Running the code block periodically

Besides the date and time operations, the time package also provides support for periodic and delayed code execution. Typically, the application health checks, activity checks, or any periodic job can be implemented this way.

How to do it...

1. Open the console and create the folder chapter04/recipe09.
2. Navigate to the directory.
3. Create the ticker.go file with the following content:

        package main

        import (
          "fmt"
          "os"
          "os/signal"
          "time"
       )

       func main() {

         c := make(chan os.Signal, 1)
         signal.Notify(c)

         ticker := time.NewTicker(time.Second)
         stop := make(chan bool)

         go func() {
           defer func() { stop <- true }()
           for {
             select {
               case <-ticker.C:
                 fmt.Println("Tick")
               case <-stop:
                 fmt.Println("Goroutine closing")
                 return
             }
   ...
