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: “The Comment entity represents the comments posted on photos. It contains the comment text, user_id of the commenter, photo_id of the associated photo, and creation timestamp.”

A block of code is set as follows:

Request:
{
  "userId": "12345",
  "restaurantId": "78566",
  "items": [
    {
      "itemId": "item1",
      "quantity": 4
    },
    {
      "itemId": "item2",
      "quantity": 3
    }
  ],
  "paymentMethod": "credit_card"
}

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: “ The Photo Upload Service will expose the following API endpoints.”
