Embed Dashboards via Nodejs and Capacity Question

Hey folks

I'm facing a problem while trying to embed dashboards on my own website in embed mode. I have couple dashboard for ready to publish via web (non-powerbi users) I want to make it simple dashboard like in https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html but i'm stuck now how to do that? I've read a couple of thread that can about the capacity. Do i have to assign capacity to work with dashboards in embed mode?

Another question is Currently i'm using nodejs to embed reports to my own web site with zero problem now i need a deploy some embeded dashboards. Is there possible to deploy dashboards with nodejs?
