Installing node_modules is a great time for a coffee break. Don't take this away from me! Otherwise I'll have to go back C++.

[@F1nnyF6]

With C++ you can just have a coffee break when it's compiling instead

@@F1nnyF6 Incorrect. C++ is very very fast in terms of compilation and caches everything. Rust is the one that's fucking slow as hell; probably the only thing I hate about Rust is compliation time, which is the worst out of every language in existence.

[@shelterit]

$ is not Bash spawned in Bun, it's its own minimal semi-compatible Bash-like language that deals with the core of stuff we normally do in CD, and you can pipe stuff hither and dither into JS buffers. But it's NOT Bash, just a lexar and interpreter back into the Bun JS runtime (so any bug-fixes or improvements to Bun also applies to this process), so any tools that works checking JS code can check this. It's really good for offloading a lot of multi-OS scripting into a simpler platform. I use it for a lot of infrastructure stuff, I hate Bash / Ash cross-platform nonsense with a passion.

[@havocthehobbit]

people complain when devs dont give short concise updates instead of just throwing out mounds of documentation , then people complain when they do and point out ambiguity as if the info should have been a 1 hour video that few would have watched to beyond half way. The poor fellas appear to have tried and got out of there comfort zones , so I appreciate this even tho I probably wont adopt bun until new project just like I havnt adopted deno yet.

[@sigmundwong2489]

regarding that rm -rf business at around 6:10... Git for Windows distributes a copy of bash and a bunch of common userland tools... am I missing something, or is there a reason not to use them?

I will never diss on optimizations in software used by many devs. A lot of this may seem inconsequential, but if you've ever worked with a compiler like tcc you'd know how good it feels to compile and run a large project in < 50ms Entire problem sets disappear when you can just do the naive thing and have it be realtime

The dev's might only do "Bun install" once, the CI/CD does it all the time, that 18X improvement will increase your actual velocity when working on large scale project with deployment pipelines.

[@laztheripper]

Last version got me excited to try Bun, to migrate some of my stuff, but quickly found out it didn't run directly on Windows. So this release made me migrate my website to Bun. Unfortunately, I have to say I did not see an improvement in performance. It was ~20% slower than node running "vite build" and "vite dev". Long running functions ran ~20-30% slower. Startup was slightly faster, and so was install, but I really don't care about the performance of my site when it's not even handling requests yet. So I did a little search and found out it's just that JSC optimizes less (faster starts) but runs slightly slower afterwards compared to V8. That said, I still plan on keeping Bun around for package management and the handy one liner to create an .exe from your JS/TS code.

[@martijn3151]

19:00 just because different languages compile to an intermediate language, doesn’t necessarily mean the resulting output is comparable in terms of performance. The resulting intermediate code will be different for each language and will be compiled into actual bytecode. And it’s obviously not guaranteed that that last step will always result in identical performing bytecode, given different inputs.

[@javiasilis]

@14:18 I used to wait 182 seconds for my react project to cold start when I was using webpack (260K LOC) w/TypeScript. That and the fact that I had barrelled all the exports within Create-React-App because there was no path aliases made it a nightmare. I saw glory when I migrated it out to Vite. Cold Start - 28seconds. Cached, it would boot up in 4 - 5 seconds. It was important when you messed up with tsc and it had to restart to pickup the changes.

My Last two bosses had that mindset. Hurray for windows finally getting a usable shell scripting language, that does not require setting up an entire virtual machine. 5:50 : (Just try the command 😏) The command runs fine. It is just a shame, that such a video came out on April 1st. The only day of the year when people question if what they read on the Internet is true. Some of it sounds clearly like BS though, especially some of the Performance stuff. 9:33: (Who uses the same scripts on Mac, Win. and Linux?) That would be me. I'm forced to run Windows at work. I have to use MacOS for debugging PWAs on iPads. I Run Linux at home. Having the same helperscrips just work everywhere sounds amazing.

Windows is the best desktop OS, it's not perfect, but takes next to no effort to get it to be B+ while sure, you can master your Linux install to get it to an A+ but at what cost? that being said: if you have to develop directly on host RUN AWAY we have WSL and full fledged VM's for a reason also powershell is a better scripting language than bash, it saves you from so many string manipulations! but yeah, it's not great either, just slightly less broken

24:40 if I see more than 10 dependencies in something I import in any sane language, it's getting uninstalled.

