import { fastifyS3BucketsPlugin } from 'fastify-s3-buckets';
import { S3Client } from '@aws-sdk/client-s3'

const s3Config = {
    endpoint: 'http://s3.localhost.localstack.cloud:4566',
    region: 'eu-west-1',
    credentials: {
        accessKeyId: 'access',
        secretAccessKey: 'secret',
    },
}
const s3Client = new S3Client(s3Config)

const app = fastify()
app.register(fastifyS3BucketsPlugin, {
    s3Client,
    buckets: [
        { Bucket: 'abc', ACL: 'private' },
        { Bucket: 'def', ACL: 'public-read' },
        { Bucket: 'ghi', ACL: 'private' }
    ],

await app.ready() // missing buckets will be created here

```

Note that if buckets already exist, they will not be recreated.
Existing buckets that are not specified will not be deleted.
