Functions

func EdgeFunction_IsConstruct

func EdgeFunction_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func EdgeFunction_IsOwnedResource

func EdgeFunction_IsOwnedResource(construct constructs.IConstruct) *bool

Returns true if the construct was created by CDK, and false otherwise.

func EdgeFunction_IsResource

func EdgeFunction_IsResource(construct constructs.IConstruct) *bool

Check whether the given construct is a Resource.

A Lambda@Edge function.

Convenience resource for requesting a Lambda function in the 'us-east-1' region for use with Lambda@Edge. Implements several restrictions enforced by Lambda@Edge.

Note that this construct requires that the 'us-east-1' region has been bootstrapped. See https://docs.aws.amazon.com/cdk/latest/guide/bootstrapping.html or 'cdk bootstrap --help' for options.

Example:

var myBucket bucket
// A Lambda@Edge function added to default behavior of a Distribution
// and triggered on every request
myFunc := experimental.NewEdgeFunction(this, jsii.String("MyFunction"), &EdgeFunctionProps{
	Runtime: lambda.Runtime_NODEJS_LATEST(),
	Handler: jsii.String("index.handler"),
	Code: lambda.Code_FromAsset(path.join(__dirname, jsii.String("lambda-handler"))),
})
cloudfront.NewDistribution(this, jsii.String("myDist"), &DistributionProps{
	DefaultBehavior: &BehaviorOptions{
		Origin: origins.NewS3Origin(myBucket),
		EdgeLambdas: []edgeLambda{
			&edgeLambda{
				FunctionVersion: myFunc.currentVersion,
				EventType: cloudfront.LambdaEdgeEventType_VIEWER_REQUEST,

Properties for creating a Lambda@Edge function.

Example:

var myBucket bucket
// A Lambda@Edge function added to default behavior of a Distribution
// and triggered on every request
myFunc := experimental.NewEdgeFunction(this, jsii.String("MyFunction"), &EdgeFunctionProps{
	Runtime: lambda.Runtime_NODEJS_LATEST(),
	Handler: jsii.String("index.handler"),
	Code: lambda.Code_FromAsset(path.join(__dirname, jsii.String("lambda-handler"))),
})
cloudfront.NewDistribution(this, jsii.String("myDist"), &DistributionProps{
	DefaultBehavior: &BehaviorOptions{
		Origin: origins.NewS3Origin(myBucket),
		EdgeLambdas: []edgeLambda{
			&edgeLambda{
				FunctionVersion: myFunc.currentVersion,
				EventType: cloudfront.LambdaEdgeEventType_VIEWER_REQUEST,
			},
		},
	},
})
