Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "AppModule is a root module with the @NgModule decorator that's used for defining a module."

A block of code is set as follows:

@NgModule({
  declarations: [ AppComponent, PositivePipe ],
  exports:      [ AppComponent ],
  imports:      [ BrowserModule, AppRoutingModule ],  
  providers:    [ DashboardService ],
  bootstrap:    [ AppComponent]
})
export class AppModule { }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

this.stats = {
      bookings: 100,
      cancellations: 11,
      sales: 5000
    }

Any command-line input or output is written as follows:

ng new hello-ng-dashboard --routing
cd hello-ng-dashboard

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The page presents a form where you can specify the maven projects Group ID, Artifact ID, and Dependencies."

Warnings or important notes appear like this.

Tips and tricks appear like this.
