pedalboard VS ESLint

You can check out some demo examples in this Storybook, and see the code in the pedalboard repo.

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.

Also, all the code mentioned here can be found in the GitHub repository for this plugin. Put your testing helmet on, here we go!

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:

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.

For reference, below is an image of the Pagination component, and you can find it’s code here:

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.

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.

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

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!

Let's be honest - setting up tools for a new project can be a frustrating process. Especially when you want to jump straight to coding part. This is often the case with ESLint and Prettier, two popular tools in the JavaScript ecosystem that can sometimes interfere with each other when it comes to code formatting. Fortunately, there's a simple solution to this process, and it's called eslint-plugin-prettier.

Do you have the need to find and fix problems in your JavaScript? Then ESLint is for you. With over 120 million downloads each month, it's definitely one of the most popular projects out there. The latest version introduces a new configuration system, designed to simplify available configuration options. Old and deprecated rules have been removed, and a new configuration inspector has been added. Check out the blog for all the highlights, and a migration guide.

ESLint: A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript.

Automating code checks with static code analysis allows us to enforce code styling effectively. By integrating tools into our workflow, we can identify errors at an early stage, while coding instead of blocking us at the end. For instance, flake8 checks Python code for style and errors, eslint performs similar checks for JavaScript, and prettier automatically formats code to maintain consistency.

If you're a developer, you're surely familiar with Prettier and ESLint. With over 8 years of existence, they have established themselves as references in the JavaScript ecosystem.

eslint is used to avoid code errors

No lint errors: The committed code does not contain any lint errors (eslint).

Let’s walk through the steps for a one-time setup to configure husky pre-commit and pre-push hooks, ESLint with code styles conventions, prettier code formatter, and lint-staged. Husky automatically runs a script on each commit or push. This is useful for linting files to enforce code styles that keeps the entire code base following conventions.
