Electron is designed to be bundled into your app, I'm not aware of any distros/package tools that allow Electron apps to share a runtime.

The JVM (and apparently qbrt) is designed to be shared, apps are expected to use the installed system version of the VM, though if the packager wants they can include a specific version to use.

I wish it were easy/possible to get Electron apps to share things, it bothers me that Chrome, Discord, and Slack almost certainly could share most of their hundreds of megabytes.
