This is the AWS CDK v2 Developer Guide. The older CDK v1 entered maintenance on June 1, 2022 and ended support on June 1, 2023.
The AWS CDK libraries
Learn about the core libraries that you will use with the AWS Cloud Development Kit (AWS CDK).
The AWS CDK Library
The AWS CDK Library, also referred to as aws-cdk-lib, is the main library that you will use to develop
applications with the AWS CDK. It is developed and maintained by AWS. This library contains base classes, such as
App and Stack. It also contains the
libraries you will use to define your infrastructure through constructs.
The AWS Construct Library
The AWS Construct Library is a part of the AWS CDK Library. It contains a collection of constructs that are developed and maintained by AWS. It is organized into various modules for each AWS service. Each module includes constructs that you can use to define your AWS resources and properties.
The Constructs library
The Constructs library, commonly referred to as constructs, is a library for defining and composing
cloud infrastructure components. It contains the core Construct class, which represents the construct
building block. This class is the foundational base class of all constructs from the AWS Construct Library. The Constructs
library is a separate general-purpose library that is used by other construct-based tools such as CDK
for Terraform and CDK for Kubernetes.
The AWS CDK API reference
The AWS CDK API reference contains official reference documentation for the AWS CDK Library, including the AWS Construct Library and Constructs library. A version of the API refernce is provided for each supported programming language.

For AWS CDK Library (
aws-cdk-lib) documentation, see aws-cdk-lib module. -
Documentation for constructs in the AWS Construct Library are organized by AWS service in the following format:
aws-cdk-lib.. For example, construct documentation for Amazon Simple Storage Service (Amazon S3), can be found at aws-cdk-lib.aws_s3 module.<service> -
For Constructs library (constructs) documentation, see constructs module.
Contribute to the AWS CDK API reference
The AWS CDK is open-source and we welcome you to contribute. Community contributions positively impact and improve
the AWS CDK. For instructions on contributing specifically to AWS CDK API reference documentation, see Documentation
