I work on Bun. Happy to answer any questions.
Batteries included is the way to go. I hope the battery gets larger and larger and you also keep up the quality.
- extremely happy bun user
It's for the same reasons that I switched to biome. It's faster and reduces total dependencies. I very happy with this combo.
Is there more code tooling (linting, formatting, etc.) on the roadmap for bun, or are you focusing on the runtime features?
If you're worried about binary size from features you don't use: the binary size cost of Bun.sql is less than 50 KB (you can check this yourself via the .linker-map file in the *-profile.zip builds of Bun or via https://bloaty-csv-reader.vercel.app which was a tool I wrote a little while ago to see how much space various features of Bun use)
If you're worried about runtime overhead, practically everything in Bun is lazily loaded. So if you never access Bun.sql or Bun.S3Client, it will not load it. And, even if it does load it, because we implement it in native code and worry about this a lot, it doesn't really cost much to load.
I don't know about all the reasons, but personally I stay away from projects who try to bundle in as much functionality as possible into one "all-in-one" thing. I prefer approaches where you yourself chose the right library for the problem at hand, as it tends to be that different libraries have different tradeoffs, and I want to chose those tradeoffs myself. Summarized as The Unix Philosophy or "do one thing and do it well" I suppose.
I'm not saying it's wrong of Bun to include those things, their value proposition is the "all-in-one" approach, which a large group of people seem to like, so seems they're doing right by their audience.
But again, personally I don't like the tradeoffs involved with that approach, but I wouldn't try to convince Bun either to go against their explicit goals.
And like diggan said here, I like tools with focus, for example I choose to use one note taking app, one separate app to write code in, another app to chat with, and yet more apps for things like email, and SSH even though they are all text-centric apps and could be bundled into one and the same.
