Graceful shutdown

The graceful shutdown is a mechanism that allows the application to finish the current requests before shutting down. This is useful to avoid losing data or to avoid corrupting the data.

The package provides an abstraction to handle the graceful shutdown. It listens to the SIGINT and SIGTERM signals and calls the Shutdown method.

Usage

package main

import (
	"context"
	"time"

	"github.com/daxartio/goshutdown"
)

func main() {
	server := &Server{}

	go server.Run()

	err := goshutdown.New().
		WithTimeout(10 * time.Second).
		WithHandler(func(ctx context.Context) error {
			println("Shutting down...")

			server.Stop(ctx)

			return nil
		}).Wait()
	if err != nil {
		println(err.Error())
	}
}

Wait waits for the shutdown signal to be received or the timeout to expire. It returns an error if the shutdown process encounters an error or if the timeout is exceeded.
