How to Update Angular 17 to Angular 18 Version?

In this post, I will show you how to upgrade angular 17 to angular 18 version in ubuntu.

While working on my Angular project, I encountered the need to migrate from Angular 17 to Angular 18. Attempting to execute a straightforward update command proved unsuccessful, indicating that certain configurations were impacted. This prompted me to consider alternative methods for upgrading Angular.

There are two approaches to facilitate the transition from Angular 17 to 18. Initially, we'll attempt a direct update of the Angular CLI version. If this proves ineffective, an alternative solution involves uninstalling and reinstalling the Angular CLI, following the provided steps.

Following Way to Upgrade Angular 17 to 18 Version

• Way 1: Update Angular CLI
• Way 2: Update Angular CLI using reinstall

Let's see both ways:

Way 1: Update Angular CLI

You can directly upgrade your angular CLI version globally by using the update command of ng. so you can do it by bellow command.

ng update @angular/cli @angular/core

Now you can see ng version by following command:

I will show you list of commands for update version angular 17 to angular 18 by using uninstall and upgrade angular version.
