🚀 Quick Start

Server

use aerosocket::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let server = aerosocket::Server::builder()
        .bind("0.0.0.0:8080")
        .max_connections(10_000)
        .with_rate_limiting(60, 10) // 60 requests/min, 10 connections per IP
        .with_tls("cert.pem", "key.pem")?
        .build()?;

    server.serve(|mut conn| async move {
        while let Some(msg) = conn.next().await? {
            match msg {
                Message::Text(text) => conn.send_text(text).await?,
                Message::Binary(data) => conn.send_binary(data).await?,
                Message::Ping => conn.send_pong().await?,
                _ => {}
            }
        }
        Ok(())
    }).await?;

    Ok(())
}

Client

use aerosocket::prelude::*;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = aerosocket::Client::connect("wss://echo.websocket.org")
        .with_header("Authorization", "Bearer token")
        .connect()
        .await?;

    client.send_text("Hello, AeroSocket!").await?;

    while let Some(msg) = client.next().await? {
        println!("Received: {:?}", msg);
        break;
    }

    Ok(())
}

Add to your Cargo.toml:
