# Amazonite AWS SDK
![example workflow](https://github.com/rjnienaber/amazonite/actions/workflows/ci.yml/badge.svg)

Amazonite is an unofficial AWS SDK for Crystal.

## Usage

Here's an example that creates a table in DynamoDB:

```crystal
require "amazonite/dynamodb_v2"

private alias DB = Amazonite::DynamoDBV2

model = DB::CreateTableInput.new(
[
DB::AttributeDefinition.new("Artist", DB::ScalarAttributeType::S),
DB::AttributeDefinition.new("SongTitle", DB::ScalarAttributeType::S)
],
"Music",
[
DB::KeySchemaElement.new("Artist", DB::KeyType::Hash),
DB::KeySchemaElement.new("SongTitle", DB::KeyType::Range)
],
provisioned_throughput: DB::ProvisionedThroughput.new(10, 5),
)

client = DB::Client.new # read credentials from environment variables
response = client.create_table(model)

puts response.http.status_code # 200
result = response.result
puts result.table_description.try &.table_name # Music
puts result.table_description.try &.attribute_definitions.try &.[0].attribute_name # Artist
```

Output:
```
200
Music
Artist
```
