# aws-lambda-sns module --- ![Stability: Stable](https://img.shields.io/badge/cfn--resources-stable-success.svg?style=for-the-badge) ---  | **Reference Documentation**:| <span style="font-weight: normal">https://docs.aws.amazon.com/solutions/latest/constructs/</span>| |:-------------|:-------------| <div style="height:8px"></div> | **Language** | **Package** | |:-------------|-----------------| |![Python Logo](https://docs.aws.amazon.com/cdk/api/latest/img/python32.png) Python|`aws_solutions_constructs.aws_lambda_sns`| |![Typescript Logo](https://docs.aws.amazon.com/cdk/api/latest/img/typescript32.png) Typescript|`@aws-solutions-constructs/aws-lambda-sns`| |![Java Logo](https://docs.aws.amazon.com/cdk/api/latest/img/java32.png) Java|`software.amazon.awsconstructs.services.lambdasns`| ## Overview This AWS Solutions Construct implements an AWS Lambda function connected to an Amazon SNS topic. Here is a minimal deployable pattern definition: Typescript ```python import { Construct } from 'constructs'; import { Stack, StackProps } from 'aws-cdk-lib'; import { LambdaToSns, LambdaToSnsProps } from "@aws-solutions-constructs/aws-lambda-sns"; import * as lambda from 'aws-cdk-lib/aws-lambda'; new LambdaToSns(this, 'test-lambda-sns', { lambdaFunctionProps: { runtime: lambda.Runtime.NODEJS_16_X, handler: 'index.handler', code: lambda.Code.fromAsset(`lambda`) } }); ``` Python ```python from aws_solutions_constructs.aws_lambda_sns import LambdaToSns from aws_cdk import ( aws_lambda as _lambda, Stack ) from constructs import Construct LambdaToSns( self, 'test-lambda-sns-stack', lambda_function_props=_lambda.FunctionProps( code=_lambda.Code.from_asset('lambda'), runtime=_lambda.Runtime.PYTHON_3_9, handler='index.handler' ) ) ``` Java ```java import software.constructs.Construct; import software.amazon.awscdk.Stack; import software.amazon.awscdk.StackProps; import software.amazon.awscdk.services.lambda.*; import software.amazon.awscdk.services.lambda.Runtime; import software.amazon.awsconstructs.services.lambdasns.*; new LambdaToSns(this, "test-lambda-sns-stack", new LambdaToSnsProps.Builder() .lambdaFunctionProps(new FunctionProps.Builder() .runtime(Runtime.NODEJS_16_X) .code(Code.fromAsset("lambda")) .handler("index.handler") .build()) .build()); ``` ## Pattern Construct Props | **Name** | **Type** | **Description** | |:-------------|:----------------|-----------------| |existingLambdaObj?|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.Function.html)|Existing instance of Lambda Function object, providing both this and `lambdaFunctionProps` will cause an error.| |lambdaFunctionProps?|[`lambda.FunctionProps`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.FunctionProps.html)|User provided props to override the default props for the Lambda function.| |existingTopicObj?|[`sns.Topic`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.Function.html)|Existing instance of SNS Topic object, providing both this and `topicProps` will cause an error.| |topicProps?|[`sns.TopicProps`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_sns.TopicProps.html)|Optional user provided properties to override the default properties for the SNS topic.| |existingVpc?|[`ec2.IVpc`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.IVpc.html)|An optional, existing VPC into which this pattern should be deployed. When deployed in a VPC, the Lambda function will use ENIs in the VPC to access network resources and an Interface Endpoint will be created in the VPC for Amazon SNS. If an existing VPC is provided, the `deployVpc` property cannot be `true`. This uses `ec2.IVpc` to allow clients to supply VPCs that exist outside the stack using the [`ec2.Vpc.fromLookup()`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.Vpc.html#static-fromwbrlookupscope-id-options) method.| |vpcProps?|[`ec2.VpcProps`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.VpcProps.html)|Optional user-provided properties to override the default properties for the new VPC. `enableDnsHostnames`, `enableDnsSupport`, `natGateways` and `subnetConfiguration` are set by the pattern, so any values for those properties supplied here will be overrriden. If `deployVpc` is not `true` then this property will be ignored.| |deployVpc?|`boolean`|Whether to create a new VPC based on `vpcProps` into which to deploy this pattern. Setting this to true will deploy the minimal, most private VPC to run the pattern:<ul><li> One isolated subnet in each Availability Zone used by the CDK program</li><li>`enableDnsHostnames` and `enableDnsSupport` will both be set to true</li></ul>If this property is `true` then `existingVpc` cannot be specified. Defaults to `false`.| |topicArnEnvironmentVariableName?|`string`|Optional Name for the Lambda function environment variable set to the arn of the topic. Default: SNS_TOPIC_ARN | |topicNameEnvironmentVariableName?|`string`|Optional Name for the Lambda function environment variable set to the name of the topic. Default: SNS_TOPIC_NAME | |enableEncryptionWithCustomerManagedKey?|`boolean`|If no key is provided, this flag determines whether the SNS Topic is encrypted with a new CMK or an AWS managed key. This flag is ignored if any of the following are defined: topicProps.masterKey, encryptionKey or encryptionKeyProps.| |encryptionKey?|[`kms.Key`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_kms.Key.html)|An optional, imported encryption key to encrypt the SNS Topic with.| |encryptionKeyProps?|[`kms.KeyProps`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_kms.Key.html#construct-props)|Optional user provided properties to override the default properties for the KMS encryption key used to encrypt the SNS Topic with.| ## Pattern Properties | **Name** | **Type** | **Description** | |:-------------|:----------------|-----------------| |lambdaFunction|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.Function.html)|Returns an instance of the Lambda function created by the pattern.| |snsTopic|[`sns.Topic`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_sns.Topic.html)|Returns an instance of the SNS topic created by the pattern.| |vpc?|[`ec2.IVpc`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.IVpc.html)|Returns an interface on the VPC used by the pattern (if any). This may be a VPC created by the pattern or the VPC supplied to the pattern constructor.| ## Default settings Out of the box implementation of the Construct without any override will set the following defaults: ### AWS Lambda Function * Configure limited privilege access IAM role for Lambda function to access the Firehose Delivery Stream * Enable reusing connections with Keep-Alive for NodeJs Lambda function * Enable X-Ray Tracing * Set Environment Variables * (default) SNS_TOPIC_NAME * (default) SNS_TOPIC_ARN * AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions) ### Amazon SNS Topic * Configure least privilege access permissions for SNS Topic * Enable server-side encryption forSNS Topic using AWS managed KMS Key * Enforce encryption of data in transit ## Architecture ![Architecture Diagram](architecture.png) --- © Copyright Amazon.com, Inc. or its affiliates.
