Go: Code Organization and Package Management Best Practices

Overview

Since its launch in 2009, Go language has rapidly gained widespread application in the software development industry due to its concise syntax, powerful standard library, and excellent concurrency support. Good code organization can greatly improve the maintainability and scalability of projects. This article aims to explore the best practices of code organization in Go language project development, including subcontracting principles, naming conventions, and package hierarchy recommendations.

Principle of subcontracting

In Go language, a package is a collection of multiple Go source files located in the same directory, and the package name is usually the same as the directory name. Reasonable packaging is an important part of Go language code organization.

1. Packaging by Function: Organize code with similar functionality in the same package. For example, the HTTPpackage handles HTTP requests, and the JSONpackage handles encoding and decoding of JSON data.
2. Avoid circular dependencies: Go language does not allow circular dependencies between packages. If circular dependencies are found, the package design should be reconsidered.
3. Make good use of subpackages: Subpackages are used to further organize the code in a large package. For…
