Angular Testing in 2023 - Past, Present and Future
In a future release, Angular will replace Karma with the web-test-runner from ModernWeb. That future release might already be Angular 17. ModernWeb is a modern community project that embeds tests into a browser.

Testing Web Components with @web/test-runner
So, you write web components and you're interested in expanding the work you put into unit testing them? Well, you've come to the right place. This is just the beginning, but Testing Web Components: the Series is going to lay out for you how Open Web Components and Modern Web help you to do just that. We'll start with how the Open Web Components generator can get you up and running in no time with @web/test/runner right out of the box.

If you're writing in Markdown, I recommend Rocket, an SSG that uses WebComponents!
Rocket is an SSG that allows seamless integration of Markdown and WebComponents. There is a project to support the development of web standard technologies called Modern Web, and rocket is a subproject of that project. Other sub-projects are test runner and development server, modern-web for development server, and open-wc for WebComponents development, testing, and linter.

Building apps in minutes, not months
Just setting up a front end dev environment is a lesson in complexity theory
FWIW, because I've been out of web dev for a while and may need to get back into it, I came across this site today:
https://modern-web.dev/
I followed their example ts+preact+esbuild setup and was very pleasantly surprised by the ergonomics.
I was expecting way worse.

The best testing strategies for frontends
With the advent of tools like Puppeteer and now Playwright, end-to-end testing has become much easier and more reliable. For anyone who's used Selenium in the past, you know what I'm talking about. Puppeteer has opened the way in terms of E2E tooling, but Playwright has taken it to the next level and made it easier to await for certain selectors or conditions to be fulfilled (via locators), thus making tests more reliable and less flaky. Also, it's a game changer that it introduced a test-runner - this made the integration between the headless browser and the actual test code much smoother.

HTML to PDF renderers: A simple comparison
HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.

How to build a WhatsApp AI assistant
This library works by creating an instance of WhatsApp web running inside an instance of headless chrome automated by puppeteer. In my testing, I ran into tons of compatibility issues when trying to use these dependencies inside anything other than a bare-bones Node.js + express server. Also, we can’t spin up a new instance of chrome and WhatsApp web each time a user sends a message, this will exhaust our allowed WhatsApp connections (4 max), not to mention that doing this will make the response times painfully slow.
