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 This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.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);

Initializer

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