This documentation is for the developer preview release (public beta) of the AWS Cloud Development Kit (AWS CDK). Releases might lack important features and might have future breaking changes.

Multi-Language Support in the AWS CDK

This section describes the multi-language support in the AWS CDK, including hints for porting TypeScript to one of the supported languages. See Hello World Tutorial for an example of creating a AWS CDK app in a supported language.

The AWS CDK supports C#, Java, JavaScript, and TypeScript. Since the AWS CDK is developed in TypeScript, many code examples are still only available in TypeScript. This section will help you port those TypeScript examples to one of the other programming languages.

Importing a Package

In TypeScript, you import a package as follows (we'll use Amazon S3 for our examples):

import s3 = require("@aws-cdk/aws-s3");

C#JavaJavaScriptPython

C#

using Amazon.CDK.AWS.S3;

Java

import software.amazon.awscdk.services.s3.*;

JavaScript

const s3 = require('@aws-cdk/aws-s3');

Python

from aws_cdk import aws_s3 as s3

Creating a New Object

In TypeScript, you create a new object as follows. The first argument, scope, is always this, the second is the id of the construct, and the last is a list of properties, often optional.

new s3.Bucket(this, 'MyFirstBucket', {
  // options
});

C#JavaJavaScriptPython

C#

new Bucket(this, "MyFirstBucket", new BucketProps
{
  // options
});

Java

new Bucket(this, "MyFirstBucket", BucketProps.builder()
  // options
}

JavaScript

new s3.Bucket(this, 'MyFirstBucket', {
  // options
});

Python

s3.Bucket(self, 
  "MyFirstBucket", 
  # options,)
