Go get vs. Go install: When to Use Which Command?

Distinguishing between 'go get' and 'go install' for Go Development

While exploring the Go toolchain, a common question arises regarding the distinction between 'go get' and 'go install'. Understanding their differences is crucial for effective Go development.

'go get' serves as a comprehensive command that performs multiple tasks:

• Downloads the package from the appropriate repository
• Compiles the package into an executable or library
• Installs the package into the local Go path

In contrast, 'go install' has a narrower scope:

• Compiles the package
• Installs the package into the local Go path

When to Use 'go get' and 'go install'?

The choice between 'go get' and 'go install' depends on the development workflow:

• Downloading and Using a Remote Library:

For incorporating a remote library into a project, 'go get' is the preferred approach. Its ability to download and install the library automates the process.

• Developing a Local Package:

In scenarios where you're creating a local package for development, 'go install' is suitable. With 'go get' no longer having the option to skip downloading, it falls short in this scenario. To modify and install a local package, you can use:

go get -d library
(Make changes to the package)
go install library

Evolution of 'go get' and 'go install' in Go 1.16

Go 1.16 introduced significant improvements to the Go toolchain, clarifying the usage of 'go get' and 'go install':

• 'go install' is now the recommended command for building and installing packages in module mode.
• 'go get' with the '-d' flag is intended for modifying module dependencies without building packages.
• The '-d' flag will be enabled by default in future Go releases, deprecating the use of 'go get' for building and installing packages.
