# @lossless.zone/objectstorage

> 🚀 S3-compatible object storage server with a slick management UI — powered by [`smartstorage`](https://code.foss.global/push.rocks/smartstorage).

**objectstorage** gives you a fully featured, self-hosted S3-compatible storage server with a beautiful web-based management interface — all in a single Docker image. No Java, no bloat, no fuss.

Built on Deno for the backend and [`@design.estate/dees-catalog`](https://code.foss.global/design.estate/dees-catalog) for a polished UI, it speaks the S3 protocol out of the box while adding powerful management features on top.

## ⚡ Quick Start

### Docker (recommended)

```bash
docker run -d \
  --name objectstorage \
  -p 9000:9000 \
  -p 3000:3000 \
  -v objstdata:/data \
  -e OBJST_ACCESS_KEY=myadminkey \
  -e OBJST_SECRET_KEY=mysupersecret \
  -e OBJST_ADMIN_PASSWORD=myuipassword \
  code.foss.global/lossless.zone/objectstorage:latest
```

Then open **http://localhost:3000** for the management UI and use **http://localhost:9000** as your S3 endpoint.

### Deno (development)

```bash
# Clone and install frontend dependencies
git clone ssh://git@code.foss.global:29419/lossless.zone/objectstorage.git
cd objectstorage
pnpm install
pnpm run build

# Run in ephemeral mode (data stored in .nogit/objstdata)
deno run --allow-all mod.ts server --ephemeral
```

## ⚙️ Configuration

objectstorage is configured through environment variables, CLI flags, or programmatic config. **Environment variables take precedence** over CLI flags.

### Environment Variables

| Variable | Description | Default |
|---|---|---|
| `OBJST_PORT` | Storage API port | `9000` |
| `UI_PORT` | Management UI port | `3000` |
| `OBJST_STORAGE_DIR` | Data storage directory | `/data` |
| `OBJST_ACCESS_KEY` | Access key ID | `admin` |
| `OBJST_SECRET_KEY` | Secret access key | `admin` |
| `OBJST_ADMIN_PASSWORD` | Admin UI password | `admin` |
| `OBJST_REGION` | Storage region identifier | `us-east-1` |

### CLI Flags

```bash
deno run --allow-all mod.ts server [options]

Options:
  --storage-port <port>  Storage API port (default: 9000)
  --ui-port <port>       Management UI port (default: 3000)
  --storage-dir <path>   Storage directory (default: /data)
  --ephemeral            Use ./.nogit/objstdata for storage (dev mode)
```

## 🖥️ Management UI

The web-based management UI is served on the UI port (default: `3000`). Log in with username `admin` and the configured admin password.

### Overview

Dashboard showing server status, uptime, storage usage, bucket count, and connection info.

![Overview](./docs/01-overview.png)

### Buckets

Create/delete buckets. View object counts and sizes. Attach/detach named policies per bucket.

![Buckets](./docs/02-buckets.png)

### Browser

Finder-style column browser for objects. Upload, download, preview, move, rename, and delete files and folders — with syntax-highlighted code preview.

![Browser](./docs/03-browser.png)

Right-click any item for quick actions:

![Context Menu](./docs/11-context-menu.png)

#### Inline Code Editing

Click Edit on any text file to open the built-in Monaco editor with syntax highlighting, language detection, and save-back-to-storage.

![Code Editing](./docs/06-code-editing.png)

#### PDF Viewer

PDF files render inline with a full-featured viewer — page navigation, zoom, fit-to-page, thumbnails, download, and print.

![PDF Viewer](./docs/07-pdf-viewer.png)

### Policies

Create reusable named policies with IAM-style S3 statements. Attach policies to multiple buckets at once.

![Policies](./docs/04-policies.png)

#### Attaching Policies to Buckets

From the Buckets view, click the policy icon on any bucket to see attached and available policies. Attach or detach with one click.

![Attach Policy](./docs/08-attach-policy.png)

### Access Keys

Add and remove access credentials. Secret keys are masked. Changes take effect immediately — no server restart needed.

![Access Keys](./docs/05-access-keys.png)

#### Adding Access Keys

Click "Add Key" to create new access credentials. They're immediately available for API authentication.

![Add Access Key](./docs/09-add-access-key.png)

### Configuration

View your server's current configuration at a glance — ports, region, storage directory, and auth/CORS status.

![Configuration](./docs/06-config.png)

### Dark Theme

Full dark theme support — automatically follows your system preference via `prefers-color-scheme`.

## 📋 Named Policy System

objectstorage adds a **named policy** abstraction on top of standard S3 bucket policies. Instead of editing raw JSON per bucket, you define reusable policy templates and attach them to any number of buckets.

### How it works

1. **Create a named policy** in the Policies view — give it a name, description, and S3 policy statements
2. **Attach it to buckets** — from the Policies view or the Buckets view
3. **objectstorage merges** all attached policy statements into a single S3 policy document and applies it to the bucket automatically

### `${bucket}` placeholder

Use `${bucket}` in your policy's `Resource` ARN and it will be replaced with the actual bucket name when applied:

```json
[
  {
    "Sid": "PublicRead",
    "Effect": "Allow",
    "Principal": "*",
    "Action": "s3:GetObject",
    "Resource": "arn:aws:s3:::${bucket}/*"
  }
]
```

This lets one policy like "Public Read" work across many buckets without hardcoding names.

### Lifecycle

- **Updating a policy** automatically recomputes and re-applies the merged S3 policy on all attached buckets
- **Deleting a policy** detaches it from all buckets and recomputes each
- **Deleting a bucket** cleans up its policy attachments automatically

## 🔌 S3 API Usage

Use any S3-compatible client to interact with the storage. Here are some examples:

### AWS CLI

```bash
# Configure AWS CLI
aws configure set aws_access_key_id admin
aws configure set aws_secret_access_key admin
aws configure set default.region us-east-1

# Create a bucket
aws --endpoint-url http://localhost:9000 s3 mb s3://my-bucket

# Upload a file
aws --endpoint-url http://localhost:9000 s3 cp myfile.txt s3://my-bucket/

# List objects
aws --endpoint-url http://localhost:9000 s3 ls s3://my-bucket/

# Download a file
aws --endpoint-url http://localhost:9000 s3 cp s3://my-bucket/myfile.txt ./downloaded.txt
```

### Node.js / TypeScript (AWS SDK v3)

```typescript
import { S3Client, PutObjectCommand, ListObjectsV2Command } from '@aws-sdk/client-s3';

const s3 = new S3Client({
  endpoint: 'http://localhost:9000',
  region: 'us-east-1',
  credentials: {
    accessKeyId: 'admin',
    secretAccessKey: 'admin',
  },
  forcePathStyle: true,
});

// Upload an object
await s3.send(new PutObjectCommand({
  Bucket: 'my-bucket',
  Key: 'hello.txt',
  Body: 'Hello, S3!',
}));

// List objects in a bucket
const result = await s3.send(new ListObjectsV2Command({
  Bucket: 'my-bucket',
}));
console.log(result.Contents);
```

### Python (boto3)

```python
import boto3

s3 = boto3.client(
    's3',
    endpoint_url='http://localhost:9000',
    aws_access_key_id='admin',
    aws_secret_access_key='admin',
    region_name='us-east-1',
)

# Upload a file
s3.put_object(Bucket='my-bucket', Key='hello.txt', Body=b'Hello from Python!')

# List objects
response = s3.list_objects_v2(Bucket='my-bucket')
for obj in response.get('Contents', []):
    print(obj['Key'], obj['Size'])
```
