If you’ve built a website, whether for personal or commercial use, you probably researched web hosting options. Lots of companies provide this kind of services. In this post, we will build a very simple website, and host it on Amazon S3 (Amazon storage service), which can be used to host a static website (a site that contains static content and client-side scripts). The interesting part is that ..

The process of doing it = Creat lambda function version: - Default >> no versioning

ASL = Amazon States Language (JSON-based) When I tried to deploy by copying some of the features of yml file (CloudFormation Template), the step function workflow kept failing because CDK is not a level 1 construct where I have to specify everything. CDK performs those parameters or input by itself. I just needed to specify some parts that will be required such as the DynamoDB Table name. Then, ..

import * as cdk from "aws-cdk-lib"; import * as lambda from 'aws-cdk-lib/aws-lambda' import * as sfn from 'aws-cdk-lib/aws-stepfunctions' export default class CdkStack extends cdk.Stack { constructor(scope?: Construct, id?: string, props: StackProps) { super(scope, id, props); // Get the CloudFormation Output value that is already existing in AWS Server with 'Export name' in Output values const ..

Testing Constructs The CDK Developer Guide has a good guide on testing constructs. For this section of the workshop we are going to use the Fine-Grained Assertions and Validation type tests. CDK assert Library We will be using the CDK assertions (aws-cdk-lib/assertions) library throughout this section. The library contains several helper functions for writing unit and integration tests. For this..

To avoid unexpected charges to your account, make sure you clean up your CDK stack. You can either delete the stack through the AWS CloudFormation console or use cdk destroy: cdk destroy You’ll be asked: Are you sure you want to delete: CdkWorkshopStack (y/n)? Hit “y” and you’ll see your stack being destroyed.

cdk diff Before we deploy, let’s take a look at what will happen when we deploy our app (this is just the Resources section of the output): $ cdk diff Resources [+] AWS::IAM::Role ViewHitCounter/Rendered/ServiceRole ViewHitCounterRenderedServiceRole254DB4EA [+] AWS::IAM::Policy ViewHitCounter/Rendered/ServiceRole/DefaultPolicy ViewHitCounterRenderedServiceRoleDefaultPolicy9ADB8C83 [+] AWS::Lambd..

Add a table property to our hit counter Edit hitcounter.ts and modify it as such table is exposed as a public property. import * as cdk from 'aws-cdk-lib'; import * as lambda from 'aws-cdk-lib/aws-lambda'; import * as dynamodb from 'aws-cdk-lib/aws-dynamodb'; import { Construct } from 'constructs'; export interface HitCounterProps { /** the function for which we want to count url hits **/ downst..

cdk-dynamo-table-viewer An AWS CDK construct which exposes a public HTTP endpoint which displays an HTML page with the contents of a DynamoDB table in your stack. SECURITY NOTE: this construct was built for demonstration purposes and using it in production is probably a really bad idea. It exposes the entire contents of a DynamoDB table in your account to the general public. The library is publi..

In this chapter we will import a construct library called cdk-dynamo-table-viewer into our project and install it on our hit counter table.
