I see an article that invoke / handle is asynchronous, but it's possible to use the old send / on. It is easy to return the return value. You do not need to specify webcontents when sending from Main to renderer. The benefits are understandable
https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31 I don't think the remote module written in this article is relevant to send / on
invoke is new api to help ergonomics around existing send / on pair when try to invoke some fn to return values to the sender. You can achieve same thing via send if you prefer to use it, there's no functional differences.
