`zap` :zap:

The mission of zap is, to deliver a fast rust web framework that just supports the basics.

About

This code is based on tokio's minihttp project, so a big thanks to them. (source)

How to use

Add the following to your Cargo.toml: toml [dependencies] zap = { git = "https://github.com/oldaniel/zap" }

Speed

So zap is not only fast, it is wapping x2,7 times faster than iron which is based on hyper. Benchmarks below:

Benchmark Code

Iron

This code had been taken from the ironframework.io webpage.

```rust extern crate iron;

use iron::prelude::*; use iron::status;

fn main() { fn helloworld(: &mut Request) -> IronResult { Ok(Response::with((status::Ok, "Hello World!"))) }

let _server = Iron::new(hello_world).http("localhost:3000").unwrap();
println!("On 3000");

} ```

Zap

This example can be run, by:

$ git clone https://github.com/oldaniel/zap && cd zap $ cargo run --example hello-world --release

```rust extern crate zap;

use std::io;

use zap::{Server, Http, Handler, ZapResult, Request, Response};

struct HelloWorld;

impl Handler for HelloWorld { type Request = Request; type Response = Response; type Error = io::Error; type Future = ZapResult;

fn call(&self, _: Request) -> ZapResult {
    let mut resp = Response::new();

    resp.body("Hello World!");

    resp.ok()
}

}

fn main() { let addr = "0.0.0.0:8080".parse().unwrap(); let mut server = Server::new(Http, addr); server.threads(8); server.serve(|| Ok(HelloWorld)); } ```

Benchmark Results

The benchmarks had been done with the following command: wrk -t16 -c500 -d10s http://127.0.0.1:8080 --latency

Technical details about the server:

Intel Core I7-6700K, hyperthreaded
16GB RAM, 2400MHZ

Todo

Some things we still need to make:

[ ] Make it faster
[ ] URL and body parsing
[ ] Request key storing
