Localhost not completely stated alongside port
In the doc: println!("Server running at http://12");

params
In the Doc we have:

#[derive(Params)]
struct HelloParams {
    name: String,
}

#[handler]
fn hello(params: HelloParams) -> JsonResult {
    Ok(json!({
        "message": format!("Hello, {}!", params.name)
    }))
}

However, do you mean The Param derive macro which is used to derive a struct that can be used to parse route parameters instead ? As the above throws an error related to rustc --explain E0277

So we can have:

#[derive(Param)]
struct HelloParams {
    name: String,
}

#[handler]
fn hello(params: HelloParams) -> JsonResult {
    Ok(json!({
        "message": format!("Hello, {}!", params.name)
    }))
}

Thanks for opening this issue @komus-Israel.

Quick one did you include the prelude?

use ngyn::prelude::*;

[komus-Israel]

Yes. Added the prelude

[elcharitas]

If you added the prelude, the only other possible thing would be you dont have serde and serde_json in your application.
