00:00:40>> Okie doke, hi, everybody.
00:00:51Second time in a row that I made it to the stream.
00:00:56Plan is to stream more or less every Thursday.
00:01:00I had a long break, but last week I streamed, this week I streamed super happy to be back.
00:01:07And yeah, the topic for today is really just, for one, do some chatting, questions, whatever.
00:01:16But I also picked something which I found quite interesting, and that is BUN's evolution.
00:01:23Because BUN, of course, whoops, I already got it here.
00:01:26BUN, of course, is that JavaScript runtime, that alternative to Node.js.
00:01:32Yeah, hi everybody who's coming in.
00:01:35Great to have you here.
00:01:36Welcome to the stream.
00:01:38So BUN, of course, is that runtime, that alternative to Node.js, alternative to Dino.
00:01:45And I found it quite interesting to see what happened to BUN over the last year,
00:01:54or the last years, but mostly the last year, or actually really just the last months, I guess.
00:02:00And I thought, yeah, that might be worth diving a bit into.
00:02:04And then maybe later, not sure yet, maybe we can also take a look at Adonis.js,
00:02:08which is a JavaScript framework, or a TypeScript framework, I guess,
00:02:13which is essentially Laravel for JavaScript.
00:02:19And I've heard about Adonis many, many years ago already,
00:02:24because actually I did some research, because I started my career.
00:02:30You're skipping university lecture for streaming, oh, that's too kind.
00:02:37I hope you don't get into trouble over that.
00:02:40Yeah, I started my career, or not my career, but I used a lot of Laravel over 10 years ago.
00:02:46And then I did some research.
00:02:48Hey, is there actually a Laravel for JavaScript?
00:02:52And I found Adonis.js, and play is an interesting post here,
00:02:57that BUN may be moving to Rust, though it's just an experiment for now,
00:03:01to Rust, though it's just an experiment for now, but still pretty interesting.
00:03:08Am I offline?
00:03:11Why is it showing me that I'm offline?
00:03:22No, I'm online, I guess, hopefully.
00:03:37Okay, so yeah, what's interesting about BUN is a couple of things.
00:03:42First and foremost, they have been acquired by Anthropic in December last year.
00:03:49Anthropic acquires BUN, and the reason for that, or one of the reasons is,
00:03:54that Clot code is actually a BUN application, because BUN, this runtime, has a feature
00:04:03where you can compile a JavaScript program in the end,
00:04:14a BUN-powered JavaScript program into a standalone executable.
00:04:19Is it this one here?
00:04:22Yeah, it is.
00:04:23No, this one, single file executable, that's what I mean.
00:04:33So you can actually use BUN to compile some TypeScript code into a self-contained executable,
00:04:44which you can then share with other people who don't need to have BUN on their systems,
00:04:47which is of course pretty convenient.
00:04:49And Clot code is such a single file executable in the end.
00:04:54Clot code is a TypeScript application built with BUN
00:04:59and then compiled with BUN to such a single file executable.
00:05:03So that is probably one of the main reasons why Anthropic acquired BUN.
00:05:07Also, maybe, because BUN was a venture capital-backed project or company,
00:05:17and is the picture frozen?
00:05:21I had a temporary glitch, I think.
00:05:24The internet was off temporarily, but I hope I'm back.
00:05:27Or am I still frozen?
00:05:28Let me check again.
00:05:31I thought I was online again.
00:05:33Connection poor.
00:05:39Unfortunately, there is little I can do here.
00:05:46Can you?
00:05:47Video is lagging for me as well.
00:05:49Well, that is not good.
00:05:51Why am I having these problems?
00:05:53Unfortunately, I have no quick way of fixing this.
00:05:58Frozen for me as well.
00:06:12Why is that so bad?
00:06:20Is there something on my network?
00:06:26I'm in a shared office here, so I have limited control over the network, unfortunately.
00:06:32Interestingly enough, it's showing me that everything is good here in my streaming software.
00:06:42I could vibe code YouTube in five minutes with Claude.
00:06:53I honestly can't just hope that it gets better, because I can't switch to a cable or anything.
00:07:12I mean, I can restart the stream.

Key Takeaway

Anthropic's acquisition of Bun highlights the runtime's utility in building and distributing standalone TypeScript applications like Claude Code through single-file executables.

Highlights

  • Anthropic acquired Bun, the JavaScript runtime and Node.js alternative, in December 2025.

  • Claude Code functions as a Bun application, leveraging Bun's ability to compile TypeScript into standalone executables.

  • Bun enables the creation of single-file executables that run on systems without the Bun runtime installed.

  • The Bun development team is currently experimenting with a potential migration of the runtime to the Rust programming language.

  • Adonis.js serves as a TypeScript-based framework designed to provide a Laravel-like development experience for the JavaScript ecosystem.

Timeline

Bun Runtime Evolution and Anthropic Acquisition

  • Anthropic finalized the acquisition of Bun in December 2025.
  • Claude Code is a TypeScript application built and compiled using the Bun runtime.
  • Bun transforms TypeScript code into self-contained, single-file executables for simplified distribution.

The acquisition follows Bun's established role as a high-performance alternative to Node.js and Deno. A primary driver for this move is the technical architecture of Claude Code, which relies on Bun's compilation features. These features allow developers to share applications with users who do not have the Bun runtime pre-installed on their local machines.

Rust Experiments and Full-Stack Framework Alternatives

  • Technical experiments are underway to explore moving the Bun codebase to Rust.
  • Adonis.js provides a structured, Laravel-inspired environment for JavaScript and TypeScript developers.

Ongoing development efforts include exploring Rust as a potential foundational language for the runtime, though this remains in an experimental phase. For developers seeking a full-stack experience similar to PHP's Laravel, Adonis.js remains a prominent framework choice. Network connectivity issues in the shared office environment eventually interrupted the technical deep dive into these tools.
