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: "Next, open the IDE of your preference, create a new Node.js project, and install the ibmiotf dependency package."

A block of code is set as follows:

{
  "org": "<your iot org id>",
  "id": "<any application name>",
  "auth-key": "<application authentication key>",
  "auth-token": "<application authentication token>"
}

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

"successRedirect": “<redirection URL. will be overwritten by the property 'json: true'>”,
"failureRedirect": "/?success=false",
"session": true,

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

$ npm start
> [email protected] start /sample-device

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: "From the IoT Platform service created in the setup step, select Devices in the menu and then select Add Device."
