    Last week, we published 3 security advisories including Brotli, tls certificates, and quic As future hardening, we will replace most of Bun’s C/C++ dependencies with our own safe Rust implementation. Starting with libarchive

    We expect to replace more, excluding WebKit/JavaScriptCore, BoringSSL, and lsquic. There’s still: turbojpeg, libpng, zlib-ng, libdeflate, brotli, zstd, and several more.

    RT @steipete: I spent some time on the weekend to test bun's AOT compiler and results are nothing short of amazing. Performance up 2-3x, memory use less than half.

    Bun AOT also introduces `--trim` which deletes unused parts of Bun from the compiled binary On macOS, a binary that uses Bun.serve’s HTTP server goes from 89 MB to 25 MB

    We published three security advisories for Bun 1.4.3 and earlier: compromised eMudhra certificates, the brotli decoder bug (HTTP2Shell), and the HTTP/3 "Header Accordions" attack. These are all fixed in Bun 1.4.4. Please upgrade, and rebuild anything made with `bun build --compile` $ bun upgrade

    RT @jarredsumner: Merging Bun AOT next week, then testing on Claude Code Expecting 2-3x less memory + CPU & a slightly smaller binary This is the future of server-side JavaScript Instead of you rewriting in Rust, we rewrote JavaScript's compiler to emit native code ahead of time

    4th attempt at Bun AOT. Code quality & design is better. Perf is nearly there. Most importantly though It’s just TypeScript. Disregard everything I said last week about `as` casts changing runtime behavior and function arguments throwing. None of that is necessary.

    We needed to get this release out tonight , so we couldn't include `bun lint` yet. bun lint is available via `bun upgrade --canary` though

    Bun v1.4.4 will be released this evening with a fix for this and for the Brotli issue. Both fetch() and Bun.serve() did not and continue to not enable HTTP/3 by default.

    Sorry everyone... We're announcing a 0-Day vuln in QUIC that allows anyone to remotely turn off a server running these libraries. I swear we didn't plan this.

    bun lint builds on top of: - TypeScript’s parser and type checker, ported to Rust - Lint rules ported from oxlint: unicorn, jest, vitest, jsx-a11y, next and promise - Lint rules ported from ESLint, typescript-eslint, eslint-plugin-react, -import and -react-hooks Big thanks to those projects!
