Statically importing custom modes?

[Blakeinstein]

I would be embedding ace editor into a webview, and would like to not provide paths for just a single custom js mode due to some limitations. I have plain regex token rules as of now.

What is the easiest way to achieve this? I am using parcel as the bundler. Which builds static files that are then fed into the webview.

I understand I for existing modes I can just import no-conflict variants and then use them. But how do I write one myself?
