Death

Simple library to make it easier to manage the death of your application.

Get The Library

go get github.com/vrecan/death

Use The Library

package main

import (
	DEATH "github.com/vrecan/death"
	SYS "syscall"
)

func main() {
	death := DEATH.NewDeath(SYS.SIGINT, SYS.SIGTERM) //pass the signals you want to end your application
	//when you want to block for shutdown signals
	death.WaitForDeath() // this will finish when a signal of your type is sent to your application
}

Close Other Objects On Shutdown

One simple feature of death is that it can also close other objects when shutdown starts

package main

import (
	DEATH "github.com/vrecan/death"
	SYS "syscall"
	"io"
)

func main() {
	death := DEATH.NewDeath(SYS.SIGINT, SYS.SIGTERM) //pass the signals you want to end your application
	objects := make([]io.Closer, 0)

	objects = append(objects, &NewType{}) // this will work as long as the type implements a Close method

	//when you want to block for shutdown signals
	death.WaitForDeath(objects...) // this will finish when a signal of your type is sent to your application
}

type NewType struct {
}

func (c *NewType) Close() error {
	return nil
}

Or close using an anonymous function

package main

import (
	DEATH "github.com/vrecan/death"
	SYS "syscall"
)

func main() {
	death := DEATH.NewDeath(SYS.SIGINT, SYS.SIGTERM) //pass the signals you want to end your application
	//when you want to block for shutdown signals
	death.WaitForDeathWithFunc(func(){ 
		//do whatever you want on death
	}) 
}
