Service module for https://github.com/ex-aws/ex_aws
The package can be installed by adding :ex_aws_dynamo to your list of dependencies in mix.exs along with your preferred JSON codec and HTTP client:
def deps do
[
{:ex_aws_dynamo, "~> 4.0"},
{:jason, "~> 1.0"},
{:hackney, "~> 1.9"}
]
endExAws uses Jason as its default JSON codec - if you intend to use a different codec, see ex_aws for more information about setting a custom :json_codec.
Documentation for ExAwsDynamo can be found at https://hexdocs.pm/ex_aws_dynamo.
If you are running this module against a local development instance of DynamoDB, you'll want to make sure that you have installed the latest version, 1.17.2 (released 2021-12-16). You can find links to download the latest version here.
In order to use ExAws.Dynamo against a production instance of DynamoDB, your app will need to provide the following configuration for :ex_aws:
Example configuration:
config :ex_aws,
access_key_id: [{:system, "AWS_ACCESS_KEY_ID"}, :instance_role],
secret_access_key: [{:system, "AWS_SECRET_ACCESS_KEY"}, :instance_role]:access_key_id :: string
The ID portion of a set of AWS credentials.
:secret_access_key :: string
The secret portion of a set of AWS credentials.
Please see the ExAws README for additional reference.
The tests in test/lib/dynamo/integration_test.exs will attempt to run against a local instance of DynamoDB - in order to run these tests, you will need both a running local instance of DynamoDB as well as a config/ddb_local_test.exs file (.gitignored) formatted like so:
config/ddb_local_test.exs
import Config
config :ex_aws,
debug_requests: false, # set to true to monitor the DDB requests
access_key_id: "abcd",
secret_access_key: "1234",
region: "us-east-1"
config :ex_aws, :dynamodb,
scheme: "http://",
host: "localhost",
port: SET_YOUR_PORT,
region: "us-east-1"(or see config/ddb_local_test.exs.example)
Before running tests, be aware that test/lib/dynamo/integration_test.exs will create and delete tables with the names "TestUsers", "Test.User", "TestSeveralUsers", "TestFoo", "test_books", "TestUsersWithRange", "TestTransactions", "TestTransactions2" - test operations may affect your current tables if they share any of those names. You may consider maintaining a separate instance of DynamoDB local (or at least a separate instance of its shared-local-instance.db file) for testing.
If DynamoDB is not running locally or the config file has not been provided, the integration tests will be skipped.
