# How to use AWS SDK for JavaScript with Stook?

You can use the [**AWS SDK for JavaScript**](https://docs.aws.amazon.com/sdk-for-javascript/) to connect your applications to **Medianova Stook Object Storage**. With the SDK, you can set credentials, create buckets, and upload files directly to Stook.

***

### Prerequisites

* Node.js installed on your system
* AWS SDK for JavaScript installed
* Medianova Stook credentials:
  * **Access Key**
  * **Secret Key**
  * **Endpoint**

***

### Installation

Install the AWS SDK for JavaScript:

```bash
npm install aws-sdk
```

***

### Example: Create Bucket and Upload File

`sample.js`

```javascript
var AWS = require('aws-sdk');

var config = { s3ForcePathStyle: true };
var credentials = new AWS.SharedIniFileCredentials({profile: 'medianova'});
AWS.config.credentials = credentials;
AWS.config.update(config);

var ep = new AWS.Endpoint('*******.mncdn.com');
var s3 = new AWS.S3({endpoint: ep});

var bucketName = 'medianovatest';
var keyName = 'hello_world.txt';

s3.createBucket({Bucket: bucketName}, function() {     
    var params = {Bucket: bucketName, Key: keyName, Body: 'Hello World!'};
    s3.putObject(params, function(err, data) {
        if (err) console.log(err);
        else console.log("Successfully uploaded data to " + bucketName + "/" + keyName);
    });
});
```

***

### Config.json Example

You can configure credentials in `config.json` or under `~/.aws/credentials`.

`config.json`:

```json
{
  "accessKeyId": "your_medianova_access_key",
  "secretAccessKey": "your_medianova_secret_key",
  "region": "us-east-1"
}
```

***

### Running the Script

If credentials are saved under `~/.aws/credentials` with profile `medianova`:

```bash
AWS_PROFILE=medianova node sample.js
```

Expected output:

```
Successfully uploaded data to node-sdk-sample-xxxx/hello_world.txt
```

***

### Troubleshooting / FAQ

* **Error:** Credentials not found
  * **Solution:** Ensure `config.json` or `~/.aws/credentials` contains valid keys.
* **Error:** Bucket already exists
  * **Solution:** Use a unique bucket name.
* **Error:** Connection issues
  * **Solution:** Verify endpoint URL and network connectivity.
