  • ⭐️ Node’s GitHub repo is sitting at 99,803 stars. Can it hit 100k by next week? You know what to do.. 😄

  • 🟩 The two LTS Node.js branches have received releases backporting features from newer versions: Node v20.10.0 (LTS) gains


    and an experimental flag to auto-detect ESM code. Node v18.19.0 (LTS) gets npm 10 and tweaks for customization hooks and loaders.

  • Deno rather than Node, but Deno Cron is an interesting addition to their platform – it’s cron-like scheduling of functions both locally and on their edge/FaaS platform. The integration of language features with their hosting platform has its pros and cons but is interesting nonetheless.

  • We mentioned the release of Mongoose 8.0 (the MongoDB object modelling library) a few weeks ago, but Valeri Karpov now has a post explaining Mongoose 8 in more detail.

  • Node.js performance guru Yagiz Nizipli ▶️ went on the DevTools.fm podcast to talk about Node.js performance and, in particular, his work on the Ada URL parser Node now uses. (There’s ▶️ a video version, if you prefer.)

  • Vercel has announced its deprecation schedule for Node 16. with no new deployments from February 6, 2024.

Pelias: A Modular, Stand-Alone ‘Coarse’ Geocoder — Given an address or place name this will come up with geographic coordinates, and vice versa. In terms of finding a location, it’s not super accurate (hence the ‘coarse’) but it may be acceptable for your use case. Demo here.


⚠️ NPMprune: Prune Unnecessary Files from


— A script that cleans up


by removing ‘unnecessary files’ meeting various patterns. You need to be really careful with this approach, hence the warning icon! The technique is easy to understand at a glance, though, and could perhaps be extended to offer a ‘dry run’ option?
