Bun is getting a lot of hype due to all the press, but almost everyone is just echoing Bun's docs and marketing material and lack direct experience using it. I haven't done a deep dive into Bun yet, but I have tried porting a legacy project to it. Hit a lot of issues after a few hours of hacking around. It wouldn't correctly install node modules because of opt-in dependency lifecycles (and maybe other issues?) and then I couldn't use it to execute the existing webpack build without encountering opaque runtime errors.
The promise of Bun seems pretty good, but I think their marketing material is further along than their core projects atm.

There was discussion about this the other day. It's marketed as a "drop-in" replacement but from perusing HN and elsewhere I see people having issues with real projects. It looks like a promising project, which I hope succeeds, but there also seems to be an unfortunate amount of marketing that, as you note, is being uncritically repeated.
I think running a bundler on top of bun defeats half of the purpose of the tool, unfortunately bun's own bundler is still very lackluster and definitely not good enough to use. On top of that most of the popular frontend frameworks (Vite, NextJS, etc) are doing their own bundling so I wouldn't use bun with those tools either.
I would consider it only for backend nodejs at the moment.
I think people are surprised that the performance claims don’t completely disappear with real world scenarios. It seems like a lot of eventually successful platforms began in the same way: the claims about improvements are real, and there are still a lot of rough edges.
It seems like it has potential but I tried using it with a Shopify app I am building and for some reason it wasn't automatically creating the cloudflare tunnel in dev mode. Also, there's no verbose flag to show more detailed log message.
