Racoon

Racoon is a fast, fully customizable web framework for Rust focusing on simplicity.

To use Racoon, you need minimal Rust version 1.75.0 and Tokio runtime.

Learn Racoon

Installation

You will need tokio runtime to run Racoon. Run cargo add tokio to install tokio crate.

[dependencies]
racoon = "0.1.7"

Basic Usage

use racoon::core::path::Path;
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;

async fn home(request: Request) -> Response {
    HttpResponse::ok().body("Home")
}

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

    let result = Server::bind("127.0.0.1:8080")
        .urls(paths)
        .run().await;

    println!("Failed to run server: {:?}", result);
}

File Handling

There are multiple ways to handle files in Racoon. The simple way is to use request.parse() method.

use racoon::core::request::Request;
use racoon::core::response::{HttpResponse, Response};
use racoon::core::response::status::ResponseStatus;
use racoon::core::forms::FileField;
use racoon::core::shortcuts::SingleText;

async fn upload_form(request: Request) -> Response {
    if request.method == "POST" {
        // Parses request body
        let (form_data, files) = request.parse().await;
        println!("Name: {:?}", form_data.value("name"));

        let file = files.value("file");
        println!("File: {:?}", file);
        return HttpResponse::ok().body("Uploaded");
    }

    HttpResponse::bad_request().body("Use POST method to upload file.")
}

WebSocket example

use racoon::core::path::Path;
use racoon::core::request::Request;
use racoon::core::response::Response;
use racoon::core::server::Server;
use racoon::core::websocket::{Message, WebSocket};

use racoon::view;

async fn ws(request: Request) -> Response {
    let (websocket, connected) = WebSocket::from(&request).await;
    if !connected {
        // WebSocket connection didn't success
        return websocket.bad_request().await;
    }

    println!("WebSocket client connected.");

    // Receive incoming messages
    while let Some(message) = websocket.message().await {
        match message {
            Message::Text(text) => {
                println!("Message: {}", text);

                // Sends received message back
                let _ = websocket.send_text(text.as_str()).await;
            }
            _ => {}
        }
    }
    websocket.exit()
}

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

    let _ = Server::bind("127.0.0.1:8080")
        .urls(paths)
        .run().await;
}
