Configure the collections object to specify which collections should use the AWS S3 adapter. The slug must match one of your existing collection slugs.
The config object can be any S3ClientConfig object (from @aws-sdk/client-s3). This is highly dependent on your AWS setup. Check the AWS documentation for more information.
When enabled, this package will automatically set disableLocalStorage to true for each collection.
When deploying to Vercel, server uploads are limited with 4.5MB. Set clientUploads to true to do uploads directly on the client. You must allow CORS PUT method for the bucket to your website.
Configure signedDownloads (either globally of per-collection in collections) to use presigned URLs for files downloading. This can improve performance for large files (like videos) while still respecting your access control. Additionally, with signedDownloads.shouldUseSignedURL you can specify a condition whether Payload should use a presigned URL, if you want to use this feature only for specific files.
