Tutorial "The Application Shell" is missing npm install part

[SetTrend]

The tutorial page "The Application Shell" is missing information about the fact that the user needs to manually download corresponding npm packages after an Angular web application has been created.

There are so many questions out there, e.g. on StackOverflow, of concerned programmers wondering why any ng command (except for ng --version they issue fails.

So I'd like to suggest to amend the tutorial to include the npm install command from

## Serve the application

Go to the project directory and launch the application.

<code-example language="sh" class="code-shell">
  cd angular-tour-of-heroes
  ng serve --open
</code-example>

to

## Serve the application

Go to the project directory, install Angular's npm packages and launch the application.

<code-example language="sh" class="code-shell">
  cd angular-tour-of-heroes
  npm install
  ng serve --open
</code-example>

In the "Create a new application" section it does say to run ng new angular-tour-of-heroes. That command runs npm install for you. The extra npm install that you're suggesting is redundant and won't help in this scenario.

Strange .. Apparently it doesn't always do that.

How are chances that option like --routing, --skip-commit, --skip-git, --skip-install, --skip-tests have influence on the initial creation of the npm packages?

The documentation isn't clear about the repercussions of these options.

if you ng new my-project --skip-install then npm install won't be invoked.

Ah, I see. Thanks for enlightening me!

I will close this issue. Though, I feel that the documentation should be enhanced on options, then new and occasional programmers can quickly grasp the implications of any of the CLI options.
