Laravel Mix - expose function to be used in browser

I have a typescript file that I would like to build with mix, and then use it in another page as a javascript library. i.e:

<script type="module" src="/js/index.js">
    console.log("test");
</script>

How can I achieve this with mix?

I was able to use mix.ts('resources/index.ts', 'public/js') to create the file, but all attempts to use the functions inside the file:

i.e:

    import getInfo from '/js/index.js'

    import {getInfo} from '/js/index.js'

all result in similar errors: The requested module '/js/index.js' does not provide an export named 'default', The requested module '/js/index.js' does not provide an export named 'getInfo'

When I look in js/index.js I can actually see the methods that I want to use, so I know they were somewhat exported. But I'm not sure how I can actually use the function.

I've checked the window variable and the functions are also not there.

Thank you
