Able to run web server?

Is it able to run a frontend server, like vinxi or so?

Minimal reproduction (not functional)

rusty.ts

use std::path::Path;

use rust_embed::RustEmbed;
use rustyscript::{Error, Module, Runtime, RuntimeOptions, Undefined, json_args};
use vfs::{EmbeddedFS, VfsPath};

#[derive(RustEmbed, Debug)]
#[folder = ".output"]
pub struct ServerFiles;

pub fn run() -> Result<(), Box<Error>> {
    let mut runtime = match Runtime::new(RuntimeOptions {
        ..Default::default()
    }) {
        Ok(r) => r,
        Err(e) => {
            eprintln!("Error creating runtime: {}", e);
            return Err(Box::new(Error::Runtime(e.to_string())));
        }
    };

    let fs: EmbeddedFS<ServerFiles> = EmbeddedFS::new();
    let root: VfsPath = fs.into();

    let module_path = "server/index.mjs";
    let file = root
        .join(module_path)
        .map_err(|e| Box::new(Error::Runtime(e.to_string())))?;
    let mut content = String::new();

    file.open_file()
        .map_err(|e| Box::new(Error::Runtime(e.to_string())))?
        .read_to_string(&mut content)
        .map_err(|e| Box::new(Error::Runtime(e.to_string())))?;

    runtime.set_current_dir(Path::new(root.as_str())).unwrap();

    let module = Module::new(module_path, content);
    let module_handle = runtime.load_module(&module)?;
    runtime.call_entrypoint::<Undefined>(&module_handle, json_args!())?;

    Ok(())
}

And the embedded dir structure as followed.

No idea where went wrong.

Its possible but require a lot of work.

#354 (comment):

The runtime extension required every single extension to be configured to work, including a bunch of node specific APIs

Would not make sense to activate it without node support

Got it. In this case, since nitro can specify build presets, if I insist to work on it, should I choose preset deno-server or node-server? The API between them is quite different, so I don't want to mess this up.

Very odd - it's choking on one of the extension Ops somehow

Are you adding any extensions?

Nope. Full code is above. Main file is simply running rusty::run().

If you want to I can make a minimal reproduction.

Yes please

Here you go. https://github.com/TheOrdinaryWow/unknown-arm-still

Yes please

Any update on this?

Sorry I have not had much time to work on this recently

You have not been forgotten!
