The AWS Cloud Development Kit (AWS CDK) is an open-source software development framework to define cloud infrastructure in code and provision it through AWS CloudFormation.

The AWS CDK consists of two main components:

• a class library, that you use to to model your infrastructure in code; and
• a toolkit, consisting of a CLI or a programmatic library, to act on those models.

This repository contains the code for the toolkit components. The class library repository is the main repository for the CDK project.

The best way to interact with our team is through GitHub, on the aws-cdk repository. You can open an issue and choose from one of our templates for bug reports, feature requests, documentation issues, or guidance.

If you have a support plan with AWS Support, you can also create a new support case.

You may also find help on these community resources:

• Look through the API Reference or Developer Guide
• The #aws-cdk Slack channel in cdk.dev
• Ask a question on Stack Overflow and tag it with aws-cdk

We welcome community contributions and pull requests. See CONTRIBUTING.md for information on how to set up a development environment and submit code.

Here are the packages in this repository. See the README of each package for more information about it:

Package	Description	Published?	Maintained?
aws-cdk	The CDK Toolkit CLI, main CLI interface to CDK projects.	Yes	Yes
@aws-cdk/toolkit-lib	A programmatic interface for the CDK Toolkit.	Yes	Yes
cdk	An alias for aws-cdk so you can run npx cdk even if it's not installed.	Yes	Yes
cdk-assets v3	CLI component handling asset uploads, also used as a CLI in CDK Pipelines	Yes	Yes
@aws-cdk/cloud-assembly-schema	The contract between the CDK construct library and the CDK toolkit	Yes	Yes
@aws-cdk/cloudformation-diff	CLI component for diffing CloudFormation templates	Yes	Yes
@aws-cdk/cli-plugin-contract	TypeScript types for CLI plugins.	Yes	Yes
@aws-cdk/cdk-cli-wrapper	A deprecated attempt at building a programmatic interface for the CLI	No	No
@aws-cdk/node-bundle	A tool to build CLI bundles that include license attributions.	No	Yes
@aws-cdk/user-input-gen	A build tool for the CLI and toolkit-lib.	No	Yes
@aws-cdk/yarn-cling	A deprecated build tool for the CLI.	No	No

Every package comes with its own unit tests. There is a companion repository to this one containing the integration tests. You can find it here: https://github.com/aws/aws-cdk-cli-testing

See the contributing guide for more information on this repository.

The CLI is always able to process CDK apps using a version of the Construct Library released before it. We recommend you always keep the CLI version up-to-date to get the latest features.
