Velopack Go

It's easy to distribute Go desktop applications with automatic updates!

1. Add this module to your project:

$ go get github.com/quaadgras/velopack-go

2. Add automatic updates to your project:

Here's as a one-liner, that will download updates in the background and apply them the next time the application starts up:

go velopack.DownloadUpdatesInTheBackground("https://the.place/you-will-host/updates")

Alternatively, you can also develop your own update function:

package main

import "github.com/quaadgras/velopack-go/velopack"

func init() {
  velopack.Run(velopack.App{
  	AutoApplyOnStartup: true,
  })
}

func update() error {
	manager, err := velopack.NewUpdateManager("https://the.place/you-will-host/updates")
	if err != nil {
		return err
	}
	latest, status, err := manager.CheckForUpdates();
	if err != nil {
		return err
	}
	if status == velopack.UpdateAvailable {
		if err := manager.DownloadUpdates(latest, func(progress uint){
			// show progress to the user
		}); err != nil {
			return err
		}
		if err := manager.ApplyUpdatesAndRestart(latest); err != nil {
			return err
		}
	}
	return nil
}

3. Follow the official Velopack guide to package your application for distribution.
