# Java SDK

> Official Java SDK for Bunny Storage

The official Java SDK provides a type-safe way to interact with Bunny Storage in your Java applications. Requires Java 8+.

## Installation

Clone the [GitHub repository](https://github.com/BunnyWay/BunnyCDN.Java.Storage) and build from source.

The SDK uses Jackson for JSON parsing. Add Jackson `Core/Databind/Annotations` as dependencies to your project.

## Quickstart

### Connect to your storage zone

```java theme={null}
import BCDNStorageAPI.BCDNStorage;

// Default region (Falkenstein)
BCDNStorage client = new BCDNStorage("your-storage-zone-name", "your-access-key");

// With specific region
BCDNStorage client = new BCDNStorage("your-storage-zone-name", "your-access-key", "ny");
```

**Available regions:**

| Region Code | Location         | City                  |
| ----------- | ---------------- | --------------------- |
| `de`        | Frankfurt, DE    | Falkenstein (default) |
| `uk`        | London, UK       | London                |
| `ny`        | New York, US     | New York              |
| `la`        | Los Angeles, US  | Los Angeles           |
| `sg`        | Singapore, SG    | Singapore             |
| `se`        | Stockholm, SE    | Stockholm             |
| `br`        | Sao Paulo, BR    | Sao Paulo             |
| `jh`        | Johannesburg, ZA | Johannesburg          |
| `syd`       | Sydney, AU       | Sydney                |

### List files

```java theme={null}
import BCDNStorageAPI.BCDNObject;

BCDNObject[] files = client.getStorageObjects("remote/path/");

for (BCDNObject file : files) {
    System.out.println(file.getObjectName() + " - " + file.getLength() + " bytes");
}
```

Returns an array of `BCDNObject` objects.

**BCDNObject properties:**

* `getGUID()` - Unique identifier
* `getObjectName()` - File name
* `getPath()` - Directory path
* `getLength()` - File size in bytes
* `getChecksum()` - File checksum
* `getDateCreated()` - Creation date
* `getLastChanged()` - Last modification date
* `getIsDirectory()` - Whether it's a directory
* `getServerID()` - Storage server ID
* `getUserID()` - BunnyCDN user ID
* `getStorageZoneName()` - Storage zone name
* `getStorageZoneID()` - Storage zone ID
* `getReplicatedZones()` - Replication regions

### Upload a file

```java theme={null}
client.uploadObject("/path/to/local/file.png", "remote/path/file.png");
```

### Upload a folder

```java theme={null}
// Upload entire folder to storage zone root
client.uploadFolder("/path/to/local/folder/", "/");

// Upload to specific remote path
client.uploadFolder("/path/to/local/folder/", "uploads/");
```

<Note>Empty directories will not be uploaded.</Note>

### Download a file

```java theme={null}
client.downloadObject("remote/path/file.png", "/path/to/local/file.png");
```

### Delete files

```java theme={null}
// Delete a file
client.deleteObject("remote/path/file.png");

// Delete a folder
client.deleteObject("remote/path/folder/");
```

<Note>
  Delete operations are irreversible and will succeed regardless of whether the
  file exists.
</Note>

## Examples

### Basic usage

```java theme={null}
import BCDNStorageAPI.BCDNStorage;
import BCDNStorageAPI.BCDNObject;

public class Main {
    public static void main(String[] args) {
        try {
            BCDNStorage client = new BCDNStorage(
                System.getenv("STORAGE_ZONE"),
                System.getenv("STORAGE_ACCESS_KEY"),
                "de"
            );

            // List all files in root
            BCDNObject[] files = client.getStorageObjects("/");

            for (BCDNObject file : files) {
                if (file.getIsDirectory()) {
                    System.out.println("Folder: " + file.getObjectName());
                } else {
                    System.out.println("File: " + file.getObjectName());
                }
                System.out.println("- Size: " + file.getLength() + " bytes");
                System.out.println("- Last Modified: " + file.getLastChanged());
                System.out.println();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
```

### Upload and download

            BCDNStorage client = new BCDNStorage(
                "my-storage-zone",
                "my-access-key",
                "de"
            );

            // Upload entire assets folder
            client.uploadFolder("./assets/", "static/assets/");
            System.out.println("Folder uploaded successfully!");

        } catch (Exception e) {

@Service
public class BunnyStorageService {

    private final BCDNStorage client;

    public BunnyStorageService(
        @Value("${bunny.storage.zone}") String storageZone,
        @Value("${bunny.storage.access-key}") String accessKey,
        @Value("${bunny.storage.region:de}") String region
    ) {
        this.client = new BCDNStorage(storageZone, accessKey, region);
