Ruffus is a web framework for Rust inspired by Express.js, designed to make building web APIs fast, simple, and enjoyable. With an ergonomic API and powerful async runtime, Ruffus lets you focus on building features, not fighting the framework.

Status: ✅ Published on crates.io | 🧪 107 tests passing (8 unit + 43 property-based + 56 doc tests)

use ruffus::{App, Request, Response};

#[tokio::main]
async fn main() {
    let mut app = App::new();
    
    app.get("/", |_req: Request| async {
        Response::text("Hello, World!".to_string())
    });
    
    app.listen("127.0.0.1:3000").await.unwrap();
}

✨ Features

• 🚀 Blazing Fast - Built on Tokio and Hyper for maximum performance
• 🎯 Type-Safe - Leverage Rust's type system to catch errors at compile time
• 🔌 Middleware - Composable middleware for cross-cutting concerns
• 📦 JSON Support - First-class JSON serialization with Serde
• 🛣️ Flexible Routing - Express-style routing with path parameters
• ⚡ Async/Await - Native async support for non-blocking I/O
• 🎨 Ergonomic API - Intuitive, chainable methods inspired by Express.js
• 🔧 Modular - Organize routes with routers and mount them anywhere

📦 Installation

Add Ruffus to your Cargo.toml:

[dependencies]
ruffus = "0.1"
tokio = { version = "1", features = ["full"] }
serde = { version = "1.0", features = ["derive"] }

Or install from the command line:

cargo add ruffus
cargo add tokio --features full
cargo add serde --features derive

🚀 Quick Start

Basic Server

use ruffus::{App, Request, Response};

#[tokio::main]
async fn main() {
    let mut app = App::new();
    
    app.get("/hello/:name", |req: Request| async move {
        let name = req.param("name").unwrap_or("stranger");
        Response::text(format!("Hello, {}!", name))
    });
    
    app.listen("127.0.0.1:3000").await.unwrap();
    println!("Server running on http://127.0.0.1:3000");
}

JSON API

use ruffus::{App, Request, Response};
use serde::{Deserialize, Serialize};

#[derive(Deserialize)]
struct CreateUser {
    name: String,
    email: String,
}

#[derive(Serialize)]
struct User {
    id: u64,
    name: String,
    email: String,
}

#[tokio::main]
async fn main() {
    let mut app = App::new();
    
    app.post("/users", |mut req: Request| async move {
        let body: CreateUser = req.json().await?;
        
        let user = User {
            id: 1,
            name: body.name,
            email: body.email,
        };
        
        Response::json(&user)
    });
    
    app.listen("127.0.0.1:3000").await.unwrap();
}

Middleware

use ruffus::{App, Request, Response, middleware::{Middleware, Next}};
use async_trait::async_trait;

struct Logger;

#[async_trait]
impl Middleware for Logger {
    async fn handle(&self, req: Request, next: Next) -> Result<Response> {
        println!("{} {}", req.method(), req.uri());
        let start = std::time::Instant::now();
        
        let response = next.run(req).await?;
        
        println!("Request took {:?}", start.elapsed());
        Ok(response)
    }
}

#[tokio::main]
async fn main() {
    let mut app = App::new();
    
    app.use_middleware(Logger);
    
    app.get("/", |_req: Request| async {
        Response::text("Hello!".to_string())
    });
    
    app.listen("127.0.0.1:3000").await.unwrap();
}

Routers

use ruffus::{App, Router, Request, Response};

#[tokio::main]
async fn main() {
    let mut app = App::new();
    
    // API v1 routes
    let mut api_v1 = Router::new("/api/v1");
    
    api_v1.get("/users", |_req: Request| async {
        Response::json(&vec!["Alice", "Bob", "Charlie"])
    });
    
    api_v1.get("/users/:id", |req: Request| async move {
        let id = req.param("id").unwrap();
        Response::json(&format!("User {}", id))
    });
    
    // Mount the router
    app.mount("/", api_v1);
    
    app.listen("127.0.0.1:3000").await.unwrap();
}

🔧 API Overview

Application

let mut app = App::new();

app.get("/path", handler);      // GET route
app.post("/path", handler);     // POST route
app.put("/path", handler);      // PUT route
app.delete("/path", handler);   // DELETE route
app.patch("/path", handler);    // PATCH route

app.use_middleware(middleware); // Add middleware
app.mount("/prefix", router);   // Mount router

app.listen("127.0.0.1:3000").await?; // Start server

Request

req.method();              // HTTP method
req.uri();                 // Request URI
req.headers();             // HTTP headers
req.param("name");         // Path parameter
req.query("key");          // Query parameter
req.json::<T>().await?;    // Parse JSON body

Response

Response::text(string);           // Plain text response
Response::json(&data)?;           // JSON response
Response::new()
    .status(StatusCode::OK)
    .header("X-Custom", "value")
    .text("body");                // Builder pattern
