goalarm

Run job periodically or at specific time.
Job is a function that accept context.Context and return interface{} and error.
Job will be executed in different goroutine than the caller.
Cancel periodically executed job using cancel function returned from context.WithCancel(context.Background()). For more use case take a look at its tests.

    fmt.Println("hello")
    return nil, nil
})
// Print "hello" every 10 seconds.
goalarm.Every(ctx, 10*time.Second, 0, func(ctx context.Context) (interface{}, error) {
    fmt.Println("hello")
    return nil, nil
