Readers should be familiar with Java, Maven, Git, and Unix/Mac terminal or the Windows Command Prompt. To work with the JavaScript recipes you also need to be familiar with JavaScript. Additional links are provided within the See more section of the recipes to explain the prerequisite technologies. To make best use of the book you should first read the book from beginning until the end, at least once. After this, or along with reading the book, you may execute the code provided within the code files following the directions given within the book, and within the repository's readme files. Example codes should specify names or IDs. You will have to replace them with the name and ID that you create. Finally, you should build the projects on your own following the book's content.

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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

Resources:
 MyFirstRestAPI:
 Type: AWS::ApiGateway::RestApi
 Properties:
 Name: Greeting API

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

GreetingResource:
  Type: AWS::ApiGateway::Resource
  Properties:
    RestApiId: !Ref MyFirstRestAPI
    ParentId: !GetAtt MyFirstRestAPI.RootResourceId

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

aws apigateway create-resource \
    --rest-api-id c82tpsb7ka \

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: "Select System info from the Administration panel."
