' });
  console.log(`File ${filePath} moved to trash.`);

  // Retrieve the file from the trash
  const trashFile = await bucket.getTrash().getTrashedFileByOriginalName({ path: filePath });
  await trashFile.restore();
  console.log(`File ${filePath} restored from trash.`);
}

trashAndRestoreFile("myBucket", "example.txt");
```
