How to Use Bun 1.3.14's Built‑in Image API

Short summary

Bun v1.3.14 introduces Bun.Image, a built-in image processing API that replaces libraries like sharp with chainable transformations and no native bindings. The release also delivers 7x faster warm installs via an isolated linker global store, dropping a 40-package install from ~12s to ~1.7s on CI runners. Experimental HTTP/2 and HTTP/3 support for fetch is available via a bun-specific options flag, with automatic protocol negotiation and connection reuse.

  • Bun.Image offers chainable resize/blur/format conversion with no node-gyp dependencies
  • Warm installs 7x faster via global store caching — major CI pipeline win
  • Experimental HTTP/2 and HTTP/3 fetch support via bun.httpVersion option
