Conventions used

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

Code in text: 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: “In the following code snippet, we have an example of an Angular service that injects the HttpClient service and fetches data from the server using the HttpClient.get() method.”

A block of code is set as follows:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable} from 'rxjs';

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

//console output
Full Name: John Doe

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Users can create a new recipe by clicking on the New Recipe menu item located at the top right of the page.”
