Parcel bundling Javascript on iOS
I have this roll-your-own iOS Web app (not using any framework in particular).
(Oh and don't ask me why I don't just use React Native or Cordova related stuffs. :/ I would totally prefer them. The project is just handed to me this way. )
I want to write new code with ES6 while leaving old code mostly intact. So I created a new directory, and inside it I put my ES6 code, and I wrote an "main.js" to import all the files I wanted, like the following:
import { BluetoothLE } from './Bluetooth/BluetoothLE.js';
window.BluetoothLE = BluetoothLE; // Just want to make stuff global here
console.log('main.js run');
I used Parcel bundler to bundle into one Javascript file:
parcel build ./www/lib/main.js --out-dir='./www/dist'
And include it in index.html very traditionally:
<script src="./dist/main.js"></script>
<script language="JavaScript">
// vanilla code within this block which uses stuff from main.js
</script>
I expect stuff in the main.js to ran on load. It works on desktop Chrome. However, when build into iOS (iOS 10 in particular, if that matters), main.js doesn't get run -- "main.js run" is not printed.
Why is that? Any hack or method I can get ES6 stuff to run with minimal effort without changing other legacy, vanilla Javascript code is welcome.
EDIT: I ended up using Webpack instead and it works.

I would have taken a look at the compiled scripts and HTML, then fiddled with the CLI options. But it seems you found a way to use Webpack instead.
