Go Dependency Management with Modules: Everything You Need to Know

May 25, 2025

Go has become a mainstream programming language in cloud computing and microservices due to its high performance and concise syntax. As project scales expand, traditional dependency management solutions (GOPATH + Vendor) increasingly reveal flaws in version conflicts, collaboration efficiency, and build reliability. Introduced in Go 1.11, Go Module—the official dependency management solution—restructures Go project dependency management through **modular design**, **semantic versioning**, and **automated dependency resolution**. This article dissects how Go Module achieves efficient and reliable dependency management from three dimensions: design principles, core components, and operational mechanisms.

Inside Go’s sync.WaitGroup: The Story Behind Goroutine Synchronization

May 24, 2025

`sync.WaitGroup` is a basic tool for handling goroutine synchronization in Go language concurrent programming. Its design fully reflects the engineering practice principles such as memory alignment optimization, atomic operation safety, and error checking. By deeply understanding its data structure and implementation logic, developers can use this tool more safely and efficiently and avoid common pitfalls in concurrent scenarios. In practical applications, it is necessary to strictly follow the specifications such as count matching and sequential calling to ensure the correctness and stability of the program.
