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.
