lil-http

A barebones HTTP 1.1 framework, built in Rust with no external dependencies (other than tokio).

Features

• [x] Listening to incoming requests
• [x] Parsing method, path, query, headers, and body according to the HTTP 1.1 spec
• [x] Responding to requests with an arbitrary body and headers
• [x] Helpers for responding with text or JSON
• [x] Allow defining routes and methods as closures
• [x] Appropiately routing the request to its function, or 404'ing otherwise
• [x] Appropiately crafting and returning 405 errors on invalid methods.

Usage

```rust use lil_http::{Body, Response, Server};

[tokio::main]

async fn main() { let mut http = Server::new().unwrap();

http.routes
    .get("/", |request| {
        println!("Received {} request to {}", request.method, request.path);

        Response::text(
            format!(
                "Hello, {}!",
                request.query.get("name").unwrap_or(&"World".to_string())
            )
            .as_str(),
        )
    })
    .get("/api/user", |request| {
        println!("Received {} request to {}", request.method, request.path);

        Response::json(&serde_json::json!({
            "name": "Miguel Piedrafita",
            "age": 20,
        }))
    })
    .post("/api/hello", |request| {
        println!("Received {} request to {}", request.method, request.path);

        let Body::Json(body) = request.body else {
            return Response::invalid_request();
        };

        let Some(name) = body.get("name") else {
            return Response::invalid_request();
        };

        Response::json(&serde_json::json!({
            "message": format!("Hello, {name}!"),
        }))
    });

http.run().await;

} ```
