Graceful is a tiny but powerful package to ensures your application shuts down cleanly, allowing registered closers to complete their tasks before exiting.
Force shutdown are possible in case a graceful shutdown fails. If you send a kill signal (Ctrl+C) once, the application begins its shutdown process, allowing all registered closers to complete. If send a kill signal (Ctrl+C) again, the application will force quit immediately.
package main
import (
"context"
"github.com/cloudproud/graceful"
)
func main() {
ctx := graceful.NewContext(context.Background())
go ctx.Closer(func() {
// gracefully shutdown connection
})
var err error
if err != nil {
ctx.Shutdown() // initiates a graceful shutdown of the application due to a critical error
}
ctx.AwaitKillSignal()
}
