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: "After this setup is done, we then start the server using the server.start method."

A block of code is set as follows:

handler: (request, reply) => 
{
  return reply({ message: 'hello, world' });
}

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

node server.js

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: "Change the request type to POST."

Activity: These are scenario-based activities that will let you practically apply what you've learned over the course of a complete section. They are typically in the context of a real-world problem or situation.
