This AWS Solutions Construct implements an AWS IoT MQTT topic rule and an AWS Lambda function pattern.

Here is a minimal deployable pattern definition in Typescript:

const { IotToLambdaProps, IotToLambda } from '@aws-solutions-constructs/aws-iot-lambda';

const props: IotToLambdaProps = {
    lambdaFunctionProps: {
        code: lambda.Code.fromAsset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_14_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 IotToLambda(this, 'test-iot-lambda-integration', props);
