CDK Constructs for AWS IoT to AWS Lambda integration

Project description

aws-iot-lambda 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 This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.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 MQTT topic rule and an AWS Lambda function pattern.

Here is a minimal deployable pattern definition:

const { IotToLambdaProps, IotToLambda } = require('@aws-solutions-konstruk/aws-iot-lambda');

const props: IotToLambdaProps = {
    deployLambda: true,
    lambdaFunctionProps: {
        code: lambda.Code.asset(`${__dirname}/lambda`),
        runtime: lambda.Runtime.NODEJS_10_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(stack, 'test-iot-lambda-integration', props);


new IotToLambda(scope: Construct, id: string, props: IotToLambdaProps);


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 CfnTopicRuleProps to override the defaults

Pattern Properties

Name Type Description
iotTopicRule() iot.CfnTopicRule Retruns an instance of iot.CfnTopicRule created by the construct
lambdaFunction() lambda.Function Retruns an instance of lambda.Function created by the construct
