# Zumi's Writings

Just random Zumi Zoom things

## 1. What's “module” mode?

Basically it's the adoption of ES modules-style imports to the browser. They look nice, but they are now strongly isolated. That means, code modifying global variables like window are no longer possible. Sounds great, until you realize that it's one of the “normal” way for HTML-inlined JS to work with “imported” JS.

What we have instead is an export mechanism, which does what you think, just like how ES modules work in Node.js, TypeScript and the like. You can even import them from the browser, like this:

<script type="module">
import { func } from "./module.js";

// call func
func();
</script>


However I'm not yet sure on how those things work yet. One thing I know is that I've been abusing globals like window for most interaction with go-generated HTML and independent TypeScript code in kjudge.

And that did not go well with Parcel 2...

## 2. Parcel 2

Parcel 2 decided to push the standard to the extreme, requiring all TS/JS code with imports to be imported (from HTML) as modules. This means that as long as you import anything (not just other JS/TS files but also images, audio, ... anything you can think of with a Parcel magic import), you live with an isolated JS/TS file. Why is this a strong requirement? I get it for code import, but for resources they don't make a lot of sense, especially when they also are making it explicit that what you get is just an URL...

Even worse, Parcel has some logic to inline the script content into the HTML once imported, making static global variables totally impossible (yay?).

## 3. Pain

I haven't found a nice way out of this yet. Perhaps changing inlining rules? Perhaps a way to compromise with the import algorithm?

We'll see once I have time for this again :)

## Welcome to another attempt at writing stuff...

Things should work now as they should. Or so I hope.

Giving some code a try...

str :: String
str = "Hello World!"

main :: IO ()
main = putStrLn str


See ya :3
