Why Does Angular CLI Global Install Show '(cli-only)' Text With Package Version?

If you've ever used Angular CLI for your Angular projects, you might have noticed that after a global installation, the version number often displays with an appended (cli-only) text. But what does this mean, particularly for developers working on Windows environments?

Understanding Angular CLI

Angular CLI (Command Line Interface) is a tool that aids in the development and management of Angular applications. It simplifies the process of starting a new Angular project, adding features to existing ones, and managing dependencies. By installing Angular CLI globally, you can use it to generate projects quickly from any directory.

The '(cli-only)' Text

When you globally install Angular CLI using the npm install -g @angular/cli command, you might see the version accompanied by the (cli-only) suffix. This indicates that only the CLI tool itself has been installed globally, without the core Angular packages.

Importance of '(cli-only)'

Separation of Concerns: The (cli-only) designation highlights that the global installation of Angular CLI is independent of project-specific Angular core libraries. This helps in isolating CLI functionality from Angular's internal libraries, ensuring there's no version conflict across projects.

Project Dependencies: While Angular CLI handles project initiation and scaffolding on the global level, the individual Angular project still relies on project-specific dependencies specified in its package.json. This ensures each project can reference compatible versions of Angular libraries as needed.

Environment Setup: Displaying (cli-only) is particularly useful in large development environments. Different projects might use different versions of Angular, so having only the CLI globally avoids potential mismatches and conflicts.

Effects on Windows

On Windows, the global installation mechanism works similarly to other operating systems. However, Windows users need to be particularly aware of their system's PATH environment variable. This variable must be correctly configured to ensure seamless access to global packages, including Angular CLI.

Tips for Windows Users

Verify PATH Setup: Ensure the npm global packages directory is included in your system's PATH. Typically, this would be something like C:\Users<YourUsername>\AppData\Roaming\npm.

Version Consistency: Use nvm-windows to manage Node.js versions if you work on multiple projects with differing requirements. This can help avoid conflicts and ensure the (cli-only) versioning works as intended.

Local vs Global: Always check the local Angular versions in your project's package.json to avoid confusion. The global CLI version should not interfere with local project dependencies.

Conclusion

The appearance of the (cli-only) text next to the Angular CLI global install's package version serves as a reminder of the CLI tool's scope and functionality. It reassures developers that the global executable will not meddle with project-specific dependencies—a crucial aspect in maintaining version control and ensuring compatibility, whether you are working on a Windows system or any other platform.

Stay productive and happy coding with Angular!
