AWS IoT Construct Library

AWS CDK v1 has reached End-of-Support on 2023-06-01. This package is no longer being updated, and users should migrate to AWS CDK v2.
For more information on how to migrate, see the Migrating to AWS CDK v2 guide.

AWS IoT Core lets you connect billions of IoT devices and route trillions of messages to AWS services without managing infrastructure.

Installation

Install the module:

$ npm i @aws-cdk/aws-iot

Import it into your code:

import * as iot from '@aws-cdk/aws-iot';
import * as actions from '@aws-cdk/aws-iot-actions';

`TopicRule`

Create a topic rule that give your devices the ability to interact with AWS services. You can create a topic rule with an action that invoke the Lambda action as following:

const func = new lambda.Function(this, 'MyFunction', {
  runtime: lambda.Runtime.NODEJS_14_X,
  handler: 'index.handler',
  code: lambda.Code.fromInline(`
    exports.handler = (event) => {
      console.log("It is test for lambda action of AWS IoT Rule.", event);
    };`
  ),
});

new iot.TopicRule(this, 'TopicRule', {
  topicRuleName: 'MyTopicRule', // optional
  description: 'invokes the lambda function', // optional
  sql: iot.IotSql.fromStringAsVer20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
  actions: [new actions.LambdaFunctionAction(func)],
});

Or, you can add an action after constructing the TopicRule instance as following:

declare const func: lambda.Function;

const topicRule = new iot.TopicRule(this, 'TopicRule', {
  sql: iot.IotSql.fromStringAsVer20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
});
topicRule.addAction(new actions.LambdaFunctionAction(func));

You can also supply errorAction as following, and the IoT Rule will trigger it if a rule's action is unable to perform:

import * as logs from '@aws-cdk/aws-logs';

const logGroup = new logs.LogGroup(this, 'MyLogGroup');

new iot.TopicRule(this, 'TopicRule', {
  sql: iot.IotSql.fromStringAsVer20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
  errorAction: new actions.CloudWatchLogsAction(logGroup),
});

If you wanna make the topic rule disable, add property enabled: false as following:

new iot.TopicRule(this, 'TopicRule', {
  sql: iot.IotSql.fromStringAsVer20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
  enabled: false,
});

See also @aws-cdk/aws-iot-actions for other actions.
