Reference Documentation:	https://docs.aws.amazon.com/solutions/latest/constructs/

Language	Package
Python	`aws_solutions_constructs.aws_cloudfront_apigateway`
Typescript	`@aws-solutions-constructs/aws-cloudfront-apigateway`
Java	`software.amazon.awsconstructs.services.cloudfrontapigateway`

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

Here is a minimal deployable pattern definition in Typescript:

import * as api from '@aws-cdk/aws-apigateway';
import * as lambda from "@aws-cdk/aws-lambda";
import { CloudFrontToApiGateway } from '@aws-solutions-constructs/aws-cloudfront-apigateway';

const lambdaProps: lambda.FunctionProps = {
    code: lambda.Code.fromAsset(`${__dirname}/lambda`),
    runtime: lambda.Runtime.NODEJS_14_X,
    handler: 'index.handler'
};

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

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

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

new CloudFrontToApiGateway(this, '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.DistributionProps \\| any`	Optional user provided props to override the default props for CloudFront Distribution
insertHttpSecurityHeaders?	`boolean`	Optional user provided props to turn on/off the automatic injection of best practice HTTP security headers in all responses from CloudFront
cloudFrontLoggingBucketProps?	`s3.BucketProps`	Optional user provided props to override the default props for the CloudFront Logging Bucket.

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.
cloudFrontFunction?	`cloudfront.Function`	Returns an instance of the Cloudfront function 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
