AWS clients for Elixir

Actions Status Module Version Hex Docs Total Download License Last Updated

🌳 With this library you can have access to almost all AWS services without hassle. ⚡

Features

  • A clean API separated per service. Each module has a correspondent service.
  • Support for most of AWS services.
  • Configurable HTTP client and JSON parser.
  • Generated by aws-codegen using the same JSON descriptions of AWS services used to build the AWS SDK for Go.
  • Documentation is updated from the official AWS docs.

Usage

Here is an example of listing Amazon Kinesis streams. First you need to start a console with iex -S mix.

After that, type the following:

iex> client = AWS.Client.create("your-access-key-id", "your-secret-access-key", "us-east-1")
iex> {:ok, result, resp} = AWS.Kinesis.list_streams(client, %{})
iex> IO.inspect(result)
%{"HasMoreStreams" => false, "StreamNames" => []}

If you are using Amazon.S3, you can upload a file with integrity check doing:

iex> client = AWS.Client.create("your-access-key-id", "your-secret-access-key", "us-east-1")
iex> file =  File.read!("./tmp/your-file.txt")
iex> md5 = :crypto.hash(:md5, file) |> Base.encode64()
iex> AWS.S3.put_object(client, "your-bucket-name", "foo/your-file-on-s3.txt",
  %{"Body" => file, "ContentMD5" => md5})

Note that you may need to specify the ContentType attribute when calling AWS.S3.put_object/4. This is because S3 will use that to store the MIME type of the file.

Remember to check the operation documentation for details: https://docs.aws.amazon.com/

Installation

Add :aws to your list of dependencies in mix.exs. It also requires hackney for the default HTTP client. Optionally, you can implement your own (Check AWS.Client docs).

def deps do
  [
    {:aws, "~> 0.8.0"},
    {:hackney, "~> 1.17"}
  ]
end

Run mix deps.get to install.

Development

Most of the code is generated using the aws-codegen library from the JSON descriptions of AWS services provided by Amazon. They can be found in lib/aws/generated.

Code outside lib/aws/generated is manually written and used as support for the generated code.

Documentation

Online

Local

  • Run mix docs
  • Open docs/index.html

Note: Arguments, errors and response structure can be found by viewing the model schemas used to generate this module at aws-sdk-go/models/apis/<aws-service>/<version>/.

An example is aws-sdk-go/models/apis/rekognition/2016-06-27/api-2.json. Alternatively you can access the documentation for the service you want at AWS docs page.

Tests

$ mix test

Release

  • Make sure the CHANGELOG.md is up-to-date and and reflects the changes for the new version.
  • Bump the version here in the README.md and in mix.exs.
  • Run git tag v$VERSION to tag the version that was just published.
  • Run git push --tags origin master to push tags to Github.
  • Run mix hex.publish to publish the new version.
