Middleware

The middleware can run before processing the response and after the response.

You can perform task like logging, serving static files or security checks inside the wrap middleware function.

Basic Usage

You need to use wrap_view! macro to wrap async middleware view.

use racoon::core::path::{Path, View};
use racoon::core::request::Request;
use racoon::core::response::{HttpResponse, Response};
use racoon::core::response::status::ResponseStatus;
use racoon::core::server::Server;

use racoon::{view, wrap_view};

async fn middleware(mut request: Request, view: Option<View>) -> Response {
    if request.path == "/old" {
        return HttpResponse::temporary_redirect().location("/new");
    }

    Path::resolve(request, view).await
}

async fn hello_world(request: Request) -> Response {
    HttpResponse::ok().body("Hello World")
}

#[tokio::main]
async fn main() {
    let paths = vec![
        Path::new("/", view!(hello_world))
    ];

    let _ = Server::bind("127.0.0.1:8080")
        .wrap(wrap_view!(middleware)) // Wrap middleware
        .urls(paths)
        .run().await;
}
