Friendly reminder that CommonJS functionality is frequently unspecified and often falls somewhere between "script" and "module" programs as defined by ECMA-262. It's really time to stop using CommonJS.

ESM (ECMAScript Modules, as we all know) is crucial to go to space! Take that, CommonJS.
Artemis II's European Service Module, or ESM, is the crucial ESA component powering #NASA's Orion spacecraft for this mission, its first crewed lunar flyby flight.

Currently working on removing CommonJS support from Iconify packages.
While I did want to keep support for as long as possible, dependencies dropping support for CommonJS make it harder and harder to do. So it is time to join.
Soon I'll release new major versions of all packages, without CommonJS

pnpm init will also default to "type": "module" from v11. Hopefully other package managers will follow pnpm lead. There is no reason to default to commonjs right now.

CommonJS? ESM? TypeScript? Wait, even CommonJS TypeScript?? Eleventy can run them all.

Which should you choose? It depends! The social-media sized answer is: ESM 😅

Now I learned how to convert from CommonJS to ESM.
I've learned how to import functions from different files. 💪
I know it's simple but I've known programming basics for a long time but never knew how to do that so it feels really cool to build out an organized script library
like a sick fuck

i think there’s exceptions to this but they’re very rare, like react betting on commonjs very early (and even then it was alternatively consumable via umd for a loooong time).

just want to come back to this thread to say i still thoroughly disagree with this philosophy of forcing double buy-in with tech looking for mainstream adoption
wanting atproto to win is great
wanting deno to win is cool too
making atproto projects annoying to run outside deno — huge mistake imo

Bundling is such an underused feature of server dev. It can easily reduce cold start times by 30-40%.
Maybe it's because most backend deps are still stuck with commonjs.
