Unfortunately, it seems pretty complicated. You probably won't be able to add variables to .html you render in electron in a nice way.

Of course - you can use url but it slows down booting very much (vy seconds) or you can execute Javascript in BrowserWindo, which also slows boot down.

The only way is the IPC and leaving javascript .html agnostic to variables from main process. Very sad though..
