Xpress: A Lightweight HTTP Library for Rust

Xpress is a minimalistic HTTP library built from scratch in Rust. It demonstrates the inner workings of web frameworks by implementing core features like routing, request parsing, and response handling in a simple, extensible way.

Note: This project is not intended for production use. It is an educational example showing how an HTTP library can be built from scratch in Rust.

Features

• Trie-Based Routing: Efficiently match static and dynamic routes using a trie structure for high-performance route lookups.
• Dynamic Route Params: Easily define routes with /:id-style parameters and extract them.
• Query Params: Parse query strings and access key-value pairs directly.
• Request Handling: Seamlessly parse incoming HTTP requests.
• Response Management: Send JSON, HTML, or plain text responses easily.
• Thread Pooling: Handle multiple client connections concurrently.
• Error Handling: Robust and customizable error handling.

Installation

Add Xpress to your project in Cargo.toml:

[dependencies]
xpress = "0.2.0"

Usage

Here’s a quick example with static routes, dynamic params, and query params:

fn main() -> Result<(), XpressError> {
    const PORT: u16 = 8080;
    let mut app = Xpress::new(&format!("127.0.0.1:{}", PORT));

    app.get("/", |_req, res| match res.html("examples/hello.html") {
        Ok(_) => Ok(()),
        Err(err) => {
            res.status(500);
            res.send(format!("Error rendering HTML: {}", err))?;
            Ok(())
        }
    });

    app.get("/test/:id", |req, res| {
        let id = req.params.get("id").unwrap();
        let foo = req.query.get("foo").unwrap();
        res.send(format!("{} {}", id.clone(), foo.clone()))?;
        Ok(())
    });

    println!("Server running on port {}", PORT);
    app.listen()?;
    Ok(())
}
