A set of "blessed" known good packages would be wonderful to have in any language, I wonder why it's not a thing.
It has just been a pretty low effort drop in replacement for me. It's definitely not a complete game changer, but quick iteration is just that bit more convenient since it's faster and I don't need to remember all the flags I normally have for my setup (Typescript, .env file, etc...)
Of the "batteries included" features, the `Bun.serve` web server and the `HTMLRewriter` HTML5 SAX API thing are very powerful, saving a lot of node_modules space.
Running TypeScript without a build step is neat. (I know there's `node --experimental-transform-types`, and it's great to see this feature propagated "upstream")
That said, for large established Node.js projects, I don't really see the pull to switch over to Bun. There's cost associated with it (for one, the built-in test runner works a bit differently, so if you're using `node --test` it'll require some fiddling)
They can easily provide official extensions/packages clearly namespaced and avoid all this mess. But I fear that they're more focused on a "headline-driven-development" approach, the more different from the status quo, the better
