What is gonew?

gonew is a command-line tool designed by the official Go team to streamline project initialization. Using gonew, you can efficiently set up standardized project structures, minimize manual setup, and ensure that your project aligns with best practices throughout your development process.

Imagine the early stages of Go project setup. Typically, you’d have to create folders manually, initialize modules, or set up essential test files. gonew simplifies these steps, allowing you to set up with a single command.

How to initialize a Go project and install gonew

To use gonew, you’ll need Go installed on your device. After installing Go, you can initialize your project like so:

go mod init

You’ll need to set your $GOPATH environment variable, which Go uses to identify the desired path to your workspace. Here’s how you can set your $GOPATH on UNIX-based systems:

export GOPATH=$HOME/path_to_your_workspace

Then, you can install gonew with a simple go install command. Run this command to install the gonew command line tool:

go install golang.org/x/tools/cmd/gonew@latest

Getting started with gonew

After installing gonew, you can use and access the gonew command. You can use this command to create a new module like so:

gonew [options] srcmod dstmod

The srcmod argument specifies the path to the template module you want to copy. The dstmod argument is the path of the new module you’re creating.

For example, you can use the gonew command to create a new module named myproject by copying the template module golang.org/x/example/helloserver:

gonew golang.org/x/example/helloserver myproject

gonew supports additional options that you can use to customize processes. These include:

• dir specifies the directory where the new module will be created. If this option is not specified, the new module will be created in the current directory
• v is the verbose output. This option will print more information about creating the new module

See an example of these in action below:

gonew -dir /my/projects/dir -v golang.org/x/example/helloserver myproject

This updated command will create a new Go module named myproject in the directory /my/projects/dir. The -v option will print more information about creating the new module.

In the example below, you can see the result of my attempt to use the project structure of the popular google/uuid package:

As you can see, gonew has set the directory structure of the google/uuid package for use in the specified project directory.

Exploring gonew features

Although gonew is simple to set up and use, this simplicity doesn’t compromise its feature set and core functionality. gonew can simplify project initialization, use tailored templates for different project types and workflows, and improve your dependency management integration.

Simplified project initialization

gonew isn’t just a tool — it’s like having a personal assistant for starting Go projects. With a single command, you can initialize new modules, create a directory structure that adheres to good practices, and add default configuration files and dependencies.

Tailored templates

Maintaining a consistent file structure and naming convention across projects can have many benefits, whether you’re doing so for personal preferences or as a best practice in a team setting.

When it comes to recreating the same structures or files across different Go projects, gonew has you covered. With the gonew templating feature, you can use predefined templates for various project types, including web apps, CLIs, and more.

You can even customize gonew templates to match your workflow. These templates are easy to share across teams, ensuring consistency and efficiency during the development process.

Integrated dependency management

Go has built-in functionality for dependency management. However, gonew takes this a step further by suggesting popular packages based on your project type. It also offers insights into dependency stats to help you choose the right dependencies for your needs.

Benefits of using gonew

There are many benefits of using gonew to streamline Go application development. For example, you can use gonew to:

• Save time: Creating a new Go project from scratch can be time-consuming, especially if you must manually create all the necessary files and directories. gonew can automate this process so that you can get started on your code faster
• Create a consistent project structure: gonew creates projects with a consistent structure. This can make your code easier to maintain and understand, especially for large or complex projects
• Provide a starting point for custom code and features: gonew creates projects with empty files, which means you can add your code and features without worrying about overwriting existing code. This gives you a blank slate that you can customize further as needed

Automating these aspects of Go project setup with gonew allows you to focus less on configuration and more on coding. This can enhance productivity while still ensuring your project follows best practices from the very beginning.

Typical use cases for gonew

gonew is handy for both new and experienced Go developers.

Frontend developers just getting started with Go can enjoy a simplified setup process that saves time by automating the creation of necessary files and structures. This also provides a great way to learn about structuring Go projects.

Meanwhile, gonew can help advanced Go developers start projects quickly and ensure consistency in project structure, which is particularly crucial in a professional or team environment.

For more complex projects, features like tailored templates and integrated dependency management can provide better organization, easier maintenance, and a more streamlined, efficient workflow.

Some typical use cases for gonew include:

• Command-line apps: Creating a command-line application is a great way to get started with Go development
• Web apps: You can use gonew to create a simple web application quickly
• New libraries: Using gonew to create new libraries for other Go apps is a great way to interoperate your code with other necessary functionalities
• Test suites: You can use gonew to create test suites for your application to ensure your code’s quality

No matter what kind of Go application you want to develop, Go can help you establish a well-organized foundation and write quality code throughout your whole project.

Limitations of and potential improvements for gonew

gonew is highly experimental and subject to change as newer versions of Go and the package itself roll out. Although it’s already a useful tool, there is still room for improvement.

Here’s a list of potential improvements that could benefit Go developers using gonew:

• Allow custom project structures: Currently, gonew creates projects with a fixed structure. This limitation can impede users who want to customize the structure to their project specifications
• Support more features: Gonew only supports a few sets of features. It would be helpful if gonew supported more features, such as unit testing, continuous integration, and deployment

You can contribute to gonew by proposing your ideas for functionalities you want to see and use.

Conclusion

The software industry is constantly evolving, which makes it critical for developers to have efficient tools that help enhance their workflow. gonew is a standout tool in this regard, especially for Go developers.

gonew can be the difference between a good and great start in developing Go projects. It can provide a head start in creating standardized, efficient, and scalable applications.

It’s also important to keep in mind that gonew is still evolving as well. Make sure you stay adaptable should the tool undergo major changes in the future, such as the potential improvements suggested above.

In essence, gonew is not just a tool but a companion for Go developers, making the development journey smoother and more efficient from the get-go. If you’re a Go developer looking to streamline project initialization and adhere to best practices, gonew is a tool worth considering.
