I was scrolling through the Bun blog this morning and saw the announcement for Bun v1.3.14. For a developer who spends a lot of time juggling Node, Deno, and now Bun for server‑side JavaScript, every new release is a chance to cut friction. This one is interesting for three reasons:
Bun.Image – a brand‑new, built‑in image processing API that promises to replace external libraries like sharp or jimp.
7× faster warm installs thanks to the isolated linker's global store – a real win for CI pipelines that spin containers up on every commit.
Experimental HTTP/2 and HTTP/3 support for the fetch API – finally a way to get modern multiplexed connections without pulling in a separate client.
Below I walk through what the new API looks like, how to enable the experimental fetch client, and whether the upgrade is worth the switch for a typical web service.
