Follow the best practices of Go language for project development

As the Go language becomes more and more popular, more and more developers are beginning to use this language for project development. As the number of developers increases, the best practices of the Go language are gradually revealed. In this article, we will explore some ways to follow the best practices of the Go language to help developers better develop projects.

1. Application structure

When developing a project, the structure of the application is a very important link. In Go language, the structure of the application usually adopts the following method: put all the code related to the application function in the same folder, and use the main package to identify the entry point of the program. In addition, you need to explicitly declare the dependencies, add the vendor folder to the root directory of the project, and place all used dependencies in this folder.

2. Error handling

In the Go language, error handling is a very important part. When developing code, you need to ensure that all functions and methods can return error information. When handling errors, it's better to pass them up one level to the caller of the function rather than handling them directly inside the function.

3. Interfaces and code reuse

Using interfaces and code reuse are very common behaviors in code development. In Go language, interfaces usually adopt the single responsibility principle. When designing interfaces, you need to ensure that each interface has only one well-defined function. In addition, in terms of code reuse, the Go language has a very powerful feature - combination. By combining different structures together, code reuse can be easily achieved.

4. Concurrency and Parallelism

Go language has very powerful concurrency and parallel support. When developing applications, you can use the coroutines and channels of the Go language to perform very efficient concurrency and parallel operations. When performing concurrent operations, you need to pay attention to controlling the number of coroutines to avoid excessive system load due to too many coroutines.

5. Testing

Testing is a very important part of code development. When testing your code, you need to cover as many different situations and exceptions as possible. In the Go language, there are very powerful testing frameworks available, such as testing, gocheck, etc. In addition, you also need to pay attention to taking testing into consideration when writing code, and write code that is easy to test.

Best Practice Summary

The above aspects are just the tip of the iceberg of best practices in Go language. When developing Go language, you need to pay close attention to the best practices of Go language, such as:

• Write code that is highly readable, modular, and easy to maintain;
• Use appropriate Naming method;
• Don’t abuse pointers;
• Avoid using global variables or global constants;
• Use meaningful comments;
• Those who are familiar with Go language Standard library, and select appropriate third-party libraries according to needs.

In short, mastering the best practices of Go language can effectively improve the quality of code, speed up development efficiency, and also make our code easier to maintain, expand and refactor.
