Problem Description

Once Electron v28 makes it to stable and we see wider adoption of ESM in the main process, we lose require.main.filename and when the Electron app is packaged to is a great way to get the entry script.

Proposed Solution

app.mainStartupScript?

Alternatives Considered

In Node you can just use process.argv[1] but there is no path supplied in the args in packaged Electron apps.
