This book will need a basic installation of Node.js on your Windows, Mac, or Linux machine. Since this book relies on Angular CLI 6.0.8, at least Node.js 8.9.0 is required.

The code bundle for the book is also hosted on GitHub at https://github.com/PacktPublishing/Mastering-Angular-Components-Second-Edition. In case there's an update to the code, it will be updated on the existing GitHub repository.

We also have other code bundles from our rich catalog of books and videos available at https://github.com/PacktPublishing/. Check them out!

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: "Let's change the view encapsulation of our main component to use the ViewEncapsulation.None mode."

A block of code is set as follows:

import {Component, ViewEncapsulation} from '@angular/core';

@Component({
  selector: 'mac-root',
  templateUrl: './app.component.html',
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
  title = 'mac';
}

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

...
import {TaskService} from './tasks/task.service';
...
@NgModule({
...
 providers: [TaskService],
 ...
})
export class AppModule {
}

Sometimes, on large code excerpts that require you to implement code changes in existing code files, we use the following format:

• New or replaced code parts are marked in bold
• Already existing and irrelevant code parts are hidden using an ellipsis character

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

ng new mastering-angular-components --prefix=mac

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: "You should be able to see the generated application app with a welcome message saying Welcome to mac!"
