Project description

aws-iot-lambda-dynamodb module


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 This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.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 an AWS IoT topic rule, an AWS Lambda function and Amazon DynamoDB table with the least privileged permissions.

Here is a minimal deployable pattern definition:

const { IotToLambdaToDynamoDBProps,  IotToLambdaToDynamoDB } = require('@aws-solutions-konstruk/aws-iot-lambda-dynamodb');

const props: IotToLambdaToDynamoDBProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler'
    iotTopicRuleProps: {
        topicRulePayload: {
            ruleDisabled: false,
            description: "Processing of DTC messages from the AWS Connected Vehicle Solution.",
            sql: "SELECT * FROM 'connectedcar/dtc/#'",
            actions: []

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


new IotToLambdaToDynamoDB(scope: Construct, id: string, props: IotToLambdaToDynamoDBProps);


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
iotTopicRuleProps iot.CfnTopicRuleProps User provided props to override the default props
dynamoTableProps? dynamodb.TableProps Optional user provided props to override the default props for DynamoDB Table

Pattern Properties

Name Type Description
iotTopicRule() iot.CfnTopicRule Returns an instance of iot.CfnTopicRule created by the construct
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
