Earlier this year he [tackled `npm` scripts](https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-4/), and now he’s looking at the role of ‘unnecessary polyfills’ play in making `node_modules` folders so large. There are two sides to every story, though, as [this Hacker News thread dug into](https://news.ycombinator.com/item?id=37604373). Marvin Hagemeister [GitHub Actions Could Be So Much Better](https://blog.yossarian.net/2023/09/22/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.

Taro Dragan _ASIDES:_ - Node's Fetch API support is [going to be marked as stable](https://github.com/nodejs/node/commit/740ca5423aabc06af48f6dacfb17335bbaa25c0c) but [some folks have concerns](https://github.com/nodejs/undici/issues/1737#issuecomment-1729783598) over the move. - An update on [GitHub Actions' plan to transition from Node 16 to Node 20.](https://github.blog/changelog/2023-09-22-github-actions-transitioning-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](https://getampt.com/), 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](https://www.npmjs.com/package/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](https://www.youtube.com/watch?v=U6s2pdxebSo) 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.
