To generate the dashboard component, the following is provided:

ng generate component component/dashboard

should read:

ng generate component components/dashboard

Building the dashboard.component.ts file, the ngOnInit and ngOnDestory methods reference this.subscription, which has not been defined. The page fails with compilation errors.

When adding the "manage" widget to the main page, the text errantly instructs to edit the src/index.html and then lists content to be modified in the app.component.html file.

The ng generate command creates elements with the app-, kebab leader. e.g. app-dashboard. The code in the book references using <dashboard>... In order to use the generated code, the HTML would have to reference the <app-dashboard> tag or alter the selector.

Thanks for the notes.

* Fixed the components pluralization for the next release
* The subscription see here https://forums.manning.com/posts/list/39748.page
* Fixed the file listing for index.html for the next release
* The `app-` prefix is generated by default, but the code listings I provide remove it. You are right though, if you left the `app-` prefix you would need to declare the HTML with it as well.
