Nope didn't say to "integrate it for me".

Simply said I expect there to be an npm to use in case I don't want to use the hosted UI. Very common, almost everyone does it. I would even expect that of free-to-use SaaS.

Example: https://www.npmjs.com/package/easyinvoice

Not to mention it's pretty low effort to build to a dist and npm publish - it would be very worth it to get more people using the product. That's why it's so common.
