Golang framework source code best practice sharing

Go framework source code best practices include: adhering to Go specifications (maintaining consistency), using structured layout (reasonable organization), writing testable code (dependency injection), using error handling (robustness) and limiting exposure API (security). The Gin-gonic framework demonstrates the application of best practices by following these principles, including the use of standard coding conventions, layered structures, dependency injection, custom error types, and restricted routing.

Go framework source code best practice sharing

When writing an efficient and maintainable Go framework, follow the best practices to It's important. This article will explore some key best practices and provide practical examples to show how to apply them.

1. Follow Go specifications

• Follow the coding standards of the Go community, which will ensure the readability and consistency of the code.
• Use gofmt tool to format the code to keep the code style consistent.

2. Use structured layout

• Organize the code into a reasonable and easy-to-navigate directory and package structure.
• Use common hierarchical structures (such as domain, infrastructure, usecase) to isolate different functional components.

3. Write testable code

• Write code that is easy to test to ensure the maintainability and reliability of the framework.
• Use dependency injection to decouple components, making them easier to integrate and test.

4. Use error handling

• Always handle and propagate errors to ensure the robustness and understandability of the framework.
• Use the error package and the errors.Is function to represent and compare errors.

5. Limit exposed APIs

• Restrict the APIs exposed by the framework to improve encapsulation and security.
• Consider using private methods and interfaces to hide internal implementation details.

Practical case: Gin-gonic framework

Gin-gonic is a popular Go Web framework. Here's how to apply best practices in Gin:

• Follow Go specifications: Gin uses standard Go coding conventions and is formatted using the gofmt tool.
• Structured layout: Gin adopts a hierarchical structure to organize the code into domain, middleware, usecase and controller layers.
• Testable: Gin uses dependency injection and provides test helper functions to simplify testing.
• Error handling: Gin defines its own GinError type to represent errors, and always handles and propagates errors.
• Restricted API: Gin uses middleware and routing groups to restrict access to internal endpoints.

By following these best practices, you can write an efficient, maintainable, and testable Go framework that provides a solid and stable foundation for your applications.
