golang-concurrency-patterns

What problem does it solve?

This Skill helps developers write robust and efficient concurrent Go applications by providing patterns to avoid common pitfalls like deadlocks, data races, and goroutine leaks.

Core Features & Use Cases

• Context Propagation: Ensures cancellation signals are passed correctly through goroutines.
• Error Handling: Utilizes errgroup for coordinated concurrent task execution and error propagation.
• Resource Management: Demonstrates bounded concurrency using semaphores and worker pools to prevent resource exhaustion.
• Use Case: When building a microservice that processes multiple requests concurrently, use these patterns to ensure that if one request fails, others are gracefully cancelled, and that the service doesn't spin up an unbounded number of goroutines.

Quick Start

Use the golang-concurrency-patterns skill to implement a bounded fan-out pattern for processing a list of items concurrently.
