Goroutines are a fundamental feature of Go, enabling powerful concurrency and efficient multitasking. However, improperly managed goroutines can lead to goroutine leaks, which consume system resources and degrade application performance over time. In this video, we’ll explore everything you need to know about goroutine leaks, including their causes, impact, and solutions.

We start by explaining what goroutine leaks are and how they occur when goroutines fail to terminate properly. From there, we break down the key causes:
• Blocked channels waiting indefinitely for data.
• Infinite loops with no exit conditions.
• Forgotten goroutines spawned without proper termination.
• Improper context management, where cancellation or timeouts are missing.

Next, we cover how to identify goroutine leaks in your application using tools like runtime.NumGoroutine() and profiling tools like pprof.

We then provide actionable steps to prevent goroutine leaks:
• Closing channels appropriately.
• Using context.Context to handle cancellation and timeouts.
• Setting proper exit conditions in loops.
• Implementing graceful shutdowns with sync.WaitGroup.
• Leveraging select statements to handle timeouts.
• Conducting code reviews to spot orphaned or unnecessary goroutines.

Finally, we share best practices for managing goroutines effectively:
• Always pass context.Context to goroutines.
• Use defer statements to close channels.
• Regularly monitor and debug with profiling tools to catch potential leaks.

By the end of this video, you’ll understand the impact of goroutine leaks on system performance and know how to safeguard your applications against them. Whether you’re building scalable backends, real-time applications, or highly concurrent systems, these insights will help you write cleaner, more efficient Go code.

This video is packed with practical examples and tips to ensure you never let a single goroutine leak slip through again. Don’t miss it—master goroutines and keep your Go applications performing at their peak!
