🐙 Tako — Lightweight Async Web Framework in Rust

Tako ("octopus" in Japanese) is a pragmatic, ergonomic and extensible async web framework for Rust. It aims to keep the mental model small while giving you first‑class performance and modern conveniences out‑of‑the‑box.

⚠️ Early-stage software ⚠️ Beta software: Tako is still under active development; use with caution and expect breaking changes.

✨ Highlights

• Batteries‑included Router — Intuitive path‑based routing with path parameters and trailing‑slash redirection (TSR).
• Extractor system — Strongly‑typed request extractors for headers, query/body params, JSON, form data, etc.
• Streaming & SSE — Built‑in helpers for Server‑Sent Events and arbitrary Stream responses.
• Middleware — Compose synchronous or async middleware functions with minimal boilerplate.
• Shared State — Application‑wide state injection without unsafe globals.
• Plugin system — Opt‑in extensions let you add functionality without cluttering the core API.
• Hyper‑powered — Built on hyper & tokio for minimal overhead and async performance with native HTTP/2 & TLS support.
• GraphQL integration — Async-GraphQL integration for Tako: extractors, responses, and subscriptions.

📦 Installation

Add Tako to your Cargo.toml:

[dependencies]
tako-rs = "*"

🚀 Quick Start

Spin up a "Hello, World!" server in a handful of lines:

use anyhow::Result;
use tako::{
    responder::Responder,
    router::Router,
    types::Request,
    Method,
};
use tokio::net::TcpListener;

async fn hello_world(_: Request) -> impl Responder {
    "Hello, World!".into_response()
}

#[tokio::main]
async fn main() -> Result<()> {
    // Bind a local TCP listener
    let listener = TcpListener::bind("127.0.0.1:8080").await?;

    // Declare routes
    let mut router = Router::new();
    router.route(Method::GET, "/", hello_world);

    // Launch the server
    tako::serve(listener, router).await;

    Ok(())
}
