// Package scheduler provides a GitHub Actions-inspired cron job scheduler.
|
|
//
|
|
// Features:
|
|
// - Standard cron expression syntax (5-field and 6-field formats)
|
|
// - Timezone-aware scheduling
|
|
// - Middleware pattern for cross-cutting concerns (logging, metrics, recovery)
|
|
// - Graceful shutdown with context cancellation
|
|
// - Zero external dependencies
|
|
//
|
|
// Basic usage:
|
|
//
|
|
// s := scheduler.New()
|
|
//
|
|
// s.Register(&scheduler.Job{
|
|
// Name: "daily-cleanup",
|
|
// Schedule: "0 2 * * *", // 2 AM daily
|
|
// Handler: func(ctx context.Context) error {
|
|
// // Your cleanup logic here
|
|
// return nil
|
|
// },
|
|
// })
|
|
//
|
|
// s.Start()
|
|
// defer s.Stop(context.Background())
|
|
//
|
|
// With middleware:
|
|
//
|
|
// s := scheduler.New(
|
|
// scheduler.WithTimezone("America/New_York"),
|
|
// scheduler.WithMiddleware(
|
|
// scheduler.Recovery(),
|
|
// scheduler.Logging(),
|
|
// ),
|
|
// )
|
