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";

const props: SnsToLambdaProps = {
    lambdaFunctionProps: {
        runtime: lambda.Runtime.NODEJS_12_X,
        handler: 'index.handler',
        code: lambda.Code.asset(`${__dirname}/lambda`)
    }
};

new SnsToLambda(this, 'test-sns-lambda', props);

Initializer

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

Parameters

• scope Construct
• id string
• props S3ToLambdaProps
