README

Lumen implementation for DynamoDB, based on Bao Pham's laravel-dynamodb.

Prerequisites

To install DynamoDB locally, see Running DynamoDB on Your Computer.

When DynamoDB is set up, start it with java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb

You can use the DynamoDB artisan command to manage the DynamoDB at the moment:

php artisan dynamodb:create --config=<TABLE_CONFIGURATION> # To create tables
php artisan dynamodb:delete --config=<TABLE_CONFIGURATION> -y # To delete tables

The table configuration file should return an array of table configurations:

return [
    [
        'TableName'             => 'users',
        'AttributeDefinitions'  => [
            [
                'AttributeName' => 'id',
                'AttributeType' => 'S',
            ],
        ],
        'KeySchema'             => [
            [
                'AttributeName' => 'id',
                'KeyType'       => 'HASH',
            ],
        ],
        'ProvisionedThroughput' => [
            'ReadCapacityUnits'  => 10,
            'WriteCapacityUnits' => 20,
            'OnDemand'           => false,
        ],
    ],
    [
        'TableName'             => 'orders',
        'AttributeDefinitions'  => [
            [
                'AttributeName' => 'id',
                'AttributeType' => 'S',
            ],
        ],
        'KeySchema'             => [
            [
                'AttributeName' => 'id',
                'KeyType'       => 'HASH',
            ],
        ],
        'ProvisionedThroughput' => [
            'ReadCapacityUnits'  => 10,
            'WriteCapacityUnits' => 20,
            'OnDemand'           => false,
        ],
    ],
];

If you don't want to use a configuration file, you may as well override the Create/DeleteTablesCommand and put your table definitions in the protected static $tables = [] array to override the tables.

Remember to add the overridden command in your Kernel.php file.

Install

// .env:
DYNAMODB_KEY=<AWS_KEY>
DYNAMODB_SECRET=<AWS_SECRET_KEY>
DYNAMODB_REGION=<AWS_REGION>
DYNAMODB_VERSION=latest
DYNAMODB_LOCAL_ENDPOINT=http://localhost:8000 # Only used for local DynamoDB


// config/services.php
return [
    ...
    'dynamodb' => [
        'key'      => env('DYNAMODB_KEY', 'dynamodb_local'),
        'secret'   => env('DYNAMODB_SECRET', 'secret'),
        'region'   => env('DYNAMODB_REGION', 'eu-central-1'),
        'version'  => env('DYNAMODB_VERSION', 'latest'),
        'endpoint' => env('DYNAMODB_LOCAL_ENDPOINT', 'http://localhost:8000'),
    ],
    ...
];

// bootstrap/app.php
...
$app->configure('services');
...
$app->register(Nord\Lumen\DynamoDb\DynamoDBServiceProvider::class);

Usage

Extend all your models from \Nord\Lumen\DynamoDb\Domain\Model\DynamoDbModel

You will need to set the following properties for your model to get the DynamoDbModel to work:

// The keys are defined when creating the table. If you are using only one primary key, set the $primaryKey,
// if using both primaryKey and sortKey, define the $compositeKey.
protected $primaryKey = '<primaryKey>'; // Ignore if using composite key.
protected $compositeKey = ['<primaryKey>', '<sortKey>']; // Ignore if you don't have a composite key.
protected $table = '<table_name>'; // Set the DynamoDB table this model uses
// If using global or local indexes, define the key => indexName values here.
protected $dynamoDbIndexKeys = [
    '<globalIndexKey>' => '<globalIndexName>',
    '<localIndexKey>' => '<localIndexName>',
];

// Set this to be able to mass assign attributes.
protected $fillable = ['email', 'name'];
protected $guarded = ['address'];

Using the models works pretty much in the same way as with Eloquent:

$model = DynamoDbModel::find(1); // Find a model with the primary key 1
// Using where:
$model = DynamoDbModel::where(['email' => '[e-mail]']);
$model->get()->first(); // Returns the first record.

$model = new DynamoDbModel(['name' => 'Demo user', 'email' => '[e-mail]']); // Fillable attributes.
$model->setAddress('Teststreet 1'); // Set the guarded attribute.
$model->save();
