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: “If we are using Link in any of the models, then the generated models would use the mapped org.springframework.hateoas.Link class instead of the model defined in the YAML file.”

A block of code is set as follows:

 const Footer = () => {   return (
     <div>
       <footer
         className="text-center p-2 border-t-2 bggray-
           200 border-gray-300 text-sm">
         No &copy; by Ecommerce App.{" "}
         <a href=https://github.com/PacktPublishing/Modern- 
           API-Development-with-Spring-and-Spring-Boot>
           Modern API development with Spring and Spring Boot
         </a>
       </footer>
     </div>
   );
 };
 export default Footer;

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

<Error>  <errorCode>PACKT-0001</errorCode>
  <message>The system is unable to complete the request. 
      Contact system support.</message>
  <status>500</status>
  <url>http://localhost:8080/api/v1/carts/1</url>
  <reqMethod>GET</reqMethod>
</Error>

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

$ curl --request POST 'http://localhost:8080/api/v1/carts/1/items' \ --header 'Content-Type: application/json' \ 
 --header 'Accept: application/json' \ 
 --data-raw '{ 
 "id": "1", 
 "quantity": 1, 
 "unitPrice": 2.5 
 }'
[]

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: “Select System info from the Administration panel.”
