How to develop golang without internet

Golang is a popular programming language, but how to develop Golang without an Internet connection? This article will introduce some solutions.

First, in order to develop Golang without a network connection, you need to install the Golang compiler and related tool chains. During the installation process, you can optionally add the path to the toolchain to an environment variable. This allows you to use the compiler and related tools without a network connection.

Here are some tools and techniques that you can use when developing Golang without a network connection:

1. Using offline documentation

Golang has An official documentation site where you can find documentation for functions and data types. However, you will not be able to access this website without an internet connection. To solve this problem, you can download the Golang documentation and save it to your local computer. You can use the Godoc tool for offline documentation. After downloading the offline document, you can use the following command to start the offline document service:

godoc -http=:6060

Then open http://localhost:6060 in the browser to access the offline document service.

2. Using local packages

When you do Golang development without a network connection, you cannot download packages from the remote repository. So you need to use local packages. Local packages can be placed directly in the src directory under GOPATH. Local packages can be brought in using import statements in your source code. For example, assuming you create a package named demo in the src directory under GOPATH, you can introduce it using the following import statement:

import "demo"

3. Use local cache

When you use the go get command without a network connection, you will not be able to download code from the remote repository. However, you can use local caching to cache code for already downloaded repositories. To use the local cache, run the following command:

go get -u -d -v -tags netgo -ldflags "-w -s" <your-package>

In the above command, the -d option is used to download the package, the -v option is used to display the details, is the one you want to download The name of the package. This will download the code and cache it on your local machine. In future development, if this package needs to be used, Go will use it from the local cache.

4. Manage dependencies manually

When you do Golang development without a network connection, the go get command will not be able to resolve dependencies. To solve this problem, you can manage dependencies manually. This requires you to understand the structure and usage of your package and its dependencies. When using this approach, you need to manually set the path to the dependency in your code.

5. Using the offline editor

Finally, you can use the offline editor for Golang development without a network connection. There are some free and open source offline editors such as Visual Studio Code and Sublime Text. These editors do not require an internet connection to work and support Golang’s syntax highlighting and code completion features.

Summary

Developing in Golang without an internet connection requires some skills and tools. This article explains some solutions such as using offline documentation, local packages, local cache, manually managing dependencies, and using offline editors. Using these tips and tools, you can easily develop Golang without an internet connection.
