> Look, I don’t know where we are going.

As honest as it is I can't risk using this anywhere near production if this is the attitude.

Luckily there's a lot of people who write prototype code, toy projects, and other "non-production" code that can experiment with a new project like this

I'd rather honestly than false confidence, there's something admirable about being this clear for sure

Has anyone here tried it?
haellsigh•32m ago
I have tried it. It feels pretty good to use, but you have to keep in mind that it's very early software. They currently break the API every other week, and it's still missing a lot of fundamental features. I have made a few basic web apps with it, and on v0.8.1 it was still missing a lot of reactivity which meant you had to use Javascript to bridge the gap.

I used it in the early days, and it seems it's still the same. Thank you.

We’re using it to build our web app (https://uncook.xyz) and while it’s a slight departure from my team’s NodeJS background it’s been pretty cool to work with

Sounds a lot like Liveview in Phoenix.

Why bother with rust when you can write it in C and ask an LLM to weed out the memory bugs?

Because fuck borrow checker..(and the horrible syntax)

If you go that way, why not write LLVM Intermediate Representation? And if you know your server arch anyway, why not write machine code?

I personally like Rust for web applications a lot because you can catch many bugs at compile time instead of during tests or runtime.

Soon we're gonna need a way to catch bugs at prompt time
