### Introduction
## Contribution
`@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.
We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)

### Setting Up
[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
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 directorys 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 librarys 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");
```
