JSPM – @aws-solutions-constructs/aws-events-rule-sns@1.64.1

Package Exports

@aws-solutions-constructs/aws-events-rule-sns

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@aws-solutions-constructs/aws-events-rule-sns) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

This AWS Solutions Construct implements an AWS Events rule and an AWS SNS Topic.

Here is a minimal deployable pattern definition in Typescript:

import { EventsRuleToSNSProps, EventsRuleToSNS } from "@aws-solutions-constructs/aws-events-rule-sns";

const props: EventsRuleToSNSProps = {
    eventRuleProps: {
      schedule: events.Schedule.rate(Duration.minutes(5)),
    }
};

const constructStack = new EventsRuleToSNS(this, 'test-events-rule-sns', props);

// Grant yourself permissions to use the Customer Managed KMS Key
const policyStatement = new iam.PolicyStatement({
    actions: ["kms:Encrypt", "kms:Decrypt"],
    effect: iam.Effect.ALLOW,
    principals: [ new iam.AccountRootPrincipal() ],
    resources: [ "*" ]
});

constructStack.encryptionKey?.addToResourcePolicy(policyStatement);

Initializer

new EventsRuleToSNS(scope: Construct, id: string, props: EventsRuleToSNSProps);

Parameters

scope Construct
id string
props EventsRuleToSNSProps

Pattern Construct Props

Name	Type	Description
eventRuleProps	`events.RuleProps`	User provided eventRuleProps to override the defaults.
existingTopicObj?	`sns.Topic`	Existing instance of SNS Topic object, if this is set then the topicProps is ignored.
topicProps?	`sns.TopicProps`	User provided props to override the default props for the SNS Topic.
enableEncryptionWithCustomerManagedKey?	`boolean`	Use a KMS Key, either managed by this CDK app, or imported. If importing an encryption key, it must be specified in the encryptionKey property for this construct.
encryptionKey?	`kms.Key`	An optional, imported encryption key to encrypt the SNS Topic.
encryptionKeyProps?	`kms.KeyProps`	An optional, user provided properties to override the default properties for the KMS encryption key.

Pattern Properties

Name	Type	Description
eventsRule	`events.Rule`	Returns an instance of events.Rule created by the construct
snsTopic	`sns.Topic`	Returns an instance of sns.Topic created by the construct
encryptionKey?	`kms.Key`	Returns an instance of kms Key used for the SNS Topic.

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

Amazon CloudWatch Events Rule

Grant least privilege permissions to CloudWatch Events to publish to the SNS Topic.

Configure least privilege access permissions for SNS Topic.
Enable server-side encryption forSNS Topic using Customer managed KMS Key.
Enforce encryption of data in transit.
