An Overview of Node’s Architecture, Event Loop, and More — We’re were starting to suspect that the good doctor (also the author of books like Deep JavaScript) was working on a Node book and.. he is: “Writing cross-platform shell scripts with Node.js.” Happily, we get to enjoy the byproducts of his work like this succinct, yet technical, overview of Node’s key elements.

🤖  Rewriting Tests from Cypress to Playwright with AI — Gajus needed to move an entire integration test suite from one framework to another – boring and laborious job, right? Gajus put AI to work, first in the shape of GitHub’s Copilot, but then using OpenAI’s GPT3 model directly. It sorta worked, but I can’t help but feel that then your tests might need their own tests… 😆

npm-check-updates: Update

Dependencies to Latest Versions — That is, as opposed to the specified versions. A particularly neat feature is the

interactive mode so you can look at potential upgrades and then action them one by one. (Thanks to Sam Selikoff for reminding us of this tool.)
