I just published an S3 storage provider for Elasticlunr. You can now store your indexes to an S3 bucket aside the Disk storage provider included in the base project.

The storage API is flexible, so writing to any storage provider (Google Cloud Storage, DB and so on) shouldn’t be a problem. it’s just a matter of grabbing the right provider or implementing one yourself.
