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: "Import Button to the AddCar.js file."

A block of code is set as follows:

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-web</artifactId>
</dependency>

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

public class Car { 
    @Id 
    @GeneratedValue(strategy=GenerationType.AUTO) 
    private long id; 
    private String brand, model, color, registerNumber; 
    private int year, price; 
}

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

npm install component_name

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "You can select the Run menu and press Run as | Java Application."
