@Generated(value="jsii-pacmak/1.121.0 (build d7af9b9)", date="2025-12-18T18:20:06.521Z") @Stability(Stable) public class CfnFunction extends CfnResource implements IInspectable, IFunctionRef
Creates a CloudFront function.

To create a function, you provide the function code and some configuration information about the function. The response contains an Amazon Resource Name (ARN) that uniquely identifies the function, and the function’s stage.

By default, when you create a function, it’s in the DEVELOPMENT stage. In this stage, you can test the function in the CloudFront console (or with TestFunction in the CloudFront API).

When you’re ready to use your function with a CloudFront distribution, publish the function to the LIVE stage. You can do this in the CloudFront console, with PublishFunction in the CloudFront API, or by updating the AWS::CloudFront::Function resource with the AutoPublish property set to true . When the function is published to the LIVE stage, you can attach it to a distribution’s cache behavior, using the function’s ARN.

To automatically publish the function to the LIVE stage when it’s created, set the AutoPublish property to true .

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.cloudfront.*;
 CfnFunction cfnFunction = CfnFunction.Builder.create(this, "MyCfnFunction")
         .functionCode("functionCode")
         .functionConfig(FunctionConfigProperty.builder()
                 .comment("comment")
                 .runtime("runtime")
                 // the properties below are optional
                 .keyValueStoreAssociations(List.of(KeyValueStoreAssociationProperty.builder()
                         .keyValueStoreArn("keyValueStoreArn")
                         .build()))
                 .build())
         .name("name")
         // the properties below are optional
         .autoPublish(false)
         .functionMetadata(FunctionMetadataProperty.builder()
                 .functionArn("functionArn")
                 .build())
         .build();
