# Ascender MinIO SDK

## Overview

The **Ascender MinIO SDK** is a storage service built for the **Ascender Framework**, supporting **Amazon S3 and other S3-compatible storage providers**. It integrates smoothly with **Dependency Injection (DI)** and simplifies common object storage tasks like:
- **Uploading, downloading, and deleting files**
- **Managing buckets**
- **Generating pre-signed URLs**
- **Listing objects in a bucket**

## Installation

Create a new ascender framework project or use existing:
```bash
ascender new --name my_project
```

Navigate to the project directory:
```bash
cd my_project
```

To install the SDK with **Poetry**:

```bash
poetry add ascender-minio
```

---

## Usage

### **1. Register MinIO in `appBootstrap`**
In `bootstrap.py`:

```python
from ascender.core.types import IBootstrap
from minio.minio_provider import provideMinio

appBootstrap: IBootstrap = {
    "providers": [
        provideMinio(
            minio_endpoint="http://localhost:9000",
            minio_access_key="your-access-key",
            minio_secret_key="your-secret-key"
        )
    ]
}
```

---

### **2. Inject `MinioService` into a Controller**
In `main_controller.py`:

```python
from ascender.core import Controller, Post, Get
from minio_service import MinioService

@Controller(standalone=False)
class MainController:
    def __init__(self, minio_service: MinioService):
        self.minio = minio_service

    @Post("upload")
    async def upload_file(self, bucket: str, key: str, data: bytes):
        """Upload a file to MinIO."""
        return await self.minio.put_object(
            Bucket=bucket, Key=key, Data=data,
            ContentLength=len(data), ContentType="application/octet-stream"
        )

    @Get("download/{bucket}/{key}")
    async def download_file(self, bucket: str, key: str):
        """Download a file from MinIO."""
        return await self.minio.read_object(Bucket=bucket, Key=key)

    @Get("list/{bucket}")
    async def list_files(self, bucket: str):
        """List all files in a bucket."""
        return await self.minio.list_objects(Bucket=bucket)

    @Get("presigned/{bucket}/{key}")
    async def generate_presigned_url(self, bucket: str, key: str):
        """Generate a pre-signed URL for a file."""
        return await self.minio.generate_presigned_url(Bucket=bucket, Key=key)

    @Post("delete/{bucket}/{key}")
    async def delete_file(self, bucket: str, key: str):
        """Delete a file from MinIO."""
        return await self.minio.remove_object(Bucket=bucket, Key=key)
```

### **3. Example Usage**
#### **Uploading a File**
```http
POST /upload
Content-Type: application/octet-stream

{
    "bucket": "my-bucket",
    "key": "file.txt",
    "data": "SGVsbG8gV29ybGQh"
}
```

#### **Downloading a File**
```http
GET /download/my-bucket/file.txt
```

#### **Listing Files in a Bucket**
```http
GET /list/my-bucket
```

#### **Generating a Pre-signed URL**
```http
GET /presigned/my-bucket/file.txt
```

#### **Deleting a File**
```http
POST /delete/my-bucket/file.txt
``` 

This setup ensures **clean DI-based injection** without exposing the inner workings of `MinioService`.
