For fully automatic macOS updates, electron-updater requires:
1. Distributing macOS file as .zip (electron-userland/electron-builder#2199)
2. Code signing for the application
privacy.sexy as of today lacks both the distribution and code signing.
This commit introduces auto-updates through automatically checking for
updates, downloading them but requiring user to drag application icons
to Applications by opening dmg file.
This commit also fixes:
1. Progress state in update progress bar not being shown.
2. Downloading updates were being triggered even though it was not
desired as downloads are being handled using different based on OS and
user choice.
In the end it refactors the code for handling updates of two different
kinds, and making message dialog use enums for results instead of
response integers as well as setting default and cancel button behavior.
Refactorings make behaviors more explicit and extends the control.
Before we used native method from electron for updating and notifying
(`checkForUpdatesAndNotify`). It simply checked if there's an update,
downloaded it, applied in the background and showed OS notification.
The flow is now updated. Updates will be checked, user will be asked to
confirm about whether to download and apply the updates, then a UI with
progress bar will be shown and user will be asked to restart the
application.
This commit also moves electron related logic to `/electron/` folder (as
there are now multiple files) to keep them structured. Also the electon
entrypoint `background.ts` is renamed to `main.ts`. The reason it was
named `background.ts` by vue-cli-plugin-electron-builder was to remove
the confusion between `main.ts` of Vue itself. However, as they are
kept in different folders, but this is not the case for us.
Better than `checkForUpdatesAndNotify`.
Organizes electron desktop app logic in same folder to allow using
multiple files in a structured manner.
