hmm. this should work (and does when i try it locally). are you sure the js file you have in index.html is the right one? also, can you add `println` statements to verify that your code is being executed? last thing to consider is whether `display.size` is empty by chance. that would mean your view has no size. as defined, your view's size will be a fixed value and won't change as you resize the window. you can fix that by doing:

```class HelloDoodle(display: Display): Application {
    init {
        val view = view {
            render = {
                text("Hello, Doodle!", color = Black)
            }
        }

        display += view
        display.fill(White.paint)
        display.layout = constrain(view, fill) // adds a constraint based layout that causes view to fit the display
    }

    override fun shutdown() {}
}```

Yeah, you are right, it was the wrong js file. I misspelt its name. Thank you very much. As you understand I am a newbie, so sorry for the stupid questions
