Speeding up the JavaScript Ecosystem: Polyfills Gone Rogue? — Marvin has been on a mission to speed up popular libraries – first blogging about speeding up the JS ecosystem, one library at a time last year. Earlier this year he tackled

scripts, and now he’s looking at the role of ‘unnecessary polyfills’ play in making

folders so large. There are two sides to every story, though, as this Hacker News thread dug into.

GitHub Actions Could Be So Much Better — GitHub Actions provides a fantastic and useful service, but the developer experience leaves a lot to be desired, particularly when debugging them.

ASIDES:

• Node’s Fetch API support is going to be marked as stable but some folks have concerns over the move.

• An update on GitHub Actions’ plan to transition from Node 16 to Node 20. “Starting October 23rd, workflows containing actions running on Node 16 will display a warning to alert users about the upcoming migration.”

• Ampt, a spin-off of Serverless Framework, has gone into general availability as a serverless platform for running Node.js and full-stack JavaScript apps.

• It doesn’t officially ‘launch’ till tomorrow.. but a heads up to instant.dev which promises to be an interesting Postgres-focused Ruby on Rails-inspired ORM and migrations system for Node apps.

• ▶️ A fantastic documentary about TypeScript went up on YouTube last week – it covers its full origin story, why Microsoft backed it, and features takes from many folks in the TypeScript and JavaScript space. Entertaining and educational.

🤖 Good news?

GitHub’s CEO, Thomas Dohmke, says that despite the rapid encroachment of AI and ML technologies into the software development sphere, “the demand for software developers will continue to outweigh the supply.” Phew..?

On a related topic, I’m headed to the AI Engineer Summit in a couple of weeks to hopefully get a better feel for whether this is true and just how AI can help us progress as developers without unintended negative side effects. If you’re also going to be there, say hi!
