Overview

This AWS Solutions Construct implements an Amazon API Gateway REST API connected to an AWS Lambda function pattern.

Here is a minimal deployable pattern definition:

const { ApiGatewayToLambda } = require('@aws-solutions-constructs/aws-apigateway-lambda');

new ApiGatewayToLambda(stack, 'ApiGatewayToLambdaPattern', {
    lambdaFunctionProps: {
        runtime: lambda.Runtime.NODEJS_10_X,
        handler: 'index.handler',
        code: lambda.Code.asset(`${__dirname}/lambda`)
    }
});

Initializer

new ApiGatewayToLambda(scope: Construct, id: string, props: ApiGatewayToLambdaProps);

Parameters

• scope Construct
• id string
• props ApiGatewayToLambdaProps

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.
apiGatewayProps?	api.LambdaRestApiProps	Optional user-provided props to override the default props for the API.

Pattern Properties

Name	Type	Description
lambdaFunction	lambda.Function	Returns an instance of the Lambda function created by the pattern.
restApi	api.LambdaRestApi	Returns an instance of the API Gateway REST API created by the pattern.
apiGatewayCloudWatchRole	iam.Role	Returns an instance of the iam.Role created by the construct for API Gateway for CloudWatch access.
apiGatewayLogGroup	logs.LogGroup	Returns an instance of the LogGroup created by the construct for API Gateway access logging to CloudWatch.

Default settings

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

Amazon API Gateway

• Deploy an edge-optimized API endpoint
• Enable CloudWatch logging for API Gateway
• Configure least privilege access IAM role for API Gateway
• Set the default authorizationType for all API methods to IAM

AWS Lambda Function

• Configure least privilege access IAM role for Lambda function
• Enable reusing connections with Keep-Alive for NodeJs Lambda function
