bucket

Gleam S3 API client, suitable for AWS S3, Garage, Minio, Storj, Backblaze B2, Cloudflare R2, Ceph, Wasabi, and so on!

This package uses the sans-io approach, meaning it does not send HTTP requests itself, instead it gives you functions for creating HTTP requests for and decoding HTTP responses from an S3 API, and you send the requests with a HTTP client of your choosing.

This HTTP client independence gives you full control over HTTP, and means this library can be used on both the Erlang and JavaScript runtimes.
