You can use it today with containers in Lambda or a custom Lambda runtime, but both approaches have embarrassingly slow cold start. Lambda has special optimizations for Node which are not possible without official support. I have no idea wh

(I work on Bun) A neat thing about tail calls in JavaScriptCore: there’s an explicit bytecode intrinsic for it. return @tailCallForwardArguments(MyConstructor, this); To use this in Bun, you’d have to start Bun with the environment

One of the optimizations we do in Bun.build() is to automatically rewrite imports/requires of CommonJS modules shaped like this if (process.env.NODE_ENV === "development") { module.exports = require("./a

I work on Bun Fastify is not fast in Bun. Bun.serve() is 3x - 4x faster. Our node:http code currently just wraps Bun.serve(). node:http has to go through many extra string -> buffer conversions and microticks and does a lot of unnecessar

Sorry about this. You can join the help/help-chat in Bun’s discord to get help and that is more organized

What issues are you running into? We added support for setRawMode in Bun v0.8 (a month ago) and that addressed many issues with stdin and readline.

That throws since we cannot make it synchronous. It works by reading the internal state of the Promise and getting the value out of it if the Promise is fulfilled.

bun repl was a last-minute hack we added. All it does is "bun x bun-repl" which is currently not an official thing. The repl is about to be added and rewritten completely

This might work now. It didn't in v0.5.x and earlier. We added proper CommonJS support and that means sloppy-mode features that Node-RED relies on should work just fine.

In Bun, you can use import and require in the same file. There's three steps for what makes this work: 1) We patched JavaScriptCore to load ES Modules synchronously when they don't use top-level await. The main tradeoff here is th

We originally planned to release yesterday, but there were test failures in fetch() body streaming that needed to be fixed. The blog post was not meant to be public until Bun 1.0 was available on GitHub, but the blog post link was publicly

We haven't added support for emitDecoratorMetadata yet but we have a branch that does most of the work. It just needs some more tests before we're comfortable merging it

Remix in Bun works on Linux. The built version also works on macOS, but the dev version is blocked on us upgrading WebKit. Intl.ListFormat which Remix uses depends on a newer version of ICU which the current version of WebKit uses but we di

Bun uses Zig’s standard library carefully. We read the code for the parts we use (and sometimes change it locally). We also rely on mature C/C++ libraries like picohttpparser, BoringSSL, c-ares (along with the C std lib). We use lots o

Yes it would be possible, though it'd be easier to start in Bun and then call out to your executable from JavaScript via napi or bun:ffi

This definitely also used to be true on macOS. Bun previously would just request the max ulimit for file descriptors and then not close them. Most tools don't realize there are hard and soft limits to file descriptors, and the hard lim

The honest answer is: don't know yet, but if it doesn't happen in 1.0, it will be the priority for 1.1. I'm going to do some experiments in the next few days and see how it goes. Roughly, the way we're thinking of adding
