How to build js client library don't need to used with type="module" in script tag?

[dante01yoon]

Greetings,

I build chat app which installed with single script tag like <script src="host.com/something.js"></script>

but without add type="module", app doesn't work.

I see potential issues for client who use my app in old browser, so I want to remove type="module".

how can I achieve this?

plugin-legacy does not support libraries, like this question asked

I covered this with rollup config

actually for my part, i later realized that universal module definition works just as well, which for me raises the question of what the legacy plugin was even needed for, but oh well - maybe this helps someone. just copy and past the UMD into the browser repl and watch your globals get instantiated.
