# Examples Uploading An Image

## ***Uploading to S3***

```js
import S3 from 'aws-s3';

const config = {
    bucketName: 'myBucket',
    dirName: 'photos', /* optional */
    region: 'eu-west-1',
    accessKeyId: 'ANEIFNENI4324N2NIEXAMPLE',
    secretAccessKey: 'cms21uMxçduyUxYjeg20+DEkgDxe6veFosBT7eUgEXAMPLE',
    s3Url: 'https://my-s3-url.com/', /* optional */
}

const S3Client = new S3(config);
/*  Notice that if you don't provide a dirName, the file will be automatically uploaded to the root of your bucket */

/* This is optional */
const newFileName = 'my-awesome-file';

S3Client
    .uploadFile(file, newFileName)
    .then(data => console.log(data))
    .catch(err => console.error(err))

  /**
   * {
   *   Response: {
   *     bucket: "your-bucket-name",
   *     key: "photos/image.jpg",
   *     location: "https://your-bucket.s3.amazonaws.com/photos/image.jpg"
   *   }
   * }
   */
});
```

## ***Deleting an existing file in your bucket***

In this case the file that we want to delete is in the folder 'photos'

```js
import S3 from 'aws-s3';


const config = {
    bucketName: 'myBucket',
    dirName: 'school-documents',
    region: 'eu-west-1',
    accessKeyId: 'ANEIFNENI4324N2NIEXAMPLE',
    secretAccessKey: 'cms21uMxçduyUxYjeg20+DEkgDxe6veFosBT7eUgEXAMPLE',
    s3Url: 'https://my-s3-url.com/', /* optional */
}

const S3Client = new S3(config);

const filename = 'hello-world.pdf';

/* If the file that you want to delete it's in your bucket's root folder, don't provide any dirName in the config object */

//In this case the file that we want to delete is in the folder 'photos' that we referred in the config object as the dirName

S3Client
    .deleteFile(filename)
    .then(response => console.log(response))
    .catch(err => console.error(err))

  /**
   * {
   *   Response: {
   *      ok: true,
          status: 204,
          message: 'File deleted',
          fileName: 'hello-world.pdf'
   *   }
   * }
   */
});
```
