Crate features

• Macro-free routing handling
• serde integration for parsing request body
• [todo] Handlers registered by macros
• [todo] OpenApi support
• custom Middleware integration
• [todo] custom Dependency Injection integration

[todo] Custom middleware include pre-implemented commonly used middlewares like [middleware..].
Custom Dependency Injection provides a flexibility to control the dependencies like database connection or other external integrations.

Usage example

in Cargo.toml:

[dependencies]
nova_web = "0.0.1"
tokio = "1.32"
serde = { version = "1.0", features = ["derive"] }

use nova_web::prelude::*;

#[derive(Debug, Deserialize, Serialize)]
struct RequestBody {
    id: String,
    name: String,
}

fn hello_world(_: &HttpRequest, res: &mut HttpResponse) -> ServerResponse {
    Ok(res
        .status(HttpStatus::OK)
        .body("Hello, world!".as_bytes()))
}

fn hello_json(req: &HttpRequest, res: &mut HttpResponse) -> ServerResponse {
    let body: RequestBody = req.json()?;
    Ok(res
        .status(HttpStatus::OK)
        .body(format!("Hello, {}!", body.name).as_bytes()))
}

#[tokio::main]
async fn main() -> Result<(), ServerError> {
    Server::create("0.0.0.0", 3000)
        .service("/hello", vec![
            get("/", hello_world),
            post("/json", hello_json),
        ].into())
        .bind()
        .await
}
