A year from now folks will be; I can’t use it anymore it’s too unreliable but for now keep looking the other way.
Yes, I know there's probably better options than Rust for building APIs, but I wanted to learn it, so why not?
How is this even possible?
I know we're all using AI, but Bun seems like the one singular project where there's just been a crazy increase in the amount of output, a 10x on the 10x.
How are they doing this?

Why would I want everything reimplemented in this massive binary? Why would Bun be anymore in touch with nuances of all these different technologies then individual projects dedicated to their own speciality?
JS Runtime, Package Manager, Test Runner (both unit and headless browser), Bundler, JSX, PosgreSQL/MySQL/SQLite drivers, S3 client, Redis client, Formatter, Linter, etc.
Not to mention parsers for YAML, TOML, Markdown which are easily three separate projects worth of complexity in their own right.
I guess one clear downside is to get all these great features they're pushing for 1.4 you needed to wait until everything was ready. Given 1.3 was pushed out in October 2025, a 10 month release cycle across so many large technologies is tough. Before you give a pass because of the Rust rewrite Bun 1.2 was released in January 2025

But now that Bun is actually doing it its somehow bad? Its also still open source, so those implementations you mention need dedicated teams can still get the attention they need by the community if needed.
I'm on the side that I'd actually prefer if node included more out of the box and we could drastically cut down on the number of packages we need due to the amount of supply chain attacks that happen on packages in the node ecosystem.

Otoh should a standard lib give you absolutely everything? Probably not. There needs to be a line somewhere.
Right now Bun’s policy on this seems to be "whatever Jarred feels like should be in there".

This is the main draw. Everything he implemented was fast and minimalist and he usually implements a standardized api (web apis, esbuild bundler api).
The opinionated stuff is usually very common sense.
Most of the libraries OC mentions are things you would just like to be as fast as possible above all else.

I feel like nobody complained that you needed to install a dependency to do headless browser testing for example.

You have more options, not less, you can still use the external dependencies.

It's funny because the top article on HN is about a malicious rust crate package, and people keep making comparisons to js/npm and how both language suffer from frequent security issues because they have weak std libs.
