Overview
This AWS Solutions Construct implements an AWS CloudFront fronting an Amazon API Gateway REST API.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { CloudFrontToApiGateway } from '@aws-solutions-constructs/aws-cloudfront-apigateway';
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as api from 'aws-cdk-lib/aws-apigateway';
const lambdaProps: lambda.FunctionProps = {
code: lambda.Code.fromAsset(`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
});
Python

api_gateway = api.LambdaRestApi(self, 'LambdaRestApi',
handler=lambda_function,
endpoint_configuration=api.EndpointConfiguration(

default_method_options=api.MethodOptions(

))
CloudFrontToApiGateway(self, 'test-cloudfront-apigateway',

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
