A Blockstore implementation that stores blocks on Amazon S3.

## Example - Quickstart

If the flag `createIfMissing` is not set or is false, then the bucket must be
created prior to using blockstore-s3. Please see the AWS docs for information
on how to configure the S3 instance. A bucket name is required to be set at
the s3 instance level, see the below example.

```js
import { S3 } from '@aws-sdk/client-s3'
import { S3Blockstore } from 'blockstore-s3'

const s3 = new S3({
  region: 'region',
  credentials: {
    accessKeyId: 'myaccesskey',
    secretAccessKey: 'mysecretkey'
  }
})

const store = new S3Blockstore(
  s3,
  'my-bucket',
  { createIfMissing: false }
)
```

## Example

```ts
Using with Helia

See [examples/helia](https://github.com/ipfs/js-stores/tree/main/packages/blockstore-s3/examples/helia)
for a full example of how to use Helia with an S3 backed blockstore.
```

# Install

```console
$ npm i blockstore-s3
```
