This AWS Solutions Konstruk implements the AWS Lambda function and Amazon DynamoDB table with the least privileged permissions.

Here is a minimal deployable pattern definition:

const { LambdaToDynamoDBProps,  LambdaToDynamoDB } = require('@aws-solutions-konstruk/aws-lambda-dynamodb');

const props: LambdaToDynamoDBProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler'
    },
};

new LambdaToDynamoDB(stack, 'test-lambda-dynamodb-stack', props);

Initializer

new LambdaToDynamoDB(scope: Construct, id: string, props: LambdaToDynamoDBProps);

Parameters

scope Construct
id string
props LambdaToDynamoDBProps

Pattern Construct Props

Name	Type	Description
deployLambda	`boolean`	Whether to create a new Lambda function or use an existing Lambda function
existingLambdaObj?	`lambda.Function`	Existing instance of Lambda Function object
lambdaFunctionProps?	`lambda.FunctionProps`	Optional user provided props to override the default props for Lambda function
dynamoTableProps	`dynamodb.TableProps`	Optional user provided props to override the default props for DynamoDB Table

Pattern Properties

Name	Type	Description
lambdaFunction()	`lambda.Function`	Returns an instance of lambda.Function created by the construct
dynamoTable()	`dynamodb.Table`	Returns an instance of dynamodb.Table created by the construct
