This AWS Solutions Construct implements an AWS CloudFront fronting an Amazon API Gateway REST API.

Here is a minimal deployable pattern definition:

const api = require('@aws-cdk/aws-apigateway');
const lambda = require("@aws-cdk/aws-lambda");
const { CloudFrontToApiGateway } = require('@aws-solutions-constructs/aws-cloudfront-apigateway');

const stack = new Stack();

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

const lambdafunction = new lambda.Function(stack, 'LambdaFunction', lambdaProps);

const apiGatewayProps: api.LambdaRestApiProps = {
        handler: lambdafunction,
        endpointConfiguration: {
            types: [api.EndpointType.REGIONAL]
        },
        defaultMethodOptions: {
            authorizationType: api.AuthorizationType.NONE
        }
};

const apiGateway = new api.LambdaRestApi(scope, 'LambdaRestApi', apiGatewayProps);

new CloudFrontToApiGateway(stack, 'test-cloudfront-apigateway', {
    existingApiGatewayObj: apiGateway
});

Initializer

new CloudFrontToApiGateway(scope: Construct, id: string, props: CloudFrontToApiGatewayProps);

Parameters

• scope Construct
• id string
• props CloudFrontToApiGatewayProps

Pattern Construct Props

Name	Type	Description
existingApiGatewayObj	api.RestApi	The regional API Gateway that will be fronted with the CloudFront
cloudFrontDistributionProps?	[`cloudfront.CloudFrontWebDistributionProps	any`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-cloudfront.CloudFrontWebDistributionProps.html)
insertHttpSecurityHeaders?	boolean	Optional user provided props to turn on/off the automatic injection of best practice HTTP security headers in all responses from CloudFront

Pattern Properties

Name	Type	Description
cloudFrontWebDistribution	cloudfront.CloudFrontWebDistribution	Returns an instance of cloudfront.CloudFrontWebDistribution created by the construct
apiGateway	api.RestApi	Returns an instance of the API Gateway REST API created by the pattern.
edgeLambdaFunctionVersion	lambda.Version	Returns an instance of the edge Lambda function version created by the pattern.
cloudFrontLoggingBucket	s3.Bucket	Returns an instance of the logging bucket for CloudFront WebDistribution.

Default settings

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

Amazon CloudFront

• Configure Access logging for CloudFront WebDistribution
• Enable automatic injection of best practice HTTP security headers in all responses from CloudFront WebDistribution

Amazon API Gateway

• User provided API Gateway object is used as-is
• Enable X-Ray Tracing
