sls-test-tools VS aws-cdk

Creating an EventBridge target to dump events to SQS. This approach was proposed in several articles (here and here) and implemented in the sls-test-tools library

How can you achieve that? 🤔 Using sls-test-tools 🏅

Check out the sls-test-tools as well. It is a great library. I'm using aws-testing-library because I'm used to it.

Integration testing in serverless architectures can be challenging. Testing specific outcomes within managed services is cumbersome. sls-test-tools provides a range of utilities, setup, teardown and assertions to make it easier to write effective and high quality integration tests for Serverless Architectures on AWS.

sls-test-tools

When writing tests using something like aws-testing-library or sls-test-tools, we must have credentials to an AWS account that at least lets us send a few events and subscribe to or query the results in order to perform assertions. Depending on the stance of our organization about cloud access, this could be completely fine or it could be a never-gonna-happen dealbreaker. Often this kind of approach will be OK for a development environment, but it could be unlikely to fly in production.

https://github.com/aws/aws-cdk#at-a-glance is the "generate cloudformation using code," and is the AWS version of troposphere as best I can tell

environment: Specifies the environment variable that will be available to our Lambda function. In this case I wrote an environment for RDS Database. Anyway, later I will write about AWS CDK using Python for creating database clusters, etc.

Today, I will show you how to build Amazon Location Service, which allows you to build location-based applications within your AWS environment using AWS Cloud Development Kit (AWS CDK) and AWS CloudFormation. I will also show examples of the recently popular CDK Migrate and AWS CloudFormation IaC generator.

AWS Cloud Development Kit (CDK): is an open-source software development framework to define your cloud application resources using familiar programming languages.

I am not one to build programming languages on a whim. In fact, I've spent the last five years building the AWS CDK, which is a multi-language library that addresses some of the challenges I am talking about by allowing developers to define cloud infrastructure using their favorite programming language.

I recently started exploring SST as an alternative to my favorite full-stack set consisting of Projen, AWS CDK, and React. I have been thoroughly impressed with the experience so far. In this article, I will demonstrate how to create a Next.js App Router S3 Picture Uploader using SST.

AWS CDK

For KMS 🔑, Each key is ~$1/mo, and with CDK, keys are generated on a massive scale, if not centralized.

Here is a github repository containing the code and instructions on how to automate this whole setup using AWS CDK.

Now that you have a working smart contract event listener, we'll deploy the resources to AWS using AWS CDK, which is an Infrastructure as Code (IaC) tool. AWS CDK allows you to configure, deploy, and manage AWS cloud resources using popular programming languages such as TypeScript.
