Routerify
Routerify provides a lightweight, idiomatic, composable and modular router implementation with middleware support for the Rust HTTP library hyper.
Routerify's core features:
- 🌀 Design complex routing using scopes and middlewares
- 🚀 Fast route matching using
RegexSet - 🍺 Route handlers may return any HttpBody
- ❗ Flexible error handling strategy
- 💁
WebSocketsupport out of the box. - 🔥 Route handlers and middleware may share state
- 🍗 Extensive documentation and examples
To generate a quick server app using Routerify and hyper, please check out hyper-routerify-server-template.
Compiler support: requires rustc 1.48+

Install
Add this to your Cargo.toml file:
[dependencies]
routerify = "3"
hyper = "0.14"
tokio = { version = "1", features = ["full"] }Basic Example
A simple example using Routerify with hyper would look like the following:
use hyper::{Body, Request, Response, Server, StatusCode};
// Import the routerify prelude traits.
use routerify::prelude::*;
use routerify::{Middleware, Router, RouterService, RequestInfo};
use std::{convert::Infallible, net::SocketAddr};
// Define an app state to share it across the route handlers and middlewares.
struct State(u64);
// A handler for "/" page.
async fn home_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> {
// Access the app state.
let state = req.data::<State>().unwrap();
println!("State value: {}", state.0);
Ok(Response::new(Body::from("Home page")))
}
// A handler for "/users/:userId" page.
async fn user_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> {
let user_id = req.param("userId").unwrap();
Ok(Response::new(Body::from(format!("Hello {}", user_id))))
}
// A middleware which logs an http request.
async fn logger(req: Request<Body>) -> Result<Request<Body>, Infallible> {
println!("{} {} {}", req.remote_addr(), req.method(), req.uri().path());
Ok(req)
}
// Define an error handler function which will accept the `routerify::Error`
// and the request information and generates an appropriate response.
async fn error_handler(err: routerify::RouteError, _: RequestInfo) -> Response<Body> {
eprintln!("{}", err);
Response::builder()
.status(StatusCode::INTERNAL_SERVER_ERROR)
.body(Body::from(format!("Something went wrong: {}", err)))
.unwrap()
}
// Create a `Router<Body, Infallible>` for response body type `hyper::Body`
// and for handler error type `Infallible`.
fn router() -> Router<Body, Infallible> {
// Create a router and specify the logger middleware and the handlers.
// Here, "Middleware::pre" means we're adding a pre middleware which will be executed
// before any route handlers.
Router::builder()
// Specify the state data which will be available to every route handlers,
// error handler and middlewares.
.data(State(100))
.middleware(Middleware::pre(logger))
.get("/", home_handler)
.get("/users/:userId", user_handler)
.err_handler_with_info(error_handler)
.build()
.unwrap()
}
#[tokio::main]
async fn main() {
let router = router();
// Create a Service from the router above to handle incoming requests.
let service = RouterService::new(router).unwrap();
// The address on which the server will be listening.
let addr = SocketAddr::from(([127, 0, 0, 1], 3000));
// Create a server by passing the created service to `.serve` method.
let server = Server::bind(&addr).serve(service);
println!("App is running on: {}", addr);
if let Err(err) = server.await {
eprintln!("Server error: {}", err);
}
