Is it possible to interop with GDScript and JS/TS?

[KameiKojirou]

My apologies if I missed it. Can Godot-js interop GDScript with JS/TS for extending scripts? I really like the ergonomics of using GDScript for most of the game logic, I'm primarily interested in extending it with Node. Is something like this possible in GodotJS? Also is there any limitations on mobile?

Grow-GD Example

extends Node


@onready var go = GoUtils.new()
@onready var number_one = $HBoxContainer/Num1SpinBox
@onready var number_two = $HBoxContainer/Num2SpinBox
@onready var result = $HBoxContainer/LabelTotal

# Called when the node enters the scene tree for the first time.
func _ready():
	print(go.multiply(6, 7))


func _on_button_pressed() -> void:
	result.text = "calculated: " + str(go.multiply(int(number_one.value), int(number_two.value)))

package main

import (
    "graphics.gd/classdb"
    "graphics.gd/startup"
    "graphics.gd/variant/RefCounted"
)

type GoUtils struct {
    classdb.Extension[GoUtils, RefCounted.Instance] `gd:"GoUtils"`
}

func (utils *GoUtils) Multiply(a, b int32) int32 { return a * b }

func main() {
    classdb.Register[GoUtils]()
    startup.Scene()
}

Godot-Rust Example

extends Node2D


@onready var rust = RustUtils.new()
@onready var number_one = $VBoxContainer/HBoxContainer/Num1SpinBox
@onready var number_two = $VBoxContainer/HBoxContainer/Num2SpinBox
@onready var result = $VBoxContainer/HBoxContainer/LabelTotal


@onready var hellolabel = $VBoxContainer/HBoxContainer2/HelloLabel
@onready var helloLineEdit = $VBoxContainer/HBoxContainer2/HelloLineEdit
@onready var helloButton = $VBoxContainer/HBoxContainer2/HelloButton

var helloname: String = ""

# Called when the node enters the scene tree for the first time.
func _ready():
	print(rust.multiply(6, 7))

func _on_button_pressed() -> void:
	result.text = str(rust.multiply(int(number_one.value), int(number_two.value)))

func _on_hello_button_pressed() -> void:
	hellolabel.text =str(rust.hello(helloLineEdit.text))

use godot::prelude::*;

#[derive(GodotClass)]
#[class(base=RefCounted, init)]
pub struct RustUtils {
    #[base]
    base: Base<RefCounted>,
}

#[godot_api]
impl RustUtils {
    #[func]
    fn multiply(&self, a: i32, b: i32) -> i32 {
        a * b
    }

    #[func]
    fn hello(&self, name: String) -> String {
        format!("Hello {}!", name)
    }
}

Hey, @KameiKojirou at the moment the new method is not implemented.

It might be possible if new would be implemented correctly

No worries, thank you!
