Getting Started

Dependencies

[dependencies]
volga = "0.7.2"
tokio = { version = "1", features = ["full"] }

Simple request handler

use volga::{App, ok};

#[tokio::main]
async fn main() -> std::io::Result<()> {
    // Start the server
    let mut app = App::new();

    // Example of a request handler
    app.map_get("/hello/{name}", async |name: String| {
        ok!("Hello {name}!")
    });
    
    app.run().await
}

Tested a single instance on a laptop using 4 threads and 500 connections and under configuration:

OS: Arch Linux
CPU: Intel i7-8665U (8) @ 4.800GHz
RAM: 31686MiB
