Generating Power Bi Access Token in NodeJS

Hi,

I've been trying to generate an access token to call the Power BI REST api.

I haven't had any luck following multiple tutorials where I've had various problems:

Can't get VS2015 on my machine (mac) and version 2.21.301221612 of the suggested packaged doesn't exisit

I'm trying to get an access token for a web app where the app owns the data, so I already know the credientials.

Ideally I would like an access token to stay static so I can generate embed tokens without having to get a new access token for each embed request. I would also like to contain this to NodeJS as that's what my server is written in.

Any suggestions?

Thanks!
