Claude will likely be bundled up nicely with Bun in the near future. I could see this being useful to let even a beginner use claude code.
Edit:
Lastly, what I meant originally is that most front-end work happens with tools like Node or Bun. At first I was thinking they could use it to speed up generating / pulling JS projects, but it seems more likely Claude Code and bun will have a separate project where they integrate both and make Claude Code take full advantage of Bun itself, and Bun will focus on tight coupling to ensure Claude Code is optimally running.
Frontend work by definitions n doesn’t happen with either Node nor Bun. Some frontend tooling might be using a JS runtime but the value add of that is minimal and a lot of JS tooling is actually being rewritten in Rust for performance anyway.
