Built a Concurrent Task Scheduler in Go.. github: github.com/AboloreDev/go-con… It supports: • One-off delayed tasks • Repeating interval tasks • Individual task cancellation • Full graceful shutdown Concepts used: → Goroutines for background execution → Channels for stop signaling → Mutex for safe concurrent map access → WaitGroups for lifecycle coordination How it works: - Register a task with a name + delay/interval - Scheduler spawns a goroutine per task - Timer handles initial delay, Ticker handles repeats - Stop signal sent via channel close - WaitGroup blocks until task fully completes - GlobalWaitGroup ensures clean program exit Real world use cases: 🔔 Notification & email senders 💳 Billing retry systems - Server health monitors Database cleanup jobs Cache refresh pipelines No external libraries. Pure Go stdlib.
