Angular is a popular framework for building web applications, and the Angular CLI is an essential tool that helps developers create, manage, and maintain their projects with ease. To ensure that you have access to the latest features and performance improvements, it’s important to keep your Angular CLI up-to-date. In this article, we will guide you through the process of updating your Angular CLI to the latest version.

Prerequisites

Before you begin, make sure you have the following installed on your system:

  1. Node.js (version 12 or later)
  2. NPM (version 6 or later)
  3. Angular CLI (version 8 or later)

If you don’t have the Angular CLI installed, you can install it globally using the following command:

npm install -g @angular/cli

Step 1: Check the current Angular CLI version

To determine your current Angular CLI version, open a terminal and run the following command:

ng version

This command will display the current version of Angular CLI installed on your system.

Step 2: Update the global Angular CLI

To update the Angular CLI to the latest version, run the following command:

npm install -g @angular/cli@latest

This command will update the Angular CLI installed globally on your system to the latest version available.

Step 3: Update Angular CLI in your project

Before you update the Angular CLI in your project, it’s a good idea to create a backup, as some changes may not be backward compatible.

To update the Angular CLI within your existing Angular project, navigate to your project’s root directory and run the following command:

ng update @angular/cli

This command will update your project’s local Angular CLI and any related dependencies.

Step 4: Verify the update

After the update process is complete, check the updated Angular CLI version by running the following command:

ng version

The output should display the latest Angular CLI version.

Step 5: Update Angular packages in your project (optional)

To ensure that your project is fully up-to-date, you can also update the Angular packages by running the following command:

ng update @angular/core

This command will update the Angular core packages and any related dependencies.

Conclusion

Keeping your Angular CLI up-to-date is essential for staying current with the latest features and improvements in the Angular ecosystem.