[@jancartman321]

Same. It's clearly the devs choice and not necessarily the language's fault. You can create a Go project with 100 deps or with just one (postgres driver, e.g. pgx). The same is true for Node. It has everything you need for the basic server except for the postgres driver (postgres.js has no additional deps). When Prime is talking about 100 deps for a web service, then it's not Node's fault but the fault of the sloppy devs who include every piece of crap from NPM. Rust is a different story, as the std lib is not as comprehensive as Go's or Node's. Listing all deps for a basic Axum and postgres backend is a bit disturbing.

[@Sancarn]

9:42 Well you do work primarily at Netflix, so are going to be using primarily web-server technologies. Most web-servers are linux only. If you work in desktop applications, this is way more common. 10:24 Yes. Cross-platform desktop applications are a maintenance nightmare. But stuff like this is a step towards making it less of a maintenance nightmare imo.

@29:00 you don't need to build trust, you need to build VC moneyz!

[@bluegreenbugs]

There is one things between language. They can be more expressive on type and memory access pattern that are reflected in the intermediate language. So even if all language end up using LLVM, they can have different performance outcome. A very excessive example in that regard would be to compare ISPC vs C++ both using LLVM. As ISPC express data parallelism, LLVM can generate SIMD code by default and so the code generated when using ISPC will be faster than a C++ code that just use C++. Same things happen with rust, as it express more information memory access and ownership, the generated IR has more information and LLVM can generate better binary at the end. My understanding is that zig is also better than C++ at expressing this memory ownership and data parallelism problem, so even with a LLVM backend, zig could be better than C++.

Mocking is not "tsting your feelings". Mocking allows you to test against the agreed upon design contract. I mean, I know that Primeagen trolls all the way, but people do pay attention to what he says. So once again, good mocking is an excellent addition to a testing suite: implement standard (as pre-determined by the agreed design documentation) expectations in mocks and then test to your heart's content.

[@jful]

I personally am not a fan of mocking, I do use it sometimes but prefer fakes at the service boundaries where possible. Code bases where I have seen extensive use of mocks have had very brittle tests that make refactoring difficult and do not give a high level of confidence that the system as a whole is working. Maybe this is just an issue with overuse of mocks though. Like I mentioned personally I use mocks sometimes but try to do it as little as possible.

[@ollegio]

Was it really such a necessary feature to use shell scripts on windows? Must have been a lot of work translating each bash command to a windows counterpart. And there will always be some small differences, like different versions of bash, which have different arguments for commands. All that work when there is already a decent solution - wsl lol

[@Z4KIUS]

Bun is in that weird place of performance where it isn't exactly great at edge as it still starts up pretty slowly when compared to edge solutions but once it does it runs so much faster... there's probably a right use for that, but I wouldn't put it on rarely run on demand environments just yet

[@jimshorts4317]

If, as a developer, you are installing node_modules 3 times a day, there is something massively wrong with what you are doing or what you are working on. In enterprise, on any existing web application, you are installing node_modules (via npm, yarn, whatever...) once. Maybe a second time SIX MONTHS later. What is wrong with all of you people?! The only thing that this matters for is operationalization. Building environments on the fly. Which, yes, you should have all your dependencies cached and the build server reaches into the cache (which is ideally on the same server) to pull those. This is why `npm ci` exists. Use the package-lock, pull those dependencies from cache, install them. Should be fast. Needs to be as fast as possible, especially if you're building ephemeral environments for test teams constantly.

[@gryg666]

With this pace, Bun 2.0 will be standalone OS ;)

I don't disagree but how do you define runtime?

[@remrevo3944]

​@@JannisAdmekI don't have a good *complete* definition, but things like Rusts panic unwinding, or C++'s exceptions definitely are runtime things. Also I think that C might set up some default signal handler. Also C's default IO-buffering might count under runtime. (Also there is something like "life before main".)

[@eslachance]

The thing that makes me not be able to use bun as a node drop-in replacement is that they don't support node-gyp dependency building and they don't automatically insert their bun-specific dependency in imports. *specific actual example*, I have a wrapper around better-sqlite3 with 5+ million views. This wrapper cannot be used in bun because better-sqlite3 isn't buildable in bun, and I'd have to make a branch/more code/environment checker, to change the *import* I'm using in order for my module to be useable in bun. Just to save 30 nanoseconds to run tsc --help, I guess?
