The AwsS3Multipart plugin can be used to upload files directly to an S3 bucket
using S3’s Multipart upload strategy. With this strategy, files are chopped up
in parts of 5MB+ each, so they can be uploaded concurrently. It’s also reliable:
if a single part fails to upload, only that 5MB has to be retried.

Uppy is being developed by the folks at [Transloadit](https://transloadit.com),
a versatile file encoding service.

## Example

```js
import Uppy from '@uppy/core'
import AwsS3Multipart from '@uppy/aws-s3-multipart'

const uppy = new Uppy()
uppy.use(AwsS3Multipart, {
  limit: 2,
  companionUrl: 'https://companion.myapp.com/',
})
```

## Installation

```bash
$ npm install @uppy/aws-s3-multipart
```

Alternatively, you can also use this plugin in a pre-built bundle from
Transloadit’s CDN: Edgly. In that case `Uppy` will attach itself to the global
`window.Uppy` object. See the
[main Uppy documentation](https://uppy.io/docs/#Installation) for instructions.
