Ya'know I still watch so many coding/tech news channels even though I left the programmer life 4 years ago to become a blue collar welder for a simpler calmer life. The landscape was so crazy for web dev 2015-2021 (really since its been a thing) that I thought I'd leave for a while and come back once things are figured out a bit. Maybe it might be a good time to throw my hat back in the ring and make some side projects for fun on the weekends. These new tools that come out actually look they are fun to use. :D

Let me tell you it is the most productive and most fun I've had writing server side Typescript code in a very long time. No more slow tsc builds, no having 2 terminals open with tsc watch and node. It just works, it's fast as hell and it's so much fun to work with. I never felt like Deno could fully replace Node but Bun probably could for me.

I really want to be optimistic for Bun, however they were fixing breaking changes just hours before 1.0. Makes me kind of worried...

I would be worried if that was seconds before release. Fixing bugs hours or minutes before release is just the gold standard of being agile and having God level CI/CD 🤣🤣🤣

I encountered issues with Bun, for example using it as an NPM alternative, some libraries are installed without some of their core folders inside, or it does not support async hooks from Node yet, so I would recommend to wait a bit more and see if they fix the basics

All the Python devs I've talked with have been extremely skeptical of Mojo (especially when we've had pypy and numba for years). Now that it's general availability, I'm looking forward to some unbiased cross-comparisons (and, hey, may do some myself).

[@Bersling]

Checked the page to download, requires me to log in to download. Now I'm extremely skeptical too.

[@ivanjermakov]

It's not open-source and won't be in the near future.

[@mattrs1]

I'm truly excited for Mojo.. since it's (planned to be) 100% python compatible on top of many goodies (multiple accelerator support, meant to be parallelized to hell and back) I can see future production environments totally written in Mojo things like, a webserver for an easy API, leverages AI for prompts and if it's performant enough: a Game engine that can do Serverside ML for a ton of logic as close to runtime as possible

[@fred.flintstone4099]

I am sure Mojo is alright, and it is super fast, but I don't really care. Sure it would be nice if Python was faster, but that is just one of it's problem. The poor standard library is rather shitty, with no async HTTP client in the standard library, and the JSON module cannot deserialize to classes, doing await is rather awkward since you cannot do it at top-level and need to specify an async runtime.

[@imanitrecruiterineurope4142]

Mojo is nothing new really, there's numba, custom made Cython libraries and even Jython if you really want to go the triple sec way for every needs Python conceivably could put you through. No-one is super excited because it's not open source and it's sketchy for a "corporate solution". And if we're real, all Python devs know the grind is not with making Python faster just because that's what a lot of people who don't know Python beyond Junior level complain about. It really is much, much more about finding the perfect package match for your needs and perfecting the knowledge in that area.

last quote so real

[@Android480]

I just need AWS to officially adopt bun in its runtimes. That will force 3rd party tools like Terraform, Serverless, etc to adopt them into the ecosystem. I think the point of bun is that it’s zero configuration. So until 3rd parties actually support them, I don’t want to jump through hoops to get it running

[@MartinOmander]

Go with a cloud provider which supports serverless containers. Then you can run whatever programming language you want serverlessly, as long as there is a Docker container for it. I know that Cloud Run from Google supports serverless containers. Maybe other cloud providers do too.

[@nirnullz]

It’s have docker support, so i think AWS EKS (kubernate) can use it on the pipeline easily. The terra form is just config to manage kubernates automatically, so there is no stopping if you want to use Bun on kube environment.

I remember when I first tried to learn coding with JS. Immediately gave up. Was confused about CORS and running my code. Once I understood that JS can run in AND out of browsers, I've been in a better state. Now I'm choosing between JS runtimes. Ah, what a journey

[@re.liable]

@AdrianSanchez-lu7uo JS can run in browsers via HTML. Under the tag. You open the HTML in your browser, open Dev Tools Console and see the output of your code (if any). JS can run outside browsers via JS runtimes. Node is the most prominent one. Bun is another. As well as Deno. They are "executables", and you see your code output in your terminal. I believe that's the gist of it

[@re.liable]

@AdrianSanchez-lu7uo keep on doing that. Eventually you'll need a runtime when you start studying frameworks, but you don't have to worry about it for now. IMO
