Which command is used to update Angular to the latest version?

Understanding the Angular Update Command

Angular is a powerful platform for building web applications and like with most software, it is continuously being improved and enhanced with new features and fixes. This necessitates updates to the latest version for an optimized development environment. This is achieved using the ng update command. This command is the correct way to update Angular to the latest version.

The command ng update is designed to update your Angular applications from one version to another, applying automatic migrations to fix breaking changes. This helps to ensure you're always working with the most recent, optimized sets of features and improvements that Angular has to offer.

ng update @angular/cli @angular/core

When the command is executed, it performs several operations:

  1. Checks the current version of your Angular packages.
  2. Queries the official Angular registry for the latest versions.
  3. If newer versions exist, it updates the relevant packages in your project.
  4. If necessary, it applies any migrations for breaking changes.

One important note is not all updates are done automatically. If the Angular developers determined that a certain version update could potentially change the app's behavior, an automatic migration is not done. Instead, the Angular Update Guide will provide manual instructions which need to be carried out by the developer.

The ng update command is hugely beneficial in maintaining your Angular applications. It simplifies the process of transitioning between Angular versions and allows developers to stay updated with the latest features, fixes, and performance improvements in Angular.

Understanding this command and using it appropriately is part of best practices for Angular development. It's an effortless way to ensure that Angular applications are always running on the latest, most efficient version of Angular. Other commands like ng upgrade, ng install latest, or ng new version are incorrect for updating Angular since these do not exist within the Angular CLI commands.
