AWS IoT Construct Library

---

The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.

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

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:

func := lambda.NewFunction(this, jsii.String("MyFunction"), &FunctionProps{
	Runtime: lambda.Runtime_NODEJS_LATEST(),
	Handler: jsii.String("index.handler"),
	Code: lambda.Code_FromInline(jsii.String(`
	    exports.handler = (event) => {
	      console.log("It is test for lambda action of AWS IoT Rule.", event);
	    };`)),
})

iot.NewTopicRule(this, jsii.String("TopicRule"), &TopicRuleProps{
	TopicRuleName: jsii.String("MyTopicRule"),
	 // optional
	Description: jsii.String("invokes the lambda function"),
	 // optional
	Sql: iot.IotSql_FromStringAsVer20160323(jsii.String("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'")),
	Actions: []iAction{
		actions.NewLambdaFunctionAction(func),
	},
})

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

var func function


topicRule := iot.NewTopicRule(this, jsii.String("TopicRule"), &TopicRuleProps{
	Sql: iot.IotSql_FromStringAsVer20160323(jsii.String("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'")),
})
topicRule.AddAction(actions.NewLambdaFunctionAction(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 logs "github.com/aws/aws-cdk-go/awscdk"


logGroup := logs.NewLogGroup(this, jsii.String("MyLogGroup"))

iot.NewTopicRule(this, jsii.String("TopicRule"), &TopicRuleProps{
	Sql: iot.IotSql_FromStringAsVer20160323(jsii.String("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'")),
	ErrorAction: actions.NewCloudWatchLogsAction(logGroup),
})

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

iot.NewTopicRule(this, jsii.String("TopicRule"), &TopicRuleProps{
	Sql: iot.IotSql_FromStringAsVer20160323(jsii.String("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'")),
	Enabled: jsii.Boolean(false),
})

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

Functions

func NewIotSql_Override 

func NewIotSql_Override(i IotSql)

Experimental.

func NewTopicRule_Override 

func NewTopicRule_Override(t TopicRule, scope constructs.Construct, id *string, props *TopicRuleProps)

Experimental.

func TopicRule_IsConstruct 

func TopicRule_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`. Experimental.

func TopicRule_IsOwnedResource 

func TopicRule_IsOwnedResource(construct constructs.IConstruct) *bool

Returns true if the construct was created by CDK, and false otherwise. Experimental.

func TopicRule_IsResource 

func TopicRule_IsResource(construct constructs.IConstruct) *bool

Check whether the given construct is a Resource. Experimental.

	// The configuration for this action.
	// Experimental.

type TopicRule 

type TopicRule interface {
	awscdk.Resource

	// this is always the same as the environment of the stack they belong to;

	// The tree node.
	// Experimental.
	Node() constructs.Node
	// Returns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.
	//
	// This value will resolve to one of the following:
	// - a concrete value (e.g. `"my-awesome-bucket"`)
	// - `undefined`, when a name should be generated by CloudFormation
	// - a concrete name generated automatically during synthesis, in
	//   cross-environment scenarios.

	// CDK application or because you've made a change that requires the resource
	// to be replaced.
	//
	// The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
	// account for data recovery and cleanup later (`RemovalPolicy.RETAIN`).
	// Experimental.
	ApplyRemovalPolicy(policy awscdk.RemovalPolicy)
	// Experimental.
	GeneratePhysicalName() *string
	// Returns an environment-sensitive token that should be used for the resource's "ARN" attribute (e.g. `bucket.bucketArn`).
	//
	// Normally, this token will resolve to `arnAttr`, but if the resource is
	// referenced across environments, `arnComponents` will be used to synthesize
	// a concrete ARN with the resource's physical name. Make sure to reference
	// `this.physicalName` in `arnComponents`.
	// Experimental.
	GetResourceArnAttribute(arnAttr *string, arnComponents *awscdk.ArnComponents) *string
	// Returns an environment-sensitive token that should be used for the resource's "name" attribute (e.g. `bucket.bucketName`).
	//
	// Normally, this token will resolve to `nameAttr`, but if the resource is
	// referenced across environments, it will be resolved to `this.physicalName`,
	// which will be a concrete name.

func NewTopicRule 

func NewTopicRule(scope constructs.Construct, id *string, props *TopicRuleProps) TopicRule

	// Experimental.
	Sql IotSql `field:"required" json:"sql" yaml:"sql"`

	Enabled *bool `field:"optional" json:"enabled" yaml:"enabled"`
	// The action AWS IoT performs when it is unable to perform a rule's action.
	// Default: - no action will be performed.
	//
	// Experimental.
	ErrorAction IAction `field:"optional" json:"errorAction" yaml:"errorAction"`
	// The name of the topic rule.
	// Default: None.
