Why Update Angular CLI?

Updating Angular CLI is crucial for several reasons. First, each new version often includes performance enhancements, new features, and fixes for known bugs. By updating, you ensure that you’re using the most stable and efficient version of the tool. Additionally, staying updated helps in maintaining compatibility with new Angular releases and libraries.

Method 1: Using npm to Update Angular CLI

The most common way to update Angular CLI is through npm (Node Package Manager). This method is straightforward and widely used by developers. Here’s how you can do it:

1. First, you need to uninstall the current version of Angular CLI globally. Open your terminal and run the following command:

 bashCopynpm uninstall -g @angular/cli

2. After uninstalling, install the latest version of Angular CLI with this command:

 bashCopynpm install -g @angular/cli

3. To verify the installation, you can check the version of Angular CLI by running:

 bashCopyng --version

Output:

 textCopyAngular CLI: 14.0.0
Node: 16.0.0
Package Manager: npm 7.0.0
OS: win32 x64

By following these steps, you have successfully updated Angular CLI to the latest version. The first command removes the existing version, while the second command installs the latest one. Finally, the last command confirms that the update was successful by displaying the current version of Angular CLI.

Method 2: Updating Angular CLI Locally in a Project

If you want to update Angular CLI for a specific project rather than globally, you can do so by following these steps:

1. Navigate to your project directory in the terminal:

 bashCopycd your-angular-project

2. Uninstall the local Angular CLI version:

 bashCopynpm uninstall @angular/cli

3. Install the latest version locally:

 bashCopynpm install @angular/cli

4. Check the version to confirm the update:

 bashCopyng --version

Output:

 textCopyAngular CLI: 14.0.0
Node: 16.0.0
Package Manager: npm 7.0.0
OS: win32 x64

This method is particularly useful when you are working on multiple projects that may require different versions of Angular CLI. By uninstalling and reinstalling the CLI locally, you ensure that your project is using the latest features without affecting other projects.

Conclusion

Updating Angular CLI is a straightforward process that can significantly enhance your development experience. By using npm, you can ensure that you are always working with the latest features and improvements. Whether you are updating globally or locally within a project, the steps outlined in this tutorial will help you maintain your Angular environment efficiently. Regularly updating your tools is a best practice that leads to better performance, security, and compatibility.
