# elm-aws-core

**This is a Fork** from [the-sett/elm-aws-core](https://github.com/the-sett/elm-aws-core).
It fixes the handling of `signingName` and `"Content-Type"` for `REST_JSON` requests.

This package provides the functionality needed to make HTTP requests to AWS
services.

All AWS service calls must be signed correctly, in order to pass on the
authorized credentials of the caller to the service. AWS has multiple signing
schemes that different services use, specifically 'S3' and 'V4'.

The AWS service portfolio is large with variations in signing schemes, AWS
regions and service protocols across it. The aim of this package is to provide
functions to build signed HTTP requests correctly for all of the services
available on AWS. The specific service interface can then be implemented with
this package as a foundational element.

## Modules in this package

  - [AWS.Config](AWS-Config): Build a `ServiceConfig` describing the
  protocol, signing scheme, base URL and so on for a service.
  - [AWS.Service](AWS-Service): Turn a `ServiceConfig` into a `Service`
  definition, needed to make HTTP calls to that service.
  - [AWS.Http](AWS-Http): Build requests, sign and send them and decode the
  responses. Signing and sending a request requires both a `Service` and
  some `Credentials`.
  - [AWS.Credentials](AWS-Credentials): Create AWS `Credentials` used to sign
  requests.
  - [AWS.KVEncode](AWS-KVEncode): Utility for helping to encode Elm data into
  key-valued string pairs, for setting query parameters or header fields.
  - [AWS.KVDecode](AWS-KVDecode): Utility for decoding key-values string pairs
  into Elm data. Simpler than `KVEncode` as only needed for interpreting fairly
  simple response headers.
  - [AWS.Uri](AWS-Uri): Utility for URI encoding specific to how AWS does it.
