Get Your TypeScript Coverage Report
Turns out there are tools for that and one of them is called typescript-coverage-report by Alex Canessa and I’m going to give it a try now and implement it in my Pedalboard monorepo.

Supporting SASS in your TS React project using TSC and esbuild
My Components package currently supports regular plain-old CSS (not that there’s anything wrong with it), and I thought it was a good time to introduce SASS to it, but the package is not a ordinary “Webpack-build-that-s#!t-for-me”. I’m using TSC (TypeScript Compiler) to generate the artifacts - What it means is that TSC is compiling 2 versions of the component, ESM and CJS. Once we have these, we’re taking the ESM outcome and bundling it using esbuild. You can read more about it here, but if to put it visually:

Testing Your Stylelint Plugin
In this post I will write a test suite for my @pedalboard/stylelint-plugin-craftsmanlint. We will be using jest-preset-stylelint to help us with that, and as a bonus, I’ll fortify the plugin’s TypeScript support.

Visual Testing Your Components With Chromatic
Disclaimer - I’m going to apply the following steps on my Pedalboard monorepo. Working with monrepos is a bit different, and I will relate to that during the process, but be aware that applying Chromatic on a “simple” repo is even simpler.
-
Introducing esbuild To Your Monorepo
I have noticed that although the build process for packages under my “pedalboard” Monorepo creates different artifacts (CJS, ESM and types - you can read about it in more details in my “Hybrid NPM package through TypeScript Compiler (TSC)” post) it does not create a single bundle for the entire package.

Visual Regression Testing with Cypress 10
I will attempt to introduce this visual regression testing to my Pagination component from the @pedalboard/components package. So here we go.

Giving Jest-Preview a Spin
So let’s see how this tool works and what we can do with it. I’m gonna do my experimenting over my Pagination component which resides on the @pedalboard/components package. Let’s go!

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.
