Package update provides functionality to implement secure, self-updating Go programs (or other single-file targets) A program can update itself by replacing its executable file with a new version.
It provides the flexibility to implement different updating user experiences like auto-updating, or manual user-initiated updates. It also boasts advanced features like binary patching and code signing verification.
Example of updating from a URL:
import (
"fmt"
"net/http"
"github.com/inconshreveable/go-update"
)
func doUpdate(url string) error {
resp, err := http.Get(url)
if err != nil {
return err
}
defer resp.Body.Close()
err := update.Apply(resp.Body, update.Options{})
if err != nil {
// error handling
}
return err
}
equinox.io is a complete ready-to-go updating solution built on top of go-update that provides:
