How do I correctly upgrade angular 2 (npm) to the latest version?

Question

Recently I started Angular 2 tutorial at https://angular.io/docs/ts/latest/tutorial/.

and left off with Angular 2 beta 8. Now I resumed the tutorial and latest beta

If you are looking like me for just updating your project to the latest these is what works form me since Angular 6:

Open the console on your project folder: If you type: ng update then you will get the below message:

        We analyzed your package.json, there are some packages to update:

          Name                               Version                  Command to update
         --------------------------------------------------------------------------------
          @angular/cli                       7.0.7 -> 7.2.2           ng update @angular/cli
          @angular/core                      7.0.4 -> 7.2.1           ng update @angular/core

There might be additional packages that are outdated.
    Run "ng update --all" to try to update all at the same time.

So I usually go straight and do:

ng update --all

Finally you can check your new version:

ng version
