What is the AWS CDK ​

The AWS Cloud Development Kit (CDK) is a framework for defining cloud infrastructure as code and provisioning it through AWS CloudFormation. Instead of writing YAML or JSON templates by hand, you write ordinary code, in TypeScript, Python, Java, C#, or Go, and the CDK synthesizes it into a CloudFormation template behind the scenes. This site documents every construct, class, interface, and enum available for that code: what it does, what it takes, and how it fits together, with a working example on every page.

Getting started ​

New to the CDK? The Getting Started guide walks you through installing the CDK CLI, creating your first app in any of the five supported languages (TypeScript, Python, Java, C#, or Go), and deploying it. The CDK Workshop is a longer, hands on tutorial if you want to build something real before diving into the reference.

Once your project is set up, use this site as your reference: every construct, class, interface, and enum has a working example on its page, shown in whichever language you pick with the navbar's language switcher.

Already comfortable with the CDK? Jump straight to the API Reference or use the search bar to find the construct you need.
