go-selfupdate

Enable your Golang applications to self update. Inspired by Chrome based on Heroku's hk.

Features

• Tested on Mac, Linux, Arm, and Windows
• Creates binary diffs with bsdiff allowing small incremental updates
• Falls back to full binary update if diff fails to match SHA

QuickStart

Install library and update/patch creation utility

go get -u github.com/sanbornm/go-selfupdate/...

Enable your App to Self Update

var updater = &selfupdate.Updater{
	CurrentVersion: version,
	ApiURL:         "http://updates.yourdomain.com/",
	BinURL:         "http://updates.yourdomain.com/",
	DiffURL:        "http://updates.yourdomain.com/",
	Dir:            "update/",
	CmdName:        "myapp", // app name
}

if updater != nil {
	go updater.BackgroundRun()
}

Push Out and Update

go-selfupdate myapp 1.2

This will create a folder in your project called, public you can then rsync or transfer this to your webserver or S3.

If you are cross compiling you can specify a directory:

go-selfupdate /tmp/mybinares/ 1.2

The directory should contain files with the name, $GOOS-$ARCH. Example:

windows-386
darwin-amd64
linux-arm

If you are using goxc you can output the files with this naming format by specifying this config:

"OutPath": "{{.Dest}}{{.PS}}{{.Version}}{{.PS}}{{.Os}}-{{.Arch}}",
