With the rapid development of Internet technology, various programming languages are emerging one after another, and various open source projects are constantly emerging. Among them, golang is highly regarded as an emerging programming language. Golang is committed to improving programmers' development efficiency while maintaining efficient running speed. So, how to use golang to create a new project? This article will introduce you to the project creation process of golang.
1. Preparation work
Before starting to create a golang project, we need to ensure that the golang development environment has been installed. For the installation and configuration of golang, please refer to the official documentation. In addition, before creating a golang project, we also need to clarify the goals and scale of the project to choose an appropriate project framework.
2. Select project framework
golang provides many excellent project frameworks, such as gin, beego, echo, etc. These frameworks basically cover most of the functional requirements, have the advantages of efficiency, speed, and simplicity, and provide strong support for our projects. Next, take the gin framework as an example to introduce how to create a new project.
3. Create a project
- Create a project directory
First, you need to select a directory locally, and then create a new project directory in that directory . In the project directory, we need to create the main.go file and a config directory (optional). The config directory is used to store configuration files.
- Create the main.go file
Write the golang program in the main.go file. Here we take outputting "Hello World!" as an example. The detailed code is as follows:
package main
import (
"fmt"
)
func main() {
fmt.Println("Hello World!")
}
- Run the program in the terminal
In the project directory, use the go run command to run the main.go file:
go run main.go
Running results:
Hello World!
4. Project structure
A basic golang project structure should contain the following files or directories:
my_project
├── main. go
├── README.md
├── config
│ ├── config.yaml
│ ├── database.yaml
│ └── ...
├── static
│ ├── css
│ └── js
└── templates
├── index.html ├── header.html └── ...
Among them, main.go is the program entry file, and the config directory is used to store the configuration Files, static stores static resource files (such as style sheets, scripts, etc.), and templates stores HTML templates.
5. Summary
The above is the basic process of creating a project in golang. I believe that through the introduction in this article, you can easily create your own golang project. Of course, the details of the project still require everyone to continue to explore and learn in practice. In the process of learning, you can refer to some excellent golang projects and continue to accumulate experience. Moreover, the first step in creating a good project is to think more, communicate more, constantly optimize your ideas and designs, and create better works.
