Stability: Experimental

This is a developer preview (public beta) module.

All classes are under active development and subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.

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

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 Retruns an instance of lambda.Function created by the construct
