Building a smart home sensor application with AWS AppSync and AWS Amplify components
This project uses AWS CDK as infrastructure as code solution. To maintain project configuration files efficiently, the project structure is generated using projen:

Project templating cloud
I recommend visiting the github page for projen and flicking through the documentation as I won't do it justice. Projen aims to:

My Infrastructure as Code Rosetta Stone - Deploying the same web application on AWS ECS Fargate with CDK, Terraform and Pulumi
cdk-django uses projen for maintaining the changelog and bumping versions and publishing to npm. It is popular among developers in the CDK community and is a really awesome tool since it basically uses one file (.projenrc.ts) to configure your entire repo, including files like tsconfig.json, package.json, and even GitHub Action workflows. It has a lot of configuration options, but I'm using it in a pretty simple way. It generates a new release and items to the changelog when I manually trigger a GitHub Action.

How to create an AWS Organization for your Account with the AWS CDK
I will give you step-by-step instructions to create your very first AWS Organization with the AWS CDK and the help of projen and cdk-organizations. You only need already an AWS Account created which is not a member or management account of another AWS Organization.

What are some cons of using CDK to create a small part of the platform that is currently deployed by Terraform?
If you go down that route you should use Projen to maintain the dependencies.

Newsletter martinmueller.dev 2022 week 19
An Open Source CDK Community project which I find super interesting. It is doing cherry-picking from AWS Amplify UI and AWS CDK for deployment. I do that in my private projects as well for example https://github.com/senjuns/senjuns. I think the author could enhance/simplify its repo even more by using https://github.com/projen/projen for the project setup.

AWS's Open Source Problem - by Corey Quinn
That said - https://github.com/firecracker-microvm/firecracker and https://github.com/bottlerocket-os/bottlerocket are interesting, and while AWS CDK is very AWS specific, the underlying jsii https://github.com/aws/jsii and projen https://github.com/projen/projen/issues are fundamental services.

How to Create Awesome Repeatable Project Setups for AWS CDK
The documentation for the classes of the bundled project types is at https://github.com/projen/projen/. In this documentation, you can see that the property github includes a mergify entry, which will define if the Mergify configuration is used. The default if the github entry is not specified, is that it will be included. So in our test, we can check that this configuration is not in place, after creating a project with the mandatory parameters.

How to Add Firebase Authentication To Your NodeJS App
There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

JS Toolbox 2024: Bundlers and Test Frameworks
Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Painless CLI integration testing
We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

What is integration testing in UI/Front End?
Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.
