JSPM – @aws-solutions-constructs/aws-sns-lambda@1.96.0

Package Exports

@aws-solutions-constructs/aws-sns-lambda

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-sns-lambda) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Java	`software.amazon.awsconstructs.services.snslambda`

This AWS Solutions Construct implements an Amazon SNS connected to an AWS Lambda function.

Here is a minimal deployable pattern definition in Typescript:

import { SnsToLambda, SnsToLambdaProps } from "@aws-solutions-constructs/aws-sns-lambda";

new SnsToLambda(this, 'test-sns-lambda', {
    lambdaFunctionProps: {
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler',
        code: lambda.Code.fromAsset(`${__dirname}/lambda`)
    }
});

Initializer

new SnsToLambda(scope: Construct, id: string, props: SnsToLambdaProps);

Parameters

scope Construct
id string
props S3ToLambdaProps

Pattern Construct Props

Name	Type	Description
existingLambdaObj?	`lambda.Function`	Existing instance of Lambda Function object, if this is set then the lambdaFunctionProps is ignored.
lambdaFunctionProps?	`lambda.FunctionProps`	User provided props to override the default props for the Lambda function.
existingTopicObj?	`sns.Topic`	Existing instance of SNS Topic object, if this is set then the topicProps is ignored.
topicProps?	`sns.TopicProps`	Optional user provided properties to override the default properties for the SNS topic.

Pattern Properties

Name	Type	Description
lambdaFunction	`lambda.Function`	Returns an instance of the Lambda function created by the pattern.
snsTopic	`sns.Topic`	Returns an instance of the SNS topic created by the pattern.

Default settings

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

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

AWS Lambda Function

Configure limited privilege access IAM role for Lambda function
Enable reusing connections with Keep-Alive for NodeJs Lambda function
Enable X-Ray Tracing
Set Environment Variables
- AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
