The update manager in systray over rsync written in go.
Props:
- cross-platform
- simple
- fast
- configurable
- Lightweight
- no runtime dependencies
This update manager puts files of the new version into the directory with the previous version. It uses rsync implementation written in go so it is pretty fast.
In practice, It has problems with cross-compilation, and It needs the same host OS as the target.
I faced an open issue in the systray module that didn't let me compile for macOS from a Linux host - getlantern/systray#34
See settings.toml file.
Your app files should be available through the rsync server and http server (nginx or else) same directory.
It should have 2 types of version files:
- VERSION (fixed name of file)
- version-1.2.3.txt (files that contain version value in the name of the file)
The VERSION file contains the latest version of your app (remote or local).
The "version-x.y.z.txt" new file saves each time an update happens.
A command like ls version-*.txt returns a list of installed versions.
It uses a few cross-platform (Win, Linux, macOS) modules:
It uses other useful native modules also:
- go-toml
- gocrasy/rsync (just copied sources)
- lumberjack - log rotation
