## Usage
`@push.rocks/smartbucket` is a module designed to provide simple cloud-independent object storage functionality. It wraps various cloud storage providers such as AWS S3, Google Cloud Storage, and others, offering a unified API to manage storage buckets and objects within those buckets.

### Listing Buckets
To list all buckets:
Currently, SmartBucket does not include a direct method to list all buckets, but you can access the underlying client provided by the cloud storage SDK to perform such operations, depending on the SDK's capabilities.

#### Streaming Files
SmartBucket allows you to work with file streams, which can be useful for handling large files.
To read a file as a stream:
```typescript
import { ReplaySubject } from '@push.rocks/smartrx';
async function readFileStream(bucketName: string, filePath: string) {
const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
if (myBucket) {
const fileStream: ReplaySubject<Buffer> = await myBucket.fastGetStream({ path: filePath });
fileStream.subscribe({
next(chunk: Buffer) {
console.log("Chunk received:", chunk.toString());
},
complete() {
console.log("File read completed.");
},
error(err) {
console.error("Error reading file stream:", err);
}
});
} else {
console.error(`Bucket ${bucketName} does not exist.`);
}
}
// Use the function
readFileStream("exampleBucket", "path/to/object.txt");
```
To write a file as a stream:
```typescript
import { Readable } from 'stream';
async function writeFileStream(bucketName: string, filePath: string, readableStream: Readable) {
const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
if (myBucket) {
await myBucket.fastPutStream({ path: filePath, dataStream: readableStream });
console.log(`File streamed to ${bucketName} at ${filePath}`);
} else {
console.error(`Bucket ${bucketName} does not exist.`);
}
}
// Create a readable stream from a string
const readable = new Readable();
readable.push('Hello world streamed as a file!');
readable.push(null); // Indicates end of the stream
// Use the function
writeFileStream("exampleBucket", "path/to/streamedObject.txt", readable);
```
### Working with Directories
`@push.rocks/smartbucket` abstracts directories within buckets for easier object management. You can create, list, and delete directories using the `Directory` class.
### Additional Features
```typescript
async function listDirectoryContents(bucketName: string, directoryPath: string) {
const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
if (myBucket) {
const baseDirectory: Directory = await myBucket.getBaseDirectory();
const targetDirectory: Directory = await baseDirectory.getSubDirectoryByName(directoryPath);
console.log('Listing directories:');
const directories = await targetDirectory.listDirectories();
directories.forEach(dir => {
console.log(`- ${dir.name}`);
});
- **Bucket Policies:** Manage bucket policies to control access permissions.
- **Object Metadata:** Retrieve and modify object metadata.
- **Cloud-Agnostic:** Designed to work with multiple cloud providers, allowing for easier migration or multi-cloud strategies.
console.log('Listing files:');
const files = await targetDirectory.listFiles();
files.forEach(file => {
console.log(`- ${file.name}`);
});
} else {
console.error(`Bucket ${bucketName} does not exist.`);
}
}
// Use the function
listDirectoryContents("exampleBucket", "some/directory/path");
```
To create a file within a directory:
```typescript
async function createFileInDirectory(bucketName: string, directoryPath: string, fileName: string, fileContent: string) {
const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
if (myBucket) {
const baseDirectory: Directory = await myBucket.getBaseDirectory();
const targetDirectory: Directory = await baseDirectory.getSubDirectoryByName(directoryPath);
await targetDirectory.createEmptyFile(fileName); // Create an empty file
const file = new File({ directoryRefArg: targetDirectory, fileName });
await file.updateWithContents({ contents: fileContent });
console.log(`File created: ${fileName}`);
} else {
console.error(`Bucket ${bucketName} does not exist.`);
}
}
// Use the function
createFileInDirectory("exampleBucket", "some/directory", "newfile.txt", "Hello, world!");
```
### Advanced Features
#### Bucket Policies
Manage bucket policies to control access permissions. This feature is dependent on the policies provided by the storage service (e.g., AWS S3, MinIO).
#### Object Metadata
You can retrieve and modify object metadata. Metadata can be useful for storing additional information about an object.
To retrieve metadata:
```typescript
async function getObjectMetadata(bucketName: string, filePath: string) {
const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
if (myBucket) {
const metadata = await mySmartBucket.minioClient.statObject(bucketName, filePath);
console.log("Object metadata:", metadata);
} else {
console.error(`Bucket ${bucketName} does not exist.`);
}
}
// Use the function
getObjectMetadata("exampleBucket", "path/to/object.txt");
```
To update metadata:
```typescript
async function updateObjectMetadata(bucketName: string, filePath: string, newMetadata: { [key: string]: string }) {
const myBucket: Bucket = await mySmartBucket.getBucketByName(bucketName);
if (myBucket) {
await myBucket.copyObject({
objectKey: filePath,
nativeMetadata: newMetadata,
deleteExistingNativeMetadata: false,
});
console.log(`Metadata updated for ${filePath}`);
} else {
console.error(`Bucket ${bucketName} does not exist.`);
}
}
// Use the function
updateObjectMetadata("exampleBucket", "path/to/object.txt", {
customKey: "customValue"
});
```
#### Cloud Agnostic
`@push.rocks/smartbucket` is designed to work with multiple cloud providers, allowing for easier migration or multi-cloud strategies. This means you can switch from one provider to another with minimal changes to your codebase.
Remember, each cloud provider has specific features and limitations. `@push.rocks/smartbucket` aims to abstract common functionalities, but always refer to the specific cloud provider's documentation for advanced features or limitations.
> **Note:** This document focuses on basic operations to get you started with `@push.rocks/smartbucket`. For advanced usage, including streaming data, managing bucket policies, and handling large file uploads, refer to the detailed API documentation and examples.
This guide covers the basic to advanced scenarios of using `@push.rocks/smartbucket`. For further details, refer to the API documentation and examples.
