Code example on how to create an AWS CDK Stack in TypeScript

What is an AWS CDK Stack

A stack represents a bundle of AWS resources contained for a single deployment. AWS CDK Stacks is based upon AWS CloudFormation stacks, therefore it contains the same features and limitations. Synthesizing the AWS CDK Stack generates a CloudFormation template which can be used to deploy on AWS Cloud.

You can define any number of stacks in your AWS CDK app. Any instance of the Stack construct represents a stack, and can be defined directly within the scope of the app. The following code snippet shows how to create an AWS CDK Stack scaffold which you can use as a template to define your stacks.

AWS CDK Stack example

import * as cdk from 'aws-cdk-lib'; import { Construct } from 'constructs'; export interface ExampleStackProps extends cdk.StackProps { //insert properties you wish to expose } export class ExampleStack extends cdk.Stack { constructor(scope: Construct, id: string, props: ExampleStackProps) { super(scope, id, props); //Insert the AWS components you wish to integrate } }


A common pattern when creating a stack within your AWS CDK app is to extend the Stack base class cdk.Stack, as shown in the example. Then you define scope, id and props (interface) that needs to be passed to the cosntructor.

How to use an AWS CDK Stack

Install packages

Install AWS CDK and the AWS CDK v2 library in your project using yarn

yarn add aws-cdk-lib construct yarn add -D aws-cdk

Import the Stack Class

Import the newly created stacks in your CDK App.

import { ExampleStack } from './lib/stack-name';

Instantiate a new stack

After creating the AWS CDK stack class using the templated example above, you can instantiate a new stack in your AWS CDK app using the following code.

import * as cdk from 'aws-cdk-lib'; import { ExampleStack } from './lib/stack-name'; const app = new cdk.App(); new ExampleStack(app, 'newStack', { //insert props which you exposed in the interface `ExampleStackProps` }); app.synth();
