Let's talk in depth about golang's directory structure

Golang, as an efficient, reliable, and fast programming language, has been favored by developers since its release. Golang has fewer annotations and a smaller function call stack than other languages, making it better at handling multiple tasks simultaneously. But as a relatively new language, its learning curve may be relatively steep. One of the things that needs to be learned is the use of Golang directories. Here is some introduction to Golang directories.

Golang’s directory structure

Golang’s directory structure is relatively simple and somewhat different from that of other programming languages. Usually, Golang projects will establish a GOPATH as the root directory of the project file. GOPATH contains three important directories. The src directory is the main source code directory of the Golang project, and pkg and bin store the program's libraries and binary files.

In the src directory, the programmer needs to create a project folder containing the specified name. For example, if the project name is myproject, the creation path should be as follows:

$GOPATH/src/myproject

In the myproject folder , you can create various package folders, as well as the main function file of the project. Library files should generally be placed in the package folder, while unrelated files should not be placed there.

Deployment of Golang directory

After completing the creation of the Golang project folder, you can write and deploy the code. In order for the Golang project to include only necessary dependencies, it needs to be installed using the go get command, which downloads the specified dependencies from the remote warehouse and saves them to the pkg directory in the GOPATH folder.

For example, to install the goplayground/assert library, use the following command:

$ go get github.com/goplayground/assert

Import of Golang directory

Once the library files are installed, we can Import statements are used in the code to import them. For example, in our myproject project, if we want to use code from the goplayground/assert library, we can add the following code at the top of some .go file:

import "github.com/goplayground/assert"

This will tell the Golang compiler to import from this library assert package and make it available to all code in that file.

Summary

The creation and use of Golang directories may have a learning curve for novices, but once you are familiar with the process, you will be able to create your own Golang project more easily. In addition to creating the directory structure, you also need to know how to import library files and how to use the go get command to install the necessary dependencies. Mastering these skills will enable you to write efficient, reliable, and fast Golang programs more quickly.
