I. What is go mod?

Go modules are officially defined as:

A module is a collection of related Go packages.Modules are the unit of source code exchange and version control.
The go command directly supports the use of modules, including logging and resolving dependencies on other modules.modules replace the old GOPATH-based method of specifying which source files to use in a given build.

Second, detailed commands

1.init

Code:

go mod init

Generate a go.mod file. This command will initialize and create a new go.mod file in the current directory. Manually creating a go.mod file and including some module declarations is also equivalent to this command, and the go mod init command isHelp us make it easy, you can help us create it automatically.

2.download

Code:

go mod download

Download all dependencies specified in the go.mod file. Use this command to download the specified module. The format of the module can be specified according to the form of the main module dependency or the form of [email protected]

3.tidy

Code:

go mod tidy

Organize existing dependencies, use this command to download the specified module, and delete the modules that are no longer used

4.graph

Code:

go mod graph

View the existing dependency structure and generate a report of all dependencies of the project, but the readability is too poor, and the graphics are more convenient.

5.edit

Code:

go mod edit

Edit the go.mod file, then download or edit it

5.vendor

Code:

go mod vendor

Export all dependencies of the project to the vendor directory, copy from the mod to the vendor directory of the project, the IDE can recognize such a directory.

5.verify

Code:

go mod verify

Check whether a module has been tampered with, and check whether a common module error has been tampered with

5.why

Code:

go mod why

Check why you need to depend on a module, and check whether an uncommon module is a reference of which module

Summary

Through the above, it is easy to understand how to use go mod in Golang.Go mod provides a series of commands for manipulating modules, and module support is now built into all go commands, not just go mod commands.For example, when using go get, dependency package versions are often automatically added, removed, upgraded, and downgraded in the background.

Hope this blog will be useful to you.I am the King of Light, and I speak for myself.

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
